■ Management interfaces for the switches covered in this guide
■ Advantages of using each interface
Understanding Management Interfaces
Management interfaces enable you to reconfigure the switch and to monitor
switch status and performance. The switch offers the following interfaces:
■ Menu interface—a menu-driven interface offering a subset of switch
commands through the built-in VT-100/ANSI console—2-3
■ CLI—a command line interface offering the full set of switch commands
through the VT-100/ANSI console built into the switch—2-4
■ Web browser interface --a switch interface offering status information
and a subset of switch commands through a standard web browser (such
as Netscape Navigator or Microsoft Internet Explorer)—2-5
■ ProCurve Manager (PCM)—a windows-based network management
solution included in-box with all manageable ProCurve devices. Features
include automatic device discovery, network status summary, topology
and mapping, and device management.
■ ProCurve Manager Plus (PCM+)—a complete windows-based
network management solution that provides both the basic features
offered with PCM, as well as more advanced management features,
including in-depth traffic analysis, group and policy management, config-
uration management, device software updates, and advanced VLAN
management. (ProCurve includes a copy of PCM+ in-box for a free 30-day
trial.)
This manual describes how to use the menu interface (Chapter 3), the CLI
(Chapter 4), the web browser interface (Chapter 5), and how to use these
interfaces to configure and monitor the switch.
For information on how to access the web browser interface Help, see “Online
Help for the Web Browser Interface” on page 5-11.

Selecting a Management Interface
Advantages of Using the Menu Interface
To use ProCurve Manager or ProCurve Manager Plus, refer to the Getting
Started Guide and the Administrator’s Guide, which are available electron-
ically with the software for these applications. For more information, visit the
ProCurve Networking web site at www.procurve.com.
Advantages of Using the Menu Interface
Figure 2-1. Example of the Console Interface Display
■ Provides quick, easy management access to a menu-driven subset of
switch configuration and performance features:
• IP addressing • System information
• VLANs and GVRP • Local passwords
• Port Security •SNMP communities
• Port and Static Trunk Group • Time protocols
• Spanning Tree
The menu interface also provides access for:
•Setup screen • Switch and port statistic and counter displays
• Event Log display • Reboots
• Switch and port • Software downloads
status displays
■ Offers out-of-band access (through the RS-232 connection) to the
switch, so network bottlenecks, crashes, lack of configured or correct IP
address, and network downtime do not slow or prevent access
2-3
Selecting a Management Interface
Advantages of Using the CLI
■ Enables Telnet (in-band) access to the menu functionality.
■ Allows faster navigation, avoiding delays that occur with slower
display of graphical objects over a web browser interface.
■ Provides more security; configuration information and passwords are
not seen on the network.
Advantages of Using the CLI

General Benefits
■ Provides access to the complete set of the switch configuration, perfor-
mance, and diagnostic features.
■ Offers out-of-band access (through the RS-232 connection) or Telnet (in-
band) access.
■ Enables quick, detailed system configuration and management access to
system operators and administrators experienced in command prompt
interfaces.
■ Provides help at each level for determining available options and vari-
ables.
Information on Using the CLI
■ For information on how to use the CLI, refer to Chapter 4. “Using the
Command Line Interface (CLI)”.

Selecting a Management Interface
Advantages of Using the Web Browser Interface
■ To perform specific procedures (such as configuring IP addressing or
VLANs), use the Contents listing at the front of the manual to locate the
information you need.
■ For monitoring and analyzing switch operation, refer to Appendix B.
■ For information on individual CLI commands, refer to the Index or to the
online Help provided in the CLI interface.
Advantages of Using the Web Browser
Interface
Figure 2-3.Example of the Web Browser Interface
■ Easy access to the switch from anywhere on the network
■ Familiar browser interface--locations of window objects consistent
with commonly used browsers, uses mouse clicking for navigation, no
terminal setup
■ Many features have all their fields in one screen so you can view all
values at once
2-5
Selecting a Management Interface
Advantages of Using ProCurve Manager or ProCurve Manager Plus
■ More visual cues, using colors, status bars, device icons, and other
graphical objects instead of relying solely on alphanumeric values
■ Display of acceptable ranges of values available in configuration list
boxes
Advantages of Using ProCurve Manager
or ProCurve Manager Plus
You can operate ProCurve Manager and ProCurve Manager Plus (PCM and
PCM+) from a PC on the network to monitor traffic, manage your hubs and
switches, and proactively recommend network changes to increase network
uptime and optimize performance. Easy to install and use, PCM and PCM+ are
the answers to your management challenges.
PCM and PCM+ enable greater control, uptime, and performance in your
network:
■ Features and benefits of ProCurve Manager:
• Network Status Summary: Upon boot-up, a network status screen
displays high-level information on network devices, end nodes,
events, and traffic levels. From here, users can research any one of
these areas to get more details.
• Alerts and Troubleshooting: An events summary screen displays
alerts to the user and categorizes them by severity, making it easier
to track where bottlenecks and issues exist in the network. Alerts
present detailed information on the problem, even down to the spe-
cific port.
• Automatic Device Discovery: This feature is customized for fast
discovery of all ProCurve manageable network devices. The user can
define which IP subnets to discover.
• Topology and Mapping: This feature automatically creates a map of
discovered network devices. Maps are color-coded to reflect device
status and can be viewed at multiple levels (physical view, subnet
view, or VLAN view).
• Device Management: Many device-focused tasks can be performed
directly by the software, or the user can access web-browser and
command-line interfaces with the click of a button to manage individ-
ual devices from inside the tool.
■ Features and benefits of ProCurve Manager Plus:
• All of the Features of ProCurve Manager: Refer to the above
listing.
2-6
Selecting a Management Interface
Advantages of Using ProCurve Manager or ProCurve Manager Plus
• In-Depth Traffic Analysis: An integrated, low-overhead traffic mon-
itor interface shows detailed information on traffic throughout the
network. Using enhanced traffic analysis protocols such as Extended
RMON, users can monitor overall traffic levels, segments with the
highest traffic, or even the top users within a network segment.
• Group and Policy Management: Changes in configuration are
tracked and logged, and archived configurations can be applied to one
or many devices. Configurations can be compared over time or
between two devices, with the differences highlighted for users.
• Advanced VLAN Management: A new, easy-to-use VLAN manage-
ment interface allows users to create and assign VLANs across the
entire network, without having to access each network device indi-
vidually.
• Device Software Updates: This feature automatically obtains new
device software images from ProCurve and updates devices, allowing
users to download the latest version or choose the desired version.
Updates can be scheduled easily across large groups of devices, all at
user-specified times.
• Investment Protection: The modular software architecture of Pro-
Curve Manager Plus will allow ProCurve to offer network administra-
tors add-on software solutions that complement their needs.

Selecting a Management Interface
Custom Login Banners for the Console and Web Browser Interfaces
Custom Login Banners for the Console
and Web Browser Interfaces
You can now configure the switch to display a login banner of up to 3070
characters when an operator initiates a management session with the switch
through any of the following methods:
■ Telnet
■ serial connection
■ SSHv2
■ Web browser
The default banner displays product registration information; the copyright
splash is no longer displayed.
If a banner is configured, the banner page is displayed when you access the
Web user interface. The default product registration information is not
displayed as there is already a product registration prompt displayed in the
Web user interface.
Banner Operation with Telnet, Serial, or SSHv2 Access
When a system operator begins a login session, the switch displays the banner
above the local password prompt or, if no password is configured, above the
Press any key to continue prompt. Entering a correct password or, if no password
is configured, pressing any key clears the banner from the CLI and displays
the CLI prompt. (Refer to Figure 2-5 on page 2-10.)
Banner Operation with Web Browser Access
When a system operator uses a Web browser to access the switch, the text of
a non-default banner configured on the switch appears in a dedicated banner
window with a link to the Web agent home page. Clicking on To Home Page
clears the banner window and prompts the user for a password (if configured).
Following entry of the correct username/password information (or if no
username/password is required), the switch then displays either the Registra-
tion page or the switch’s home page. Note that if the banner feature is disabled
2-8
Selecting a Management Interface
Custom Login Banners for the Console and Web Browser Interfaces
or if the switch is using the factory-default banner shown in figure 2-5, then
the banner page does not appear in the Web browser when an operator
initiates a login session with the switch.
Configuring and Displaying a Non-Default Banner
You can enable or disable banner operation using either the switch’s CLI or
an SNMP application. The steps include:
1. Enable non-default banner operation and define the endpoint delimiter
for the banner.
2. Enter the desired banner text, including any specific line breaks you
want.
3. Enter the endpoint delimiter.
Use show banner motd to display the current banner status.
Syntax: banner motd < delimiter >
no banner motd
This command defines the single character used to termi-
nate the banner text and enables banner text input. You
can use any character except a blank space as a delimiter.
The no form of the command disables the login banner
feature.
< banner-text-string >
The switch allows up to 3070 banner characters,
including blank spaces and CR-LF ([Enter]). (The tilde “ ~“
and the delimiter defined by banner motd <delimiter> are
not allowed as part of the banner text.) While entering
banner text, you can backspace to edit the current line
(that is, a line that has not been terminated by a CR-LF.)
However, terminating a line in a banner by entering a
CR-LF prevents any further editing of that line. To edit a
line in a banner entry after terminating the line with a
CR-LF requires entering the delimiter described above
and then re-configuring new banner text.
The banner text string must terminate with the character
defined by banner motd < delimiter >.
Example of Configuring and Displaying a Banner
Suppose a system operator wanted to configure the following banner message
on her company’s switches:
2-9
Selecting a Management Interface
Custom Login Banners for the Console and Web Browser Interfaces
This is a private system maintained by the
Allied Widget Corporation.
Unauthorized use of this system can result in
civil and criminal penalties!
In this case, the operator will use the [Enter] key to create line breaks, blank
spaces for line centering, and the % symbol to terminate the banner message.
Figure 2-4. Example of Configuring a Login Banner
To view the current banner configuration, use either the show banner motd or
show running command.

Operating Notes
■ The default banner appears only when the switch is in the factory
default configuration. Using no banner motd deletes the currently
configured banner text and blocks display of the default banner. The
default banner is restored only if the switch is reset to its factory-
default configuration.
■ The switch supports one banner at any time. Configuring a new
banner replaces any former banner configured on the switch.
■ If the switch is configured with ssh version 1 or ssh version 1-or-2,
configuring the banner sets the SSH configuration to ssh version 2
and displays the following message in the CLI:
Warning: SSH version has been set to v2.
■ If a banner is configured, the switch does not allow configuration with
ssh version 1 or ssh version 1-or-2. Attempting to do so produces the
following error message in the CLI:
Banner has to be disabled first.
■ If a banner is enabled on the switch, the Web browser interface
displays the following link to the banner page:

Using the Menu Interface
Overview
Overview
This chapter describes the following features:
■ Overview of the Menu Interface (page 3-2)
■ Starting and ending a Menu session (page 3-3)
■ The Main Menu (page 3-7)
■ Screen structure and navigation (page 3-9)
■ Rebooting the switch (page 3-12)
The menu interface operates through the switch console to provide you with
a subset of switch commands in an easy-to-use menu format enabling you to:
■ Perform a “quick configuration” of basic parameters, such as the IP
addressing needed to provide management access through your network
■ Configure these features:
• Manager and Operator • A network monitoring port
passwords • SNMP community names
• System parameters • IP authorized managers
• IP addressing • VLANs (Virtual LANs) and GVRP
• Time protocol
•Ports
• Trunk groups
■ View status, counters, and Event Log information
■ Update switch software
■ Reboot the switch
For a detailed list of menu features, see the “Menu Features List” on page 3-14.
Privilege Levels and Password Security. ProCurve strongly recom-
mends that you configure a Manager password to help prevent unauthorized
access to your network. A Manager password grants full read-write access to
the switch. An Operator password, if configured, grants access to status and
counter, Event Log, and the Operator level in the CLI. After you configure
passwords on the switch and log off of the interface, access to the menu
interface (and the CLI and web browser interface) will require entry of either
the Manager or Operator password. (If the switch has only a Manager pass-
word, then someone without a password can still gain read-only access.)
3-2
Using the Menu Interface
Starting and Ending a Menu Session
Note If the switch has neither a Manager nor an Operator password, anyone
having access to the console interface can operate the console with full
manager privileges. Also, if you configure only an Operator password,
entering the Operator password enables full manager privileges.
For more information on passwords, refer to the Access Security Guide for
your switch.
Menu Interaction with Other Interfaces.
■ The menu interface displays the current running-config parameter set-
tings. You can use the menu interface to save configuration changes made
in the CLI only if the CLI changes are in the running config when you save
changes made in the menu interface. (For more on how switch memory
manages configuration changes, see Chapter 6, “Switch Memory and
Configuration”.)
■ A configuration change made through any switch interface overwrites
earlier changes made through any other interface.
■ The Menu Interface and the CLI (Command Line Interface) both use the
switch console. To enter the menu from the CLI, use the menu command.
To enter the CLI from the Menu interface, select Command Line (CLI) option.)
Starting and Ending a Menu Session
You can access the menu interface using any of the following:
■ A direct serial connection to the switch’s console port, as described in the
installation guide you received with the switch
■ A Telnet connection to the switch console from a networked PC or the
switch’s web browser interface. Telnet requires that an IP address and
subnet mask compatible with your network have already been configured
on the switch.
Note This section assumes that either a terminal device is already configured and
connected to the switch (see the Installation and Getting Started Guide
shipped with your switch) or that you have already configured an IP address
on the switch (required for Telnet access).
3-3
Using the Menu Interface
Starting and Ending a Menu Session
How To Start a Menu Interface Session
In its factory default configuration, the switch console starts with the CLI
prompt. To use the menu interface with Manager privileges, go to the Manager
level prompt and enter the menu command.
1. Use one of these methods to connect to the switch:
• A PC terminal emulator or terminal
• Telnet
2. Do one of the following:
• If you are using Telnet, go to step 3.
• If you are using a PC terminal emulator or a terminal, press [Enter] one
or more times until a prompt appears.
3. When the switch screen appears, do one of the following:
• If a password has been configured, the password prompt appears.
Password: _
Type the Manager password and press [Enter]. Entering the Manager
password gives you manager-level access to the switch. (Entering the
Operator password gives you operator-level access to the switch.
Refer to the Access Security Guide for your switch.)
• If no password has been configured, the CLI prompt appears. Go to
the next step.
4. When the CLI prompt appears, display the Menu interface by entering the
menu command. For example:
ProCurve# menu [Enter]
results in the following display:

Figure 3-1. Example of the Main Menu with Manager Privileges
For a description of Main Menu features, see “Main Menu Features” on page 3-
7.
Note To configure the switch to start with the menu interface instead of the CLI, go
to the Manager level prompt in the CLI, enter the setup command, and in the
resulting display, change the Logon Default parameter to Menu. For more
information, see the Installation and Getting Started Guide you received
with the switch.
How To End a Menu Session and Exit from the Console:
The method for ending a menu session and exiting from the console depends
on whether, during the session, you made any changes to the switch configu-
ration that require a switch reboot to activate. (Most changes via the menu
interface need only a Save, and do not require a switch reboot.) Configuration
changes needing a reboot are marked with an asterisk (*) next to the config-
ured item in the menu and also next to the Switch Configuration item in the
Main Menu.
3-5
Using the Menu Interface
Starting and Ending a Menu Session
Asterisk indicates a
configuration change
that requires a reboot
to activate.
Figure 3-2. Example Indication of a Configuration Change Requiring a Reboot
1. In the current session, if you have not made configuration changes that
require a switch reboot to activate, return to the Main Menu and press [0]
(zero) to log out. Then just exit from the terminal program, turn off the
terminal, or quit the Telnet session.
2. If you have made configuration changes that require a switch reboot—
that is, if an asterisk (*) appears next to a configured item or next to Switch
Configuration in the Main Menu:
a. Return to the Main Menu.
b. Press [6] to select Reboot Switch and follow the instructions on the
reboot screen.
Rebooting the switch terminates the menu session, and, if you are using
Telnet, disconnects the Telnet session.
(See “Rebooting To Activate Configuration Changes” on page 3-13.)
3. Exit from the terminal program, turn off the terminal, or close the Telnet
application program.

The Main Menu gives you access to these Menu interface features:
■ Status and Counters: Provides access to display screens showing
switch information, port status and counters, and port and VLAN address
tables. (Refer to Appendix B, “Monitoring and Analyzing Switch Opera-
tion”.)
■ Switch Configuration: Provides access to configuration screens for
displaying and changing the current configuration settings. (See the Con-
tents listing at the front of this manual.) For a listing of features and
parameters configurable through the menu interface, see the “Menu Fea-
tures List” on page 3-14. For an index of the features covered in the
software manuals for your switch, refer to the “Software Feature Index”
on page -xx.
■ Console Passwords: Provides access to the screen used to set or change
Manager-level and Operator-level passwords, and to delete Manager and
Operator password protection. (Refer to the chapter on configuring user-
names and passwords in the Access Security Guide for your switch.)
■ Event Log: Enables you to read progress and error messages that are
useful for checking and troubleshooting switch operation. (See “Using the
Event Log for Troubleshooting Switch Problems” on page C-22.)

Main Menu Features
■ Command Line (CLI): Selects the Command Line Interface at the same
level (Manager or Operator) that you are accessing in the Menu interface.
(Refer to Chapter 4, “Using the Command Line Interface (CLI)”.)
■ Reboot Switch: Performs a “warm” reboot of the switch, which clears
most temporary error conditions, resets the network activity counters to
zero, and resets the system up-time to zero. A reboot is required to activate
a change in the VLAN Support parameter. (See “Rebooting from the Menu
Interface” on page 6-11.)
■ Download OS: Enables you to download a new switch software version
to the switch. (See Appendix A, “File Transfers”.)
■ Run Setup: Displays the Switch Setup screen for quickly configuring
basic switch parameters such as IP addressing, default gateway, logon
default interface, and others. (Refer to the Installation and Getting
Started Guide for your switch.)
■ Logout: Closes the Menu interface and console session, and disconnects
Telnet access to the switch. (See “How to End a Menu Session and Exit
from the Console” on page 3-5.)

Using the Menu Interface
Screen Structure and Navigation
Screen Structure and Navigation
Menu interface screens include these three elements:
■ Parameter fields and/or read-only information such as statistics
■ Navigation and configuration actions, such as Save, Edit, and Cancel
■ Help line to describe navigation options, individual parameters, and read-
only data
For example, in the following System Information screen:
Help line

“Forms” Design. The configuration screens, in particular, operate similarly
to a number of PC applications that use forms for data entry. When you first
enter these screens, you see the current configuration for the item you have
selected. To change the configuration, the basic operation is to:
1. Press [E] to select the Edit action.
2. Navigate through the screen making all the necessary configuration
changes. (See Table 3-5 on page 3-10.)
3. Press [Enter] to return to the Actions line. From there you can save the
configuration changes or cancel the changes. Cancel returns the configu-
ration to the values you saw when you first entered the screen.

Task: Actions:
Execute an action
from the “Actions –>”
list at the bottom of
the screen:
Use either of the following methods:
• Use the arrow keys ([<], or [>]) to highlight the action you want
to execute, then press [Enter].
• Press the key corresponding to the capital letter in the action
name. For example, in a configuration menu, press [E] to select
Edit and begin editing parameter values.
Reconfigure (edit) a
parameter setting or a
field:
1. Select a configuration item, such as System Name. (See figure
3-4.)
2. Press [E] (for Edit on the Actions line).
3. Use [Tab] or the arrow keys ([<], [>], [^], or [v]) to highlight the
item or field.
4. Do one of the following:
– If the parameter has preconfigured values, either use the
Space bar to select a new option or type the first part of your
selection and the rest of the selection appears
automatically. (The help line instructs you to “Select” a
value.)
– If there are no preconfigured values, type in a value (the Help
line instructs you to “Enter” a value).
5. If you want to change another parameter value, return to step 3.
6. If you are finished editing parameters in the displayed screen,
press [Enter] to return to the Actions line and do one of the
following:
– To save and activate configuration changes, press [S] (for the
Save action). This saves the changes in the startup
configuration and also implements the change in the
currently running configuration. (See Chapter 6, “Switch
Memory and Configuration”.)
– To exit from the screen without saving any changes that you
have made (or if you have not made changes), press [C] (for
the Cancel action).
Note: In the menu interface, executing Save activates most
parameter changes and saves them in the startup configuration
(or flash) memory, and it is therefore not necessary to reboot the
switch after making these changes. But if an asterisk appears
next to any menu item you reconfigure, the switch will not
activate or save the change for that item until you reboot the
switch. In this case, rebooting should be done after you have
made all desired changes and then returned to the Main Menu.
7. When you finish editing parameters, return to the Main Menu.
8. If necessary, reboot the switch by highlighting Reboot Switch
in the Main Menu and pressing [Enter]. (See the Note, above.)

If you make configuration changes in the menu interface that require a reboot,
the switch displays an asterisk (*) next to the menu item in which the change
has been made. For example, if you change and save the value for the Maximum
VLANs to support parameter, an asterisk appears next to the VLAN Support entry
in the VLAN Menu screen, and also next to the Switch Configuration entry in
the Main Menu.
Reminder to
reboot the
switch to
activate
configuration
changes.
Asterisk
indicates a
configuration
change that
requires a
reboot in order
to take effect.
Figure 3-8. Indication of a Configuration Change Requiring a Reboot
To activate changes indicated by the asterisk, go to the Main Menu and select
the Reboot Switch option.
Note Executing the write memory command in the CLI does not affect pending
configuration changes indicated by an asterisk in the menu interface. That is,
only a reboot from the menu interface or a boot or reload command from the
CLI will activate a pending configuration change indicated by an asterisk.

Using the Command Line Interface (CLI)
Overview
Overview
The CLI is a text-based command interface for configuring and monitoring the
switch. The CLI gives you access to the switch’s full set of commands while
providing the same password protection that is used in the web browser
interface and the menu interface.
Accessing the CLI
Like the menu interface, the CLI is accessed through the switch console, and
in the switch’s factory default state, is the default interface when you start a
console session. You can access the console out-of-band by directly connect-
ing a terminal device to the switch, or in-band by using Telnet either from a
terminal device or through the web browser interface.
Also, if you are using the menu interface, you can access the CLI by selecting
the Command Line (CLI) option in the Main Menu.
Using the CLI
The CLI offers these privilege levels to help protect the switch from unauthor-
ized access:
1. Operator
2. Manager
3. Global Configuration
4. Context Configuration
Note CLI commands are not case-sensitive.
4-2
Using the Command Line Interface (CLI)
Using the CLI
When you use the CLI to make a configuration change, the switch writes the
change to the Running-Config file in volatile memory. This allows you to test
your configuration changes before making them permanent. To make changes
permanent, you must use the write memory command to save them to the
Startup-Config file in non-volatile memory. If you reboot the switch without
first using write memory, all changes made since the last reboot or write memory
(whichever is later) will be lost. For more on switch memory and saving
configuration changes, see Chapter 6, “Switch Memory and Configuration”.
Privilege Levels at Logon
Privilege levels control the type of access to the CLI. To implement this
control, you must set at least a Manager password. Without a Manager
password configured, anyone having serial port, Telnet, or web browser
access to the switch can reach all CLI levels. (For more on setting passwords,
refer to the chapter on usernames and passwords in the Access Security Guide
for your switch.)
When you use the CLI to log on to the switch, and passwords are set, you will
be prompted to enter a password. For example:
Password Prompt
Figure 4-1. Example of CLI Log-On Screen with Password(s) Set
In the above case, you will enter the CLI at the level corresponding to the
password you provide (operator or manager).
If no passwords are set when you log onto the CLI, you will enter at the
Manager level. For example:
ProCurve# _
4-3
Using the Command Line Interface (CLI)
Using the CLI
Caution ProCurve strongly recommends that you configure a Manager password. If a
Manager password is not configured, then the Manager level is not password-
protected, and anyone having in-band or out-of-band access to the switch may
be able to reach the Manager level and compromise switch and network
security. Note that configuring only an Operator password does not prevent
access to the Manager level by intruders who have the Operator password.
Pressing the Clear button on the front of the switch removes password
protection. For this reason, it is recommended that you protect the switch
from physical access by unauthorized persons. If you are concerned about
switch security and operation, you should install the switch in a secure
location, such as a locked wiring closet.

4. Context Configuration Level
Figure 4-2. Access Sequence for Privilege Levels
Operator Privileges
At the Operator level you can examine the current configuration and move
between interfaces without being able to change the configuration. A “>”
character delimits the Operator-level prompt. For example:
ProCurve> _ (Example of the Operator prompt.)
When using enable to move to the Manager level, the switch prompts you for
the Manager password if one has already been configured.
4-4
Using the Command Line Interface (CLI)
Using the CLI
Manager Privileges
Manager privileges give you three additional levels of access: Manager, Global
Configuration, and Context Configuration. A “#” character delimits any Man-
ager prompt. For example:
ProCurve#_ Example of the Manager prompt.
■ Manager level: Provides all Operator level privileges plus the ability to
perform system-level actions that do not require saving changes to the
system configuration file. The prompt for the Manager level contains only
the system name and the “#” delimiter, as shown above. To select this
level, enter the enable command at the Operator prompt and enter the
Manager password, when prompted. For example:
ProCurve> enable Enter enable at the Operator prompt.
Password: CLI prompt for the Manager password.
ProCurve# _ The Manager prompt appears after the
correct Manager password is entered.
■ Global Configuration level: Provides all Operator and Manager level
privileges, and enables you to make configuration changes to any of the
switch’s software features. The prompt for the Global Configuration level
includes the system name and “(config)”. To select this level, enter the
config command at the Manager prompt. For example:
ProCurve# config Enter config at the Manager prompt.
ProCurve(config)#_ The Global Config prompt.
■ Context Configuration level: Provides all Operator and Manager priv-
ileges, and enables you to make configuration changes in a specific
context, such as one or more ports or a VLAN. The prompt for the Context
Configuration level includes the system name and the selected context.
For example:
ProCurve(eth-1)#
ProCurve(vlan-10)#
The Context level is useful, for example, for executing several commands
directed at the same port or VLAN, or if you want to shorten the command
strings for a specific context area. To select this level, enter the specific
context at the Global Configuration level prompt. For example, to select
the context level for an existing VLAN with the VLAN ID of 10, you would
enter the following command and see the indicated result:
ProCurve(config)# vlan 10
ProCurve(vlan-10)#

Moving Between the CLI and the Menu Interface. When moving
between interfaces, the switch retains the current privilege level (Manager or
Operator). That is, if you are at the Operator level in the menu and select the
Command Line Interface (CLI) option from the Main Menu, the CLI prompt
appears at the Operator level.
Changing Parameter Settings. Regardless of which interface is used (CLI,
menu interface, or web browser interface), the most recently configured
version of a parameter setting overrides any earlier settings for that parameter.
4-7
Using the Command Line Interface (CLI)
Using the CLI
For example, if you use the menu interface to configure an IP address of “X”
for VLAN 1 and later use the CLI to configure a different IP address of “Y” for
VLAN 1, then “Y” replaces “X” as the IP address for VLAN 1 in the running-
config file. If you subsequently execute write memory in the CLI, then the
switch also stores “Y” as the IP address for VLAN 1 in the startup-config file.
(For more on the startup-config and running config files, see Chapter 6,
“Switch Memory and Configuration”.)
Listing Commands and Command Options
At any privilege level you can:
■ List all of the commands available at that level
■ List the options for a specific command
Listing Commands Available at Any Privilege Level
At a given privilege level you can list and execute the commands that level
offers, plus all of the commands available at preceding levels. For example,
at the Operator level, you can list and execute only the Operator level com-
mands. However, at the Manager level, you can list and execute the commands
available at both the Operator and Manager levels.
Type “?” To List Available Commands. 1.Typing the ? symbol lists the
commands you can execute at the current privilege level. For example,
typing ? at the Operator level produces this listing:
Figure 4-3. Example of the Operator Level Command Listing
4-8
Using the Command Line Interface (CLI)
Using the CLI
Typing ? at the Manager level produces this listing:
When - - MORE - - appears, use the Space
bar or [Return] to list additional commands.
Figure 4-4.Example of the Manager-Level Command Listing
When - - MORE - - appears, there are more commands in the listing. To list the
next screenfull of commands, press the Space bar. To list the remaining
commands one-by-one, repeatedly press [Enter].
Typing ? at the Global Configuration level or the Context Configuration level
produces similar results.
Use [Tab] To Search for or Complete a Command Word. You can use
[Tab] to help you find CLI commands or to quickly complete the current word
in a command. To do so, type one or more consecutive characters in a
command and then press [Tab] (with no spaces allowed). For example, at the
Global Configuration level, if you press [Tab] immediately after typing “t”, the
CLI displays the available command options that begin with “t”. For example:
ProCurve(config)# t [Tab]
tacacs-server
telnet-server
time
timesync
trunk
telnet
terminal
traceroute
ProCurve(config)# t
4-9
Using the Command Line Interface (CLI)
Using the CLI
As mentioned above, if you type part of a command word and press [Tab], the
CLI completes the current word (if you have typed enough of the word for the
CLI to distinguish it from other possibilities), including hyphenated exten-
sions. For example:
ProCurve(config)# port-[Tab]
ProCurve(config)# port-security _
Pressing [Tab] after a completed command word lists the further options for
that command.
ProCurve(config)# qos [Tab]
udp-portSet UDP port based priority.
tcp-portSet TCP port based priority.
device-priorityConfigure device-based priority.
dscp-mapDefine mapping between a DSCP
(Differentiated-Services Codepoint)
value and 802.1p priority.
type-of-serviceConfigure the Type-of-Service
method the device uses to
prioritize IP traffic.
Listing Command Options
You can use the CLI to remind you of the options available for a command by
entering command keywords followed by ?. For example, suppose you want
to see the command options for configuring the console settings:
This example displays the command options
for configuring the switch’s console settings.

Using the CLI
Displaying CLI “Help”
CLI Help provides two types of context-sensitive information:
■ Command list with a brief summary of each command’s purpose
■ Detailed information on how to use individual commands
Displaying Command-List Help.
Syntax: help
Displays a listing of command Help summaries for all
commands available at the current privilege level. That is, at
the Operator level, executing help displays the Help summaries
only for Operator-Level commands. At the Manager level,
executing help displays the Help summaries for both the
Operator and Manager levels, and so on.
For example, to list the Operator-Level commands with their purposes:
Figure 4-6. Example of Context-Sensitive Command-List Help
Displaying Help for an Individual Command.
Syntax: < command-string > help
This option displays Help for any command available at the
current context level.
For example, to list the Help for the interface command in the Global Config-
uration privilege level:
4-11
Using the Command Line Interface (CLI)
Using the CLI
Figure 4-7.Example of How To Display Help for a Specific Command
Note that trying to list the help for an individual command from a privilege
level that does not include that command results in an error message. For
example, trying to list the help for the interface command while at the global
configuration level produces this result:
ProCurve# speed-duplex help
Invalid input: speed-duplex

Using the Command Line Interface (CLI)
Using the CLI
Configuration Commands and the Context
Configuration Modes
You can execute any configuration command in the global configuration mode
or in selected context modes. However, using a context mode enables you to
execute context-specific commands faster, with shorter command strings.
The switch offers interface (port or trunk group) and VLAN context configu-
ration modes:
Port or Trunk-Group Context. Includes port- or trunk-specific commands
that apply only to the selected port(s) or trunk group, plus the global config-
uration, Manager, and Operator commands. The prompt for this mode
includes the identity of the selected port(s):
ProCurve(config)# interface c3-c6
ProCurve(eth-C5-C8)#
ProCurve(config)# interface trk1
ProCurve(eth-Trk1)#
Commands executed at configuration level for entering port and
trk1 static trunk-group contexts, and resulting prompts showing
port or static trunk contexts..
ProCurve(eth-C5-C8)#
ProCurve(eth-Trk1)#
ProCurve(eth-C5-C8)# ?
ProCurve(eth-C5-C8)# ?
Lists the commands you can use in the port or static trunk context,
plus the Manager, Operator, and context commands you can exe-
cute at this level.
4-13
Using the Command Line Interface (CLI)
Using the CLI
In the port context, the first block of commands in the “?”
listing show the context-specific commands that will affect
only ports C3-C6.
The remaining commands in the listing are Manager,
Operator, and context commands.

Using the Command Line Interface (CLI)
Using the CLI
VLAN Context . Includes VLAN-specific commands that apply only to the
selected VLAN, plus Manager and Operator commands. The prompt for this
mode includes the VLAN ID of the selected VLAN. For example, if you had
already configured a VLAN with an ID of 100 in the switch:
ProCurve(config)# vlan 100
Command executed at configuration level to enter VLAN 100 context.
ProCurve(vlan-100)#
Resulting prompt showing VLAN 100 context.
ProCurve(vlan-100)# ?
Lists commands you can use in the VLAN context, plus Manager,
Operator, and context commands you can execute at this level.
In the VLAN
context, the
first block of
commands in
the “?” listing
show the
commands that
will affect only
vlan-100.
The remaining
commands in

Using a Command Alias
You can create a simple command alias to use in place of a command name
and its options. Choose an alias name that is not an existing CLI command
already. Existing CLI commands are searched before looking for an alias
command; an alias that is identical to an existing command will not be
executed.
The alias command is executed from the current configuration context (oper-
ator, manager, or global). If the command that is aliased has to be executed in
the global configuration context, you must execute the alias for that command
in the global configuration context as well. This prevents bypassing the
security in place for a particular context.
ProCurve recommends that you configure no more than 128 aliases.
Syntax: [no] alias <name> <command>
Creates a shortcut alias name to use in place of a commonly
used command. The alias command is executed from the
current config context.
name: Specifies the new command name to use to simplify
keystrokes and aid memory.
command: Specifies an existing command to be aliased. The
command must be enclosed in quotes.
Use the no form of the command to remove the alias.
For example, if you use the show interface custom command to specify the
output, you can configure an alias for the command to simplify execution. It
is recommended that you use an alias that does not have an existing tab
completion in the CLI. For example, using an alias that starts with “show” or
“int” would complete to “show” and “interface” respectively when you use the
tab completion function.

Note Remember to enclose the command being aliased in quotes.
Command parameters for the aliased command can be added at the end of the
alias command string. For example:

Using the ProCurve Web Browser Interface
Starting a Web Browser Interface Session with the Switch
Starting a Web Browser
Interface Session with the Switch
You can start a web browser session in the following ways:
■ Using a standalone web browser on a network connection from a PC or
UNIX workstation:
• Directly connected to your network
• Connected through remote access to your network
■ Using a network management station running ProCurve Manager on your
network
Using a Standalone Web Browser in a PC or UNIX
Workstation
This procedure assumes that you are using a compatible web browser and that
the switch is configured with an IP address accessible from your PC or
workstation. (For more on assigning an IP address, refer to “IP Configuration”
on page 8-2.)
1. Ensure that the JavaTM applets are enabled for your browser. For more
information on this topic, refer to your browser’s online Help.
2. Use the web browser to access the switch. If your network includes a
Domain Name Server (DNS), your switch’s IP address may have a name
associated with it (for example, switch8212) that you can type in the
Location or Address field instead of the IP address. Using DNS names
typically improves browser performance. Contact your network adminis-
trator to enquire about DNS names associated with your ProCurve switch.
Type the IP address (or DNS name) of the switch in the browser Location
or Address (URL) field and press [Enter]. (It is not necessary to include
http://.)
switch5308 [Enter] (example of a DNS-type name)

Using the ProCurve Web Browser Interface
Starting a Web Browser Interface Session with the Switch
Using ProCurve Manager (PCM) or
ProCurve Manager Plus (PCM+)
ProCurve Manager and ProCurve Manager Plus are designed for installation
on a network management workstation. For this reason, the system require-
ments are different from the system requirements for accessing the switch’s
web browser interface from a non-management PC or workstation. For PCM
and PCM+ requirements, refer to the information provided with the software.
This procedure assumes that:
■ You have installed the recommended web browser on a PC or workstation
that serves as your network management station.
■ The networked device you want to access has been assigned an IP address
and (optionally) a DNS name, and has been discovered by PCM or PCM+.
(For more on assigning an IP address, refer to “IP Configuration” on page
8-2.)
To establish a web browser session with PCM or PCM+ running, do the
following on the network management station:
1. Make sure the JavaTM applets are enabled for your web browser. If they
are not, refer to the web browser online Help for specific information on
enabling the Java applets.
2. In the Interconnected Devices listing under Network Manager Home (in the
PCM/PCM+ sidebar), right-click on the model number of the device you
want to access.
3. The web browser interface automatically starts with the Status Overview
window displayed for the selected device, as shown in Figure 5-1.
Note If the Registration window appears, click on the Status tab.

Tasks for Your First ProCurve Web Browser Interface Session
Tasks for Your First ProCurve Web
Browser Interface Session
The first time you access the web browser interface, there are three tasks you
should perform:
■ Review the “First Time Install” window
■ Set Manager and Operator passwords
■ Set access to the web browser interface online help
Viewing the “First Time Install” Window
When you access the switch’s web browser interface for the first time, the
Alert log contains a “First Time Install” alert, as shown in figure 5-2. This gives
you information about first time installations, and provides an immediate
opportunity to set passwords for security and to specify a Fault Detection
policy, which determines the types of messages that will be displayed in the
Alert Log.
Double click on First Time Install in the Alert log (figure 5-1 on page 5-6). The
web browser interface then displays the “First Time Install” window, below.
Figure 5-2. First-Time Install Window

Using the ProCurve Web Browser Interface
Tasks for Your First ProCurve Web Browser Interface Session
This window is the launching point for the basic configuration you need to
perform to set web browser interface passwords for maintaining security and
a fault detection policy, which determines the types of messages that the Alert
Log displays.
To set web browser interface passwords, click on secure access to the device
to display the Device Passwords screen, and then go to the next page. (You
can also access the password screen by clicking on the Security tab.)
To set Fault Detection policy, click on select the fault detection configuration in
the second bullet in the window and go to the section, “Setting Fault Detection
Policy” on page 5-23. (You can also access the password screen by clicking on
the Configuration tab, and then the [Fault Detection] key.)
Security: Creating Usernames and Passwords
in the Browser Interface
Note On the switches covered in this guide you can also configure RADIUS authen-
tication for web browser interface access. For more information, refer to the
chapter titled “RADIUS Authentication and Accounting” in the Access Secu-
rity Guide for your switch.
You may want to create both a username and a password to create access
security for your switch. There are two levels of access to the interface that
can be controlled by setting user names and passwords:
■ Operator Setting. An Operator-level user name and password allows
read-only access to most of the web browser interface, but prevents
access to the Security window.
■ Manager Setting. A Manager-level user name and password allows full
read/write access to the web browser interface.
5-8

Tasks for Your First ProCurve Web Browser Interface Session
Figure 5-3.The Device Passwords Window
To set the passwords:
1. Access the Device Passwords screen by one of the following methods:
• If the Alert Log includes a “First Time Install” event entry, double
click on this event, then, in the resulting display, click on the
secure access to the device link.
• Select the Security tab.
2. Click in the appropriate box in the Device Passwords window and enter
user names and passwords. You will be required to repeat the password
strings in the confirmation boxes.
Both the user names and passwords can be up to 16 printable ASCII
characters.
3. Click on [Apply Changes] to activate the user names and passwords.
Note Passwords you assign in the web browser interface will overwrite previous
passwords assigned in either the web browser interface, the CLI, or the menu
interface. That is, the most recently assigned passwords are the switch’s
passwords, regardless of which interface was used to assign the string.
5-9
Using the ProCurve Web Browser Interface
Tasks for Your First ProCurve Web Browser Interface Session
Entering a User Name and Password
Figure 5-4. Example of the Password Prompt in the Web Browser Interface
The manager and operator passwords are used to control access to all switch
interfaces. Once set, you will be prompted to supply the password every time
you try to access the switch through any of its interfaces. The password you
enter determines the capability you have during that session:
■ Entering the manager password gives you full read/write/troubleshooting
capabilities
■ Entering the operator password gives you read and limited trouble-
shooting capabilities.
Using a User Name
If you also set user names in the web browser interface screen, you must
supply the correct user name for web browser interface access. If a user name
has not been set, then leave the User Name field in the password window
blank.
Note that the Command Prompt and switch console interfaces use only the
password, and do not prompt you for the User Name.
If You Lose the Password
If you lose the passwords, you can clear them by pressing the Clear button on
the front of the switch. This action deletes all password and user name
protection from all of the switch’s interfaces.
5-10
Using the ProCurve Web Browser Interface
Tasks for Your First ProCurve Web Browser Interface Session
The Clear button is provided for your convenience, but its presence means
that if you are concerned with the security of the switch configuration and
operation, you should make sure the switch is installed in a secure location,
such as a locked wiring closet. (For more information, refer to “Front Panel
Security” in the chapter titled “Configuring Username and Password Secu-
rity” in the Access Security Guide for your switch.)
Online Help for the Web Browser Interface
Online Help is available for the web browser interface. You can use it by
clicking on the Help text in the top right corner of any of the web browser
interface screens.

Support URL
This is the site the switch accesses when you click on the Support tab on the
web browser interface. The default URL is:
www.procurve.com
which is the World Wide Web site for ProCurve networking products. Click on
technical support on that page to get support information regarding your
switch, including white papers, software updates, and more.
As an alternative, you can replace the ProCurve URL with the URL for a local
site used for logging reports on network performance or other support activ-
ities.
Help and the Management Server URL
The Management Server URL field specifies the URL the switch uses to find
online Help for the web browser interface.
■ If you install PCM (ProCurve Manager) in your network, the PCM manage-
ment station acts as the web browser Help server for the switch and
automatically inserts the necessary URL in this field. For more on the
option, see “Using the PCM Server for Switch Web Help” on page 5-14.)
■ In the default configuration (and if PCM is not running on your network)
this field is set to the URL for accessing online Help from the ProCurve
Networking web site:
www.hp.com/rnd/device_help
Using this option, the Help files are automatically available if your work-
station can access the World Wide Web. In this case, if Online Help fails
to operate, ensure that the above URL appears in the Management Server
URL field shown in Figure 5-7:

Legend
Figure 5-9. The Graphs Area
Port Utilization
The Port Utilization bar graphs show the network traffic on the port with a
breakdown of the packet types that have been detected (unicast packets, non-
unicast packets, and error packets). The Legend identifies traffic types and
their associated colors on the bar graph:
■ % Unicast Rx & All Tx: This is all unicast traffic received and all
transmitted traffic of any type. This indicator (a blue color on many
systems) can signify either transmitted or received traffic.
■ % Non-Unicast Pkts Rx: All multicast and broadcast traffic received by
the port. This indicator (a gold color on many systems) enables you to
know “at-a-glance” the source of any non-unicast traffic that is causing
high utilization of the switch. For example, if one port is receiving heavy
broadcast or multicast traffic, all ports will become highly utilized. By
color-coding the received broadcast and multicast utilization, the bar
graph quickly and easily identifies the offending port. This makes it faster
and easier to discover the exact source of the heavy traffic because you
don’t have to examine port counter data from several ports.
■ % Error Pkts Rx: All error packets received by the port. (This indicator
is a reddish color on many systems.) Although errors received on a port
are not propagated to the rest of the network, a consistently high number
of errors on a specific port may indicate a problem on the device or
network segment connected to the indicated port.
5-17
Using the ProCurve Web Browser Interface
Status Reporting Features
■ Maximum Activity Indicator: As the bars in the graph area change
height to reflect the level of network activity on the corresponding port,
they leave an outline to identify the maximum activity level that has been
observed on the port.
Utilization Guideline. A network utilization of 40% is considered the
maximum that a typical Ethernet-type network can experience before encoun-
tering performance difficulties. If you observe utilization that is consistently
higher than 40% on any port, click on the Port Counters button to get a detailed
set of counters for the port.
To change the amount of bandwidth the Port Utilization bar graph
shows. Click on the bandwidth display control button in the upper left corner
of the graph. (The button shows the current scale setting, such as 40%.) In the
resulting menu, select the bandwidth scale you want the graph to show (3%,
10%, 25%, 40%, 75%, or 100%), as shown in figure figure 5-10.
Note that when viewing activity on a gigabit port, you may want to select a
lower value (such as 3% or 10%). This is because the bandwidth utilization of
current network applications on gigabit links is typically minimal, and may
not appear on the graph if the scale is set to show high bandwidth utilization.

Port Status Indicators Legend
Figure 5-12. The Port Status Indicators and Legend
The Port Status indicators show a symbol for each port that indicates the
general status of the port. There are four possible statuses:
■ Port Connected – the port is enabled and is properly connected to an
active network device.
■ Port Not Connected – the port is enabled but is not connected to an
active network device. A cable may not be connected to the port, or the
device at the other end may be powered off or inoperable, or the cable or
connected device could be faulty.
■ Port Disabled – the port has been configured as disabled through the
web browser interface, the switch console, or SNMP network manage-
ment.
■ Port Fault-Disabled – a fault condition has occurred on the port that
has caused it to be auto-disabled. Note that the Port Fault-Disabled
symbol will be displayed in the legend only if one or more of the ports is
in that status. See Appendix B, “Monitoring and Analyzing Switch Opera-
tion” for more information.

Using the ProCurve Web Browser Interface
Status Reporting Features
The Alert Log
The web browser interface Alert Log, shown in the lower half of the screen,
shows a list of network occurrences, or alerts, that were detected by the
switch. Typical alerts are Broadcast Storm, indicating an excessive number of
broadcasts received on a port, and Problem Cable, indicating a faulty cable. A
full list of alerts is shown in the table on page 5-21.
Figure 5-13. Example of the Alert Log
Each alert has the following fields of information:
■ Status – The level of severity of the event generated. Severity levels can
be Information, Normal, Warning, and Critical. If the alert is new (has not
yet been acknowledged), the New symbol is also in the Status column.
■ Alert – The specific event identification.
■ Date/Time – The date and time the event was received by the web
browser interface. This value is shown in the format: DD-MM-YY
HH:MM:SS AM/PM, for example, 16-Sep-99 7:58:44 AM.
■ Description – A short narrative statement that describes the event. For
example, Excessive CRC/Alignment errors on port: 8.
Sorting the Alert Log Entries
The alerts are sorted, by default, by the Date/Time field with the most recent
alert listed at the top of the list. The second most recent alert is displayed
below the top alert and so on. If alerts occurred at the same time, the
simultaneous alerts are sorted by order in which they appear in the MIB.
Bold characters in a column heading indicate that the alert field alert log
entries. You can sort by any of the other columns by clicking on the column
heading. The Alert and Description columns are sorted alphabetically, while the
Status column is sorted by severity type, with more critical severity indicators
appearing above less critical indicators.

Alert Types and Detailed Views
As of June, 2007, the web browser interface generates the following alert
types:
• Auto Partition • High collision or drop rate
• Backup Transition • Loss of Link
• Excessive broadcasts • Mis-Configured SQE
• Excessive CRC/alignment errors • Network Loop
• Excessive jabbering • Polarity Reversal
• Excessive late collisions • Security Violation
• First Time Install • Stuck 10BaseT Port
• Full-Duplex Mismatch • Too many undersized (runt)/giant
• Half-Duplex Mismatch packets
• Transceiver Hot Swap
Note When troubleshooting the sources of alerts, it may be helpful to check the
switch’s Port Status and Port Counter windows, or use the CLI or menu
interface to view the switch’s Event Log.
When you double click on an Alert Entry, the web browser interface displays
a separate window showing information about the event. This view includes
a description of the problem and a possible solution. It also provides three
management buttons:
■ Acknowledge Event – removes the New symbol from the log entry
■ Delete Event – removes the alert from the Alert Log
■ Cancel – closes the detail view with no change to the status of the alert
and returns you to the Overview screen.
For example, figure 5-14 shows a sample detail view describing an Excessive
CRC/Alignment Error alert.

Setting Fault Detection Policy
One of the powerful features in the web browser interface is the Fault
Detection facility. For your switch, this feature controls the types of alerts
reported to the Alert Log based on their level of severity.
Set this policy in the Fault Detection window (figure 5-15).
Figure 5-15. The Fault Detection Window
The Fault Detection screen contains a list box for setting fault detection and
response policy, and enables you to set the sensitivity level at which a network
problem should generate an alert and send it to the Alert Log.
5-23
Using the ProCurve Web Browser Interface
Status Reporting Features
To provide the most information on network problems in the Alert Log, the
recommended sensitivity level for Log Network Problems is High Sensitivity. The
Fault Detection settings are:
■ High Sensitivity. This policy directs the switch to send all alerts to the
Alert Log. This setting is most effective on networks that have none or
few problems.
■ Medium Sensitivity. This policy directs the switch to send alerts related
to network problems to the Alert Log. If you want to be notified of
problems which cause a noticeable slowdown on the network, use this
setting.
■ Low Sensitivity. This policy directs the switch to send only the most
severe alerts to the Alert Log. This policy is most effective on a network
where there are normally a lot of problems and you want to be informed
of only the most severe ones.
■ Never. Disables the Alert Log and transmission of alerts (traps) to the
management server (in cases where a network management tool such as
ProCurve Manager is in use). Use this option when you don’t want to use
the Alert Log.
The Fault Detection Window also contains three Change Control Buttons:
■ Apply Changes. This button stores the settings you have selected for all
future sessions with the web browser interface until you decide to change
them.
■ Clear Changes. This button removes your settings and returns the
settings for the list box to the level it was at in the last saved detection-
setting session.
■ Reset to Default Settings. This button reverts the policy setting to
Medium Sensitivity for Log Network Problems.

Switch Memory and Configuration
Overview
Overview
This chapter describes:
■ How switch memory manages configuration changes
■ How the CLI implements configuration changes
■ How the menu interface and web browser interface implement configu-
ration changes
■ How the switch provides software options through primary/secondary
flash images
■ How to use the switch’s primary and secondary flash options, including
displaying flash information, booting or restarting the switch, and other
topics
Configuration File Management
The switch maintains two configuration files, the running-config file and the
startup-config file.
Volatile Memory
Running-Config File
(Controls switch operation. When the switch boots, the
contents of this file are erased and replaced by the
contents of the startup-config file.)
Flash (Non-Volatile) Memory
Startup-Config File
(Preserves the most recently saved configuration
through any subsequent reboot.)
CLI configuration
changes are written to
this file. To use the CLI to
save the latest version of
this file to the startup-
config file, you must
execute the write
memory command.
Menu interface configu-
ration changes are simul-
taneously written to both
of these files.
Figure 6-1. Conceptual Illustration of Switch Memory Operation
6-3
Switch Memory and Configuration
Configuration File Management
■ Running Config File: Exists in volatile memory and controls switch
operation. If no configuration changes have been made in the CLI since
the switch was last booted, the running-config file is identical to the
startup-config file.
■ Startup-config File: Exists in flash (non-volatile) memory and is used
to preserve the most recently-saved configuration as the “permanent”
configuration.
Booting the switch replaces the current running-config file with a new run-
ning-config file that is an exact copy of the current startup-config file.
Note Any of the following actions boots the switch:
• Executing the boot or the reload command in the CLI
• Executing the boot command in the menu interface
• Pressing the Reset button on the front of the switch
• Removing, then restoring power to the switch
For more on reboots and the switch’s dual-flash images, refer to “Using
Primary and Secondary Flash Image Options” on page 6-13.
Options for Saving a New Configuration. Making one or more changes
to the running-config file creates a new operating configuration. Saving a new
configuration means to overwrite (replace) the current startup-config file with
the current running-config file. This means that if the switch subsequently
reboots for any reason, it will resume operation using the new configuration
instead of the configuration previously defined in the startup-config file. There
are three ways to save a new configuration:
■ In the CLI: Use the write memory command. This overwrites the current
startup-config file with the contents of the current running-config file.
■ In the menu interface: Use the Save command. This overwrites both the
running-config file and the startup-config file with the changes you have
specified in the menu interface screen.
■ In the web browser interface: Use the [Apply Changes] button or other
appropriate button. This overwrites both the running-config file and the
startup-config file with the changes you have specified in the web browser
interface window.
Note that using the CLI instead of the menu or web browser interface gives
you the option of changing the running configuration without affecting the
startup configuration. This allows you to test the change without making it
6-4
Switch Memory and Configuration
Configuration File Management
“permanent”. When you are satisfied that the change is satisfactory, you can
make it permanent by executing the write memory command. For example,
suppose you use the following command to disable port 5:
ProCurve(config)# interface ethernet 5 disable
The above command disables port 5 in the running-config file, but not in the
startup-config file. Port 5 remains disabled only until the switch reboots. If
you want port 5 to remain disabled through the next reboot, use write memory
to save the current running-config file to the startup-config file in flash
memory.
ProCurve(config)# write memory
If you use the CLI to make a configuration change and then change from the
CLI to the Menu interface without first using write memory to save the change
to the startup-config file, then the switch prompts you to save the change. For
example, if you use the CLI to create VLAN 20, and then select the menu
interface, VLAN 20 is configured in the running-config file, but not in the
startup-config file. In this case you will see:
ProCurve(config)# vlan 20
ProCurve(config)# menu
Do you want to save current configuration [y/n]?
If you type [Y], the switch overwrites the startup-config file with the running-
config file, and your configuration change(s) will be preserved across reboots.
If you type [N], your configuration change(s) will remain only in the running-
config file. In this case, if you do not subsequently save the running-config file,
your unsaved configuration changes will be lost if the switch reboots for any
reason.
Storing and Retrieving Configuration Files. You can store or retrieve a
backup copy of the startup-config file on another device. For more
information, refer to the section on “Transferring Switch Configurations” on
page A-23 in Appendix A on “File Transfers”.

Switch Memory and Configuration
Using the CLI To Implement Configuration Changes
Using the CLI To Implement
Configuration Changes
The CLI offers these capabilities:
■ Access to the full set of switch configuration features
■ The option of testing configuration changes before making them perma-
nent
How To Use the CLI To View the Current Configuration Files. Use
show commands to view the configuration for individual features, such as port
status or Spanning Tree Protocol. However, to view either the entire startup-
config file or the entire running-config file, use the following commands:
■ show config — Displays a listing of the current startup-config file.
■ show running-config — Displays a listing of the current running-config file.
■ write terminal — Displays a listing of the current running-config file.
■ show config status — Compares the startup-config file to the running-
config file and lists one of the following results:
• If the two configurations are the same you will see:
– Running configuration is the same as the startup
configuration.
• If the two configurations are different, you will see:
– Running configuration has been changed and needs
to be saved.
Not e Show config, show running-config, and write terminal commands display the
configuration settings that differ from the switch’s factory-default configura-
tion.
How To Use the CLI To Reconfigure Switch Features. Use this proce-
dure to permanently change the switch configuration (that is, to enter a change
in the startup-config file).
1. Use the appropriate CLI commands to reconfigure the desired switch
parameters. This updates the selected parameters in the running-config
file.
2. Use the appropriate show commands to verify that you have correctly
made the desired changes.
6-6
Switch Memory and Configuration
Using the CLI To Implement Configuration Changes
3. Observe the switch’s performance with the new parameter settings to
verify the effect of your changes.
4. When you are satisfied that you have the correct parameter settings, use
the write memory command to copy the changes to the startup-config file.
Syntax: write memory
Saves the running configuration file to the startup-config.
The saved configuration becomes the boot-up configuration
of the switch on the next boot.
For example, the default port mode setting is auto. Suppose that your network
uses Cat 3 wiring and you want to connect the switch to another autosensing
device capable of 100 Mbps operation. Because 100 Mbps over Cat 3 wiring
can introduce transmission problems, the recommended port mode is auto-10,
which allows the port to negotiate full- or half-duplex, but restricts speed to
10 Mbps. The following command configures port A5 to auto-10 mode in the
running-config file, allowing you to observe performance on the link without
making the mode change permanent.
ProCurve(config)# interface e a5 speed-duplex auto-10
After you are satisfied that the link is operating properly, you can save the
change to the switch’s permanent configuration (the startup-config file) by
executing the following command:
ProCurve(config)# write memory
The new mode (auto-10) on port A5 is now saved in the startup-config file, and
the startup-config and running-config files are identical. If you subsequently
reboot the switch, the auto-10 mode configuration on port A5 will remain
because it is included in the startup-config file.
How To Cancel Changes You Have Made to the Running-Config File.
If you use the CLI to change parameter settings in the running-config file, and
then decide that you don’t want those changes to remain, you can use either
of the following methods to remove them:
■ Manually enter the earlier values you had for the changed settings. (This
is recommended if you want to restore a small number of parameter
settings to their previous boot-up values.)
■ Update the running-config file to match the startup-config file by reboot-
ing the switch. (This is recommended if you want to restore a larger
number of parameter settings to their previous boot-up values.)
6-7
Switch Memory and Configuration
Using the CLI To Implement Configuration Changes
If you use the CLI to change a parameter setting, and then execute the boot
command without first executing the write memory command to save the
change, the switch prompts you to specify whether to save the changes in the
current running-config file. For example:
ProCurve(config)# interface e 1 disable
Disables port 1 in the running configuration, which causes port 1 to block all traffic.
ProCurve(config)# boot
Device will be rebooted, do you want to continue [y/n]? y
Do you want to save current configuration [y/n]?
Press [Y] to continue the rebooting process.
You will then see this prompt.
Figure 6-2. Boot Prompt for an Unsaved Configuration
The above prompt means that one or more parameter settings in the running-
config file differ from their counterparts in the startup-config file and you need
to choose which config file to retain and which to discard.
■ If you want to update the startup-config file to match the running-config
file, press [Y] for “yes”. (This means that the changes you entered in the
running-config file will be saved in the startup-config file.)
■ If you want to discard the changes you made to the running-config file so
that it will match the startup-config file, then press [N] for “no”. (This
means that the switch will discard the changes you entered in the running-
config file and will update the running-config file to match the startup-
config file.)
Note If you use the CLI to make a change to the running-config file, you should
either use the write memory command or select the save option allowed during
a reboot (figure 6-6-2, above) to save the change to the startup-config file. That
is, if you use the CLI to change a parameter setting, but then reboot the switch
from either the CLI or the menu interface without first executing the write
memory command in the CLI, the current startup-config file will replace the
running-config file, and any changes in the running-config file will be lost.
Using the Save command in the menu interface does not save a change made
to the running config by the CLI unless you have also made a configuration
change in the menu interface. Also, the menu interface displays the current
running-config values. Thus, where a parameter setting is accessible from both
the CLI and the menu interface, if you change the setting in the CLI, the new
6-8
Switch Memory and Configuration
Using the Menu and Web Browser Interfaces To Implement Configuration Changes
value will appear in the menu interface display for that parameter. However,
as indicated above, unless you also make a configuration change in the
menu interface, only the write memory command in the CLI will actually save
the change to the startup-config file.
How To Reset the startup-config and running-config Files to the
Factory Default Configuration. This command reboots the switch,
replacing the contents of the current startup-config and running-config files
with the factory-default startup configuration.
Syntax: erase startup-config
For example:
ProCurve(config)# erase startup-config
Configuration will be deleted and device rebooted, continue [y/n]?
Figure 6-3. Example of erase startup-config Command
Press [y] to replace the current configuration with the factory default config-
uration and reboot the switch. Press [n] to retain the current configuration and
prevent a reboot.
Using the Menu and Web Browser
Interfaces To Implement Configuration
Changes
The menu and web browser interfaces offer these advantages:
■ Quick, easy menu or window access to a subset of switch configuration
features
■ Viewing several related configuration parameters in the same screen, with
their default and current settings
■ Immediately changing both the running-config file and the startup-config
file with a single command
6-9
Switch Memory and Configuration
Using the Menu and Web Browser Interfaces To Implement Configuration Changes
Menu: Implementing Configuration Changes
You can use the menu interface to simultaneously save and implement a subset
of switch configuration changes without having to reboot the switch. That is,
when you save a configuration change in the menu interface, you simultane-
ously change both the running-config file and the startup-config file.
Note The only exception to this operation are two VLAN-related parameter changes
that require a reboot—described under “Rebooting To Activate Configuration
Changes” on page 6-11.
Using Save and Cancel in the Menu Interface
For any configuration screen in the menu interface, the Save command:
1. Implements the changes in the running-config file
2. Saves your changes to the startup-config file
If you decide not to save and implement the changes in the screen, select
Cancel to discard them and continue switch operation with the current oper-
ation. For example, suppose you have made the changes shown below in the
System Information screen:
To save and
implement the
changes for all
parameters in this
screen, press the
[Enter] key, then
press [S] (for Save).
To cancel all
changes, press the
[Enter] key, then
press [C] (for Cancel)
Figure 6-4. Example of Pending Configuration Changes You Can Save or Cancel
Note If you reconfigure a parameter in the CLI and then go to the menu interface
without executing a write memory command, those changes are stored only in
the running configuration (even if you execute a Save operation in the menu
interface). If you then execute a switch boot command in the menu interface,
6-10
Switch Memory and Configuration
Using the Menu and Web Browser Interfaces To Implement Configuration Changes
the switch discards the configuration changes made while using the CLI. To
ensure that changes made while using the CLI are saved, execute write memory
in the CLI before rebooting the switch.
Rebooting from the Menu Interface
■ Terminates the current session and performs a reset of the operating
system
■ Activates any configuration changes that require a reboot
■ Resets statistical counters to zero
(Note that statistical counters can be reset to zero without rebooting the
switch.
To Reboot the switch, use the Reboot Switch option in the Main Menu. (Note
that the Reboot Switch option is not available if you log on in Operator mode;
that is, if you enter an Operator password instead of a manager password at
the password prompt.)

VLANs to support parameter, an asterisk appears next to the VLAN Support entry in
the VLAN Menu screen, and also next to the Switch Configuration … entry in the

That is, when you save a configuration change (in most cases, by clicking on
[Apply Changes] or [Apply Settings], you simultaneously change both the running-
config file and the startup-config file.
Note If you reconfigure a parameter in the CLI and then go to the browser interface
without executing a write memory command, those changes will be saved to
the startup-config file if you click on [Apply Changes] or [Apply Settings] in the web
browser interface.

Switch Memory and Configuration
Using Primary and Secondary Flash Image Options
Using Primary and Secondary Flash
Image Options
The switches covered in this guide feature two flash memory locations for
storing switch software image files:
■ Primary Flash: The default storage for a switch software image.
■ Secondary Flash: The additional storage for an alternate switch software
image.
With the Primary/Secondary flash option you can test a new image in your
system without having to replace a previously existing image. You can also
use the image options for troubleshooting. For example, you can copy a
problem image into Secondary flash for later analysis and place another,
proven image in Primary flash to run your system. The switch can use only
one image at a time.
The following tasks involve primary/secondary flash options:
■ Displaying the current flash image data and determining which switch
software versions are available
■ Switch software downloads
■ Replacing and removing (erasing) a local switch software version
■ System booting
Displaying the Current Flash Image Data
Use the commands in this section to:
■ Determine whether there are flash images in both primary and secondary
flash
■ Determine whether the images in primary and secondary flash are the
same
■ Identify which switch software version is currently running
Viewing the Currently Active Flash Image Version. This command
identifies the software version on which the switch is currently running, and
whether the active version was booted from the primary or secondary flash
image.
Syntax: show version

Figure 6-7. Example Showing the Identity of the Current Flash Image
Determining Whether the Flash Images Are Different Versions. If the
flash image sizes in primary and secondary are the same, then in almost every
case, the primary and secondary images are identical. This command provides
a comparison of flash image sizes, plus the boot ROM version and from which
flash image the switch booted. For example, in the following case, the images
are different versions of the switch software, and the switch is running on the
version stored in the secondary flash image:
ProCurve(config)# show flash
Image Size(Bytes) Date Version Build #
Primary Image : 7493854 03/21/07 W.14.29 1617
Secondary Image : 7463821 03/23/07 W.14.30 1700
Boot Rom Version: W.14.01
Default Boot : Primary Will boot from primary flash
on the next boot.
Figure 6-8. Example Showing Different Flash Image Versions
Determining Which Flash Image Versions Are Installed. The show ver-
sion command displays which software version the switch is currently running
and whether that version booted from primary or secondary flash. Thus, if the
switch booted from primary flash, you will see the version number of the
software version stored in primary flash, and if the switch booted from
secondary flash, you will see the version number of the software version
stored in secondary flash. Thus, by using show version, then rebooting the
switch from the opposite flash image and using show version again, you can
determine the version(s) of switch software in both flash sources. For exam-

Download Interruptions. In most cases, if a power failure or other cause
interrupts a flash image download, the switch reboots with the image previ-
ously stored in primary flash. In the unlikely event that the primary image is

Using Primary and Secondary Flash Image Options
flash and you can either copy the secondary image into primary or download
another image to primary from an external source. Refer to Appendix A, “File
Transfers”.
Local Switch Software Replacement and Removal
This section describes commands for erasing a software version and copying
an existing software version between primary and secondary flash.
Note It is not necessary to erase the content of a flash location before downloading
another software file. The process automatically overwrites the previous file
with the new file. If you want to remove an unwanted software version from
flash, ProCurve recommends that you do so by overwriting it with the same
software version that you are using to operate the switch, or with another
acceptable software version. To copy a software file between the primary and
secondary flash locations, refer to “Copying a Switch Software Image from
One Flash Location to Another”, below.
The local commands described here are for flash image management within
the switch. To download a software image file from an external source, refer
to Appendix A, “File Transfers”.
Copying a Switch Software Image from One Flash Location to
Another. When you copy the flash image from primary to secondary or the
reverse, the switch overwrites the file in the destination location with a copy
of the file from the source location. This means you do not have to erase the
current image at the destination location before copying in a new image.
Caution Verify that there is an acceptable software version in the source flash location
from which you are going to copy. Use the show flash command or, if necessary,
the procedure under “Determining Which Flash Image Versions Are Installed”
on page 6-14 to verify an acceptable software version. Attempting to copy from
a source image location that has a corrupted flash image overwrites the image
in the destination flash location. In this case, the switch will not have a valid
flash image in either flash location, but will continue running on a temporary
flash image in RAM. Do not reboot the switch. Instead, immediately download
another valid flash image to primary or secondary flash. Otherwise, if the
switch is rebooted without a software image in either primary or secondary
flash, the temporary flash image in RAM will be cleared and the switch will go
down. To recover, refer to “Restoring a Flash Image” on page C-68 (in the
“Troubleshooting” Appendix).

For example, to copy the image in secondary flash to primary flash:
1. Verify that there is a valid flash image in the secondary flash location. The

Erasing the Contents of Primary or Secondary Flash. This command
deletes the software image file from the specified flash location.
Caution: Before using this command in one flash image location (primary or second-
ary), ensure that you have a valid software file in the other flash image location
No Undo! (secondary or primary). If the switch has only one flash image loaded (in either
primary or secondary flash) and you erase that image, then the switch does
not have a software image stored in flash. In this case, if you do not reboot or
power cycle the switch, you can recover by using xmodem or tftp to download
another software image.
Syntax: erase flash < primary | secondary >
For example, to erase the software image in primary flash, do the following:
1. First verify that a usable flash image exists in secondary flash. The most
reliable way to ensure this is to reboot the switch from the flash image

Operating Notes about Booting
Default Boot Source. The switch reboots from primary flash by default
unless you specify the secondary flash by entering either the boot system flash
[primary | secondary] or boot set-default flash [primary | secondary] command.
Both the boot command and the reload command will reboot based on how
these options have been selected.
Boot Attempts from an Empty Flash Location. In this case, the switch
aborts the attempt and displays
Image does not exist
Operation aborted.
Interaction of Primary and Secondary Flash Images with the Current
Configuration. The switch has one startup-config file (page 6-3), which it
always uses for reboots, regardless of whether the reboot is from primary or
secondary flash. Also, for rebooting purposes, it is not necessary for the
software image and the startup-config file to support identical software fea-
tures. For example, suppose you have just downloaded a software upgrade
that includes new features that are not supported in the software you used to
create the current startup-config file. In this case, the software simply assigns
6-18
Switch Memory and Configuration
Using Primary and Secondary Flash Image Options
factory-default values to the parameters controlling the new features. Simi-
larly, If you create a startup-config file while using a version “Y” of the switch
software, and then reboot the switch with an earlier software version “X” that
does not include all of the features found in “Y”, the software simply ignores
the parameters for any features that it does not support.
Scheduled Reload. If no parameters are entered after the reload command,
an immediate reboot is executed. The reload at and reload after command
information is not saved across reboots. If the switch is rebooted before a
scheduled reload command is executed, the command is effectively cancelled.
When entering a reload at or reload after command, a prompt will appear to
confirm the command before it can be processed by the switch. For the reload
at command, if mm/dd/yy are left blank, the current day is assumed.
The scheduled reload feature removes the requirement to physically reboot
the switch at inconvenient times (for example, at 1:00 in the morning). Instead,
a reload at 1:00 mm/dd command can be executed (where mm/dd is the date
the switch is scheduled to reboot).
Boot and Reload Command Comparison
The switch offers reboot options through the boot and reload commands, plus
the options inherent in a dual-flash image system. Generally, using boot
provides more comprehensive self-testing; using reload gives you a faster
reboot time.

Switch Memory and Configuration
Using Primary and Secondary Flash Image Options
Setting the Default Flash
You can specify the default flash to boot from on the next boot by entering the
boot set-default flash command.
Syntax: boot set-default flash [primary |secondary]
Upon booting, set the default flash for the next boot to primary
or secondary.
Booting from the Default Flash (Primary or Secondary)
The boot command boots the switch from the flash image that you are
currently booted on, or the flash image that was set either by the boot set-
default command or by the last executed boot system flash <primary | secondary>
command. This command also executes the complete set of subsystem self-
tests. You have the option of specifying a configuration file.
Syntax: boot [system [flash <primary | secondary>] [config FILENAME]
Reboots the switch from the flash that you are currently booted
on (primary or secondary). You can select which image to
boot from during the boot process itself.
Note: This is changed from always booting from primary
flash. You are prompted with a message which will indicate
the flash being booted from.
system: Boots the switch. You can specify the flash image to
boot from.
config: You can optionally select a configuration file from
which to boot.
Booting from a Specified Flash
This version of the boot command gives you the option of specifying whether
to reboot from primary or secondary flash, and is the required command for
rebooting from secondary flash. This option also executes the complete set
of subsystem self-tests.
Syntax: boot system flash < primary | secondary >
For example, to reboot the switch from secondary flash when there are no
pending configuration changes in the running-config file:
6-20
Switch Memory and Configuration
Using Primary and Secondary Flash Image Options
ProCurve(config)# boot system flash secondary
System will be rebooted from secondary image. Do you want to continue [y/n]?
Figure 6-13. Example of Boot Command with Secondary Flash Option
In the above example, typing either a y or n at the second prompt initiates the
reboot operation.
Using the Fastboot feature. The fastboot command allows a boot
sequence that skips the internal power-on self-tests, resulting in a faster boot
time.
Syntax: [no] fastboot
Enables the fastboot option
The no option disables the feature.
Syntax: show fastboot
Shows the status of the fastboot feature, either enabled or
disabled.
The fastboot command is shown below.
ProCurve(config)# fastboot
Using Reload
The Reload command reboots the switch from the flash image that you are
currently booted on (primary or secondary) or the flash image that was set
either by the boot set-default command or by the last executed boot system flash
<primary | secondary> command. Because reload bypasses some subsystem
self-tests, the switch reboots faster than if you use either of the boot command
options.
Syntax: reload
For example, if you change the number of VLANs the switch supports, you
must reboot the switch in order to implement the change. The reload command
prompts you to save or discard the configuration changes.
6-21
Switch Memory and Configuration
Using Primary and Secondary Flash Image Options
Scheduled Reload. Additional parameters have been added to the reload
command to allow for a scheduled reboot of the switch via the CLI.
Syntax: [no] reload [after <[dd:]hh:]mm> | at <hh:mm[:ss]> [<mm/dd[/[yy]yy]>]]
Enables a scheduled warm reboot of the switch. The switch boots
up with the same startup config file and using the same flash
image as before the reload.
Parameters include:
• after: Schedules a warm reboot of the switch after a given
amount of time has passed.
• at: Schedules a warm reboot of the switch at a given time.
The no form of the command removes a pending reboot request.
For more details and examples, see below.
The scheduled reload feature removes the requirement to physically reboot
the switch at inconvenient times (for example, at 1:00 in the morning). Instead,
a reload at 1:00 mm/dd command can be executed (where mm/dd is the date
the switch is scheduled to reboot).
Note Configuration changes are not saved with reload at or reload after commands.
No prompt to save configuration file changes is displayed. See Table 6-2 on
page 6-19.
Examples of scheduled reload commands:
■ To schedule a reload in 15 minutes:
ProCurve# reload after 15
■ To schedule a reload in 3 hours:
ProCurve# reload after 03:00
■ To schedule a reload for the same time the following day:
ProCurve# reload after 01:00:00
■ To schedule a reload for the same day at 12:05:
ProCurve# reload at 12:05
■ To schedule a reload on some future date:

While you can still use remote storage for startup-config files, you can now
maintain multiple startup-config files on the switch and choose which version
to use for a reboot policy or an individual reboot.
This choice of which configuration file to use for the startup-config at reboot
provides the following new options:
■ The switch can reboot with different configuration options without having
to exchange one configuration file for another from a remote storage
location.
6-23
Switch Memory and Configuration
Multiple Configuration Files
■ Transitions from one software release to another can be performed while
maintaining a separate configuration for the different software release
versions.
■ By setting a reboot policy using a known good configuration and then
overriding the policy on a per-instance basis, you can test a new configu-
ration with the provision that if an unattended reboot occurs, the switch
will come up with the known, good configuration instead of repeating a
reboot with a misconfiguration.
General Operation
Multiple Configuration Storage in the Switch. The switch uses three
memory “slots”, with identity (id) numbers of 1, 2, and 3.
Memory Slots
for Different
Startup-Config
Files
A startup-config file stored in a memory slot has a unique, changeable file
name. The switches covered in this guide can use the startup-config in any of
the memory slots (if the software version supports the configured features).
Boot Options. With multiple startup-config files in the switch you can spec-
ify a policy for the switch to use upon reboot. The options include:
■ Use the designated startup-config file with either or both reboot paths
(primary or secondary flash)
■ Override the current reboot policy for one reboot instance by specifying
a boot path (primary or secondary flash) and the startup-config file to use.
Changing the Startup-Config File. When the switch reboots, the startup-
config file supplies the configuration for the running-config file the switch uses
to operate. Making changes to the running-config file and then executing a
write-mem command (or, in the Menu interface, the Save command) are
written back to the startup-config file used at the last reboot. For example,
suppose that a system administrator performs the following on a switch that
has two startup-config files (workingConfig and backupConfig):
6-24
Switch Memory and Configuration
Multiple Configuration Files
1. Reboot the switch through the Primary boot path using the startup-config
file named backupConfig.
2. Use the CLI to make configuration changes in the running-config file, and
then execute write mem.
The result is that the startup-config file used to reboot the switch is modified
by the actions in step 2.

Creating an Alternate Startup-Config File. There are two methods for
creating a new configuration file:
■ Copy an existing startup-config file to a new filename, then reboot the
switch, make the desired changes to the running-config file, then execute
write memory. (Refer to figure 6-6-15, above.)
■ Erase the active startup-config file. This generates a new, default startup-
config file that always results when the switch automatically reboots after
deletion of the currently active startup-config file. (Refer to “Erasing a
Startup-Config File” on page 6-32.)
6-25
Switch Memory and Configuration
Multiple Configuration Files
Transitioning to Multiple Configuration Files
At the first reboot with a software release supporting multiple configuration,
the switch:
■ Assigns the filename oldConfig to the existing startup-config file (which is
stored in memory slot 1).
■ Saves a copy of the existing startup-config file in memory slot 2 with the
filename workingConfig.
■ Assigns the workingConfig file as the active configuration and the default
configuration for all subsequent reboots using either primary or second-
ary flash.

Viewing the Startup-Config File Status with Multiple
Configuration Enabled
Rebooting the switch automatically enables the multiple configuration fea-
ture.
Syntax: show config files
This command displays the available startup-config files on
the switch and the current use of each file.
id: Identifies the memory slot for each startup-config file
available on the switch.
act: An asterisk ( * ) in this column indicates that the
corresponding startup-config file is currently in use.
pri: An asterisk ( * ) in this column indicates that the
corresponding startup-config file is currently assigned to the
primary boot path.
sec: An asterisk ( * ) in this column indicates that the
corresponding startup-config file is currently assigned to the
secondary boot path.
name: Shows the filename for each listed startup-config file in
the switch. Refer to “Renaming an Existing Startup-Config
File” on page 6-31 for the command you can use to change
existing startup-config filenames.
In the default configuration, if the switch was shipped from
the factory with software installed in both the primary and
secondary boot paths, then one startup-config file named
config1 is used for both paths and is stored in memory slot 1.
Memory slots 2 and 3 are empty in this default configuration.
6-27
Switch Memory and Configuration
Multiple Configuration Files
Displaying the Content of A Specific Startup-Config File
With Multiple Configuration enabled, the switch can have up to three startup-
config files. Because the show config command always displays the content of
the currently active startup-config file, the command extension shown below
is needed to allow viewing the contents of any other startup-config files stored
in the switch.
Syntax: show config < filename >
This command displays the content of the specified startup-
config file in the same way that the show config command
displays the content of the default (currently active) startup-
config file.
Changing or Overriding the Reboot Configuration
Policy
Command Page
startup-default [ primary | secondary ] config < filename > Below
boot system flash < primary | secondary > config < filename > 6-30
You can boot the switch using any available startup-config file.
Changing the Reboot Configuration Policy. For a given reboot, the
switch automatically reboots from the startup-config file assigned to the flash
location (primary or secondary) being used for the current reboot. For exam-
ple, when you first download a software version that supports multiple
configuration files and boot from the flash location of this version, the switch
copies the existing startup-config file (named oldConfig) into memory slot 2,
renames this file to workingConfig, and assigns workingConfig as:
■ The active configuration file
■ The configuration file to use when booting from either primary or second-
ary flash.
In this case, the switch is configured to automatically use the workingConfig
file in memory slot 2 for all reboots.
You can use the following command to change the current policy so that the
switch automatically boots using a different startup-config file.
6-28
Switch Memory and Configuration
Multiple Configuration Files
Syntax: startup-default [ primary | secondary ] config < filename >
Specifies a boot configuration policy option:
[ primary | secondary ] config < filename >: Designates the
startup-config file to use in a reboot with the software
version stored in a specific flash location. Use this option
to change the reboot policy for either primary or
secondary flash, or both.
config < filename >: Designates the startup-config file to use
for all reboots, regardless of the flash version used. Use
this option when you want to automatically use the same
startup-config file for all reboots, regardless of the flash
source used.
For redundant management systems, this command affects
both the active management module and the standby manage-
ment module. The config file is copied immediately to the
standby management module and becomes the default on that
module when the next bootup occurs, unless redundancy is
disabled or the standby module has failed selftest.
Note: To override the current reboot configuration policy for
a single reboot instance, use the boot system flash command
with the options described under “Overriding the Default
Reboot Configuration Policy” on page 6-30.
For example, suppose:
■ Software release “A” is stored in primary flash and a later software release
is stored in secondary flash.
■ The system operator is using memory slot 1 for a reliable, minimal
configuration (named minconfig) for the software version in the primary
flash, and slot 2 for a modified startup-config file (named newconfig) that
includes untested changes for improved network operation with the
software version in secondary flash.
The operator wants to ensure that in case of a need to reboot by pressing the
Reset button, or if a power failure occurs, the switch will automatically reboot
with the minimal startup-config file in memory slot 1. Since a reboot due to
pressing the Reset button or to a power cycle always uses the software version
in primary flash, the operator needs to configure the switch to always boot
from primary flash with the startup-config file named minconfig (in memory
slot 1). Also, whenever the switch boots from secondary flash, the operator
also wants the startup-config named newconfig to be used. The following two
commands configure the desired behavior.
6-29
Switch Memory and Configuration
Multiple Configuration Files
ProCurve(config)# startup-default pri config minconfig
ProCurve(config) # startup-default sec config newconfig.
Overriding the Default Reboot Configuration Policy. This command
provides a method for manually rebooting with a specific startup-config file
other than the file specified in the default reboot configuration policy.
Syntax: boot system flash < primary | secondary > config < filename >
Specifies the name of the startup-config file to apply for the
immediate boot instance only. This command overrides the
current reboot policy.
Using Reload To Reboot From the Current Flash Image and Startup-
Config File.
Syntax: reload
This command boots the switch from the currently active flash
image and startup-config file. Because reload bypasses some
subsystem self-tests, the switch boots faster than if you use a
boot command.
Note: To identify the currently active startup-config file, use
the show config files command.

Renaming an Existing Startup-Config File
Syntax: rename config < current-filename > < newname-str >
This command changes the name of an existing startup-
config file. A file name can include up to 63, alphanumeric
characters. Blanks are allowed in a file name enclosed in
quotes (“ “ or ‘ ‘). (File names are not case-sensitive.)
Creating a New Startup-Config File
The switch allows up to three startup-config files. You can create a new
startup-config file if there is an empty memory slot or if you want to replace
one startup-config file with another.
Syntax: copy config < source-filename > config < target-filename >
This command makes a local copy of an existing startup-
config file by copying the contents of an existing startup-
config file in one memory slot to a new startup-config file in
another, empty memory slot. This enables you to use a sepa-
rate configuration file to experiment with configuration
changes, while preserving the source file unchanged. It also
simplifies a transition from one software version to another
by enabling you to preserve the startup-config file for the
earlier software version while creating a separate startup-
config file for the later software version. With two such
versions in place, you can easily reboot the switch with the
correct startup-config file for either software version.
• If the destination startup-config file already exists, it is
overwritten by the content of the source startup-config file.
• If the destination startup-config file does not already exist,
it will be created in the first empty configuration memory
slot on the switch.
• If the destination startup-config file does not already exist,
but there are no empty configuration memory slots on the
switch, then a new startup-config file is not created and
instead, the CLI displays the following error message:
Unable to copy configuration to “< target-filename >”.
For example, suppose both primary and secondary flash memory contain
software release “A” and use a startup-config file named config1:
6-31
Switch Memory and Configuration
Multiple Configuration Files
Figure 6-17. Example of Using One Startup-Config File for Both Primary and
Secondary Flash
If you wanted to experiment with configuration changes to the software
version in secondary flash, you could create and assign a separate startup-
config file for this purpose.
The first two commands copy the config1
startup-config file to config2, and then
make config2 the default startup-config
file for booting from secondary flash.
Figure 6-18. Example of Creating and Assigning a New Startup-Config File
Note You can also generate a new startup-config file by booting the switch from a
flash memory location from which you have erased the currently assigned
startup-config file. Refer to “Erasing a Startup-Config File” in the next section.
Erasing a Startup-Config File
You can erase any of the startup-config files in the switch’s memory slots. In
some cases, erasing a file causes the switch to generate a new, default-
configuration file for the affected memory slot.
6-32
Switch Memory and Configuration
Multiple Configuration Files
Syntax: erase < config < filename >> | startup-config >
config < filename >: This option erases the specified startup-
config file. If the specified file is not the currently active
startup-config file, then the file is simply deleted from the
memory slot it occupies. If the specified file is the currently
active startup-config file, then the switch creates a new,
default startup-config file with the same name as the erased
file, and boots using this file. (This new startup-config file
contains only the default configuration for the software
version used in the reboot.)
Note: Where a file is assigned to either the primary or the
secondary flash, but is not the currently active startup-
config file, erasing the file does not remove the flash
assignment from the memory slot for that file. Thus, if the
switch boots using a flash location that does not have an
assigned startup-config, then the switch creates a new,
default startup-config file and uses this file in the reboot.
(This new startup-config file contains only the default
configuration for the software version used in the reboot.)
Executing write memory after the reboot causes a switch-
generated filename of configx to appear in the show config
files display for the new file, where x corresponds to the
memory slot number.
startup-config: This option erases the currently active startup-
config file and reboots the switch from the currently active
flash memory location. The erased startup-config file is
replaced with a new startup-config file. The new file has
the same filename as the erased file, but contains only the
default configuration for the software version in the flash
location (primary or secondary) used for the reboot. For
example, suppose the last reboot was from primary flash
using a configuration file named minconfig. Executing
erase startup-config replaces the current content of minconfig
with a default configuration and reboots the switch from
primary flash.
6-33
Switch Memory and Configuration
Multiple Configuration Files
Figure 6-19 illustrates using erase config < filename > to remove a startup-config
file.
Figure 6-19. Example of Erasing a Non-Active Startup-Config File
With the same memory configuration as is shown in the bottom portion of
figure 6-19, executing erase startup-config boots the switch from primary flash,
resulting in a new file named minconfig in the same memory slot. The new file
contains the default configuration for the software version currently in pri-
mary flash.
Using the Clear + Reset Button Combination To Reset the
Switch to Its Default Configuration
The Clear + Reset button combination described in the Installation and
Getting Started Guide produces these results. That is, when you press the
Clear + Reset button combination, the switch:
• Overwrites the content of the startup-config file currently in memory
slot 1 with the default configuration for the software version in
primary flash, and renames this file to config1.
• Erases any other startup-config files currently in memory.
• Configures the new file in memory slot 1 as the default for both
primary and secondary flash locations (regardless of the software
version currently in secondary flash).
• Boots the switch from primary flash using the new startup-config file.

Automatic Configuration Update with
DHCP Option 66
ProCurve switches are initially booted up with the factory-shipped configura-
tion file. This feature provides a way to automatically download a different
configuration file from a TFTP server using DHCP Option 66. The prerequisites
for this to function correctly are:
■ One or more DHCP servers with Option 66 are enabled
■ One or more TFTP servers has the desired configuration file.
Caution This feature must use configuration files generated on the switch to function
correctly. If you use configuration files that were not generated on the switch,
and then enable this feature, the switch may reboot continuously.

Single Server serving Multiple VLANs • Each DHCP-enabled VLAN interface initiates DHCPDISCOVER
message, receives DHCPOFFER from the server, and send
DHCPREQUEST to obtain the offered parameters.
• If multiple interfaces send DHCPREQUESTs, it’s possible that more
than one DHCPACK is returned with a valid Option 66.
• Evaluating and updating the configuration file occurs only on the
primary VLAN.
• Option 66 is ignored by any interfaces not belonging to the primary
VLAN.
Multiple Servers serving a Single VLAN • Each DHCP-enabled VLAN interface initiates one DHCPDISCOVER
and receives one or more DHCPOFFER messages.
• Each interface accepts the best offer.
• Option 66 is processed only for the interface belonging to the primary
VLAN.

Automatic Configuration Update with DHCP Option 66
Multiple Servers serving Multiple VLANs • Each DHSP-enabled VLAN interface initiates DHCPDISCOVER and
receives one or more DHCPOFFER messages.
Scenario Behavior
• Each interface accepts the best offer.
• Option 66 is processed only for the interface belonging to the primary
VLAN.
Multi-homed Server serving Multiple VLANs • The switch perceives the multi-homed server as multiple separate
servers.
• Each DHCP-enabled VLAN interface initiates DHCPDISCOVER and
receives one DHCPOFFER message.
• Each interface accepts the offer.
• Option 66 is processed only for the interface belonging to the primary
VLAN.
Operating Notes
Replacing the Existing Configuration File: After the DHCP client down-
loads the configuration file, the switch compares the contents of that file with
the existing configuration file. If the content is different, the new configuration
file replaces the existing file and the switch reboots.
Option 67 and the Configuration File Name: Option 67 includes the name
of the configuration file. If the DHCPACK contains this option, it overrides the
default name for the configuration file (switch.cfg)
Global DHCP Parameters: Global parameters are processed only if received
on the primary VLAN.
Best Offer: The “Best Offer” is the best DHCP or BootP offer sent by the
DHCP server in response to the DHCPREQUEST sent by the switch. The
criteria for selecting the “Best Offer” are:
• DHCP is preferred over BootP
• If two BootP offers are received, the first one is selected
• For two DHCP offers:
– The offer from an authoritative server is selected
– If there is no authoritative server, the offer with the longest lease
is selected
Log Messages
The file transfer is implemented by the existing TFTP module. The system logs
the following message if an incorrect IP address is received for Option 66:
“Invalid IP address <ip-address> received for DHCP Option 66”

Interface Access and System Information
Overview
Overview
This chapter describes how to:
■ View and modify the configuration for switch interface access
■ Use the CLI kill command to terminate a remote session
■ View and modify switch system information
For help on how to actually use the interfaces built into the switch, refer to:
■ Chapter 3, “Using the Menu Interface”
■ Chapter 4, “Using the Command Line Interface (CLI)”
■ Chapter 5, “Using the ProCurve Web Browser Interface”
Why Configure Interface Access and System Information? The inter-
face access features in the switch operate properly by default. However, you
can modify or disable access features to suit your particular needs. Similarly,
you can choose to leave the system information parameters at their default
settings. However, modifying these parameters can help you to more easily
distinguish one device from another in your network.

that has an IP address.
Syntax: telnet <ipv4-addr | ipv6-addr | hostname | switch-num>
Initiates an outbound telnet session to another network
device. The destination can be specified as:
• IPv4 address
• IPv6 address
• Hostname
• Stack number of a member switch (1-16) if the
switch is a commander in a stack and stacking is
enabled
For example, if the host “Labswitch” is in the domain abc.com, you can enter
the following command and the destination is resolved to
“Labswitch.abc.com”.
ProCurve(config)# telnet Labswitch
You can also enter the full domain name in the command:
ProCurve(config)# telnet Labswitch.abc.com
You can use the show telnet command to display the resolved IP address.

[events <none | all | non-info | critical | debug]
[local-terminal <vt 100 | none | ansi>]
Note If you change the Baud Rate or Flow Control settings for the switch, you
should make the corresponding changes in your console access device. Other-
wise, you may lose connectivity between the switch and your terminal
emulator due to differences between the terminal and switch settings for these
two parameters.
All console parameter changes except events and inactivity-timer require that
you save the configuration with write memory and then execute boot before the
new console configuration will take effect.
For example, to use one command to configure the switch with the following:
■ VT100 operation
■ 19,200 baud
■ No flow control
■ Critical log events
you would use the following command sequence:
ProCurve(config)# console terminal vt100 baud-rate 19200 flow-control none
events critical
Command will take effect after saving configuration and reboot
ProCurve(config)# write memory
ProCurve(config)# reload
The switch implements the Event Log change immediately. The switch implements
the other console changes after executing write memory and reload.

Remote Management Sessions
The switch supports up to five management sessions. You can use show ip ssh
to list the current management sessions, and kill to terminate a currently
running remote session. (Kill does not terminate a Console session on the
serial port, either through a direct connection or via a modem. It does not
affect the console on the standby module.)
Syntax: kill [< session-number >]
For example, if you are using the switch’s serial port for a console session and
want to terminate a currently active Telnet session, you would do the
following:

Configuring system information is optional, but recommended.
System Name: Using a unique name helps you to identify individual devices
where you are using an SNMP network management tool such as ProCurve
Manager.
System Contact and Location: This information is helpful for identifying
the person administratively responsible for the switch and for identifying the
locations of individual switches.
MAC Age Time: The number of seconds a MAC address the switch has
learned remains in the switch’s address table before being aged out (deleted).
Aging out occurs when there has been no traffic from the device belonging to
that MAC address for the configured interval.
Time Sync Method: Selects the method (TimeP or SNTP) the switch will use
for time synchronization. For more on this topic, refer to Chapter 9, “Time
Protocols”.

Reconfigure the MAC Age Time for Learned MAC Addresses. This
command corresponds to the MAC Age Interval in the menu interface, and is
expressed in seconds.
Syntax: mac-age-time < 60 - 999960> (seconds)
Allows you to set the MAC address table’s age-out interval. An
address is aged out if the switch does not receive traffic from that
MAC address for the age-out interval, measured in seconds.
Default: 300 seconds.
For example, to configure the age time to seven minutes:
ProCurve(config)# mac-age-time 420
Configure the Time Zone and Daylight Time Rule. These commands:
■ Set the time zone you want to use
■ Define the daylight time rule for keeping the correct time when daylight-
saving-time shifts occur.
Syntax: time timezone < -720 - 840 >
time daylight-time-rule < none | alaska | continental-us-and-canada |
middle-europe-and-portugal | southern-hemisphere | western-europe |
user-defined>
East of the 0 meridian, the sign is “+”. West of the 0 meridian, the sign is “-”.
For example, the time zone setting for Berlin, Germany is +60 (zone +1, or 60
minutes), and the time zone setting for Vancouver, Canada is -480 (zone -8, or
-480 minutes). To configure the time zone and daylight time rule for Vancouver,
Canada:
ProCurve(config)# time timezone -480
daylight-time-rule continental-us-and-canada
Configure the Time and Date. The switch uses the time command to
configure both the time of day and the date. Also, executing time without
parameters lists the switch’s time of day and date. Note that the CLI uses a 24-
hour clock scheme; that is, hour (hh) values from 1 p.m. to midnight are input
as 13 - 24, respectively.
Syntax: time [ hh:mm [ :ss ]] [ mm/dd/ [ yy ] yy ]
For example, to set the switch to 9:45 a.m. on November 17, 2002:
ProCurve(config)# time 9:45 11/17/02

Configuring IP Addressing
Overview
Overview
You can configure IP addressing through all of the switch’s interfaces. You can
also:
■ Easily edit a switch configuration file to allow downloading the file to
multiple switches without overwriting each switch’s unique gateway and
VLAN 1 IP addressing.
■ Assign up to 8 IP addresses to a VLAN (multinetting).
Why Configure IP Addressing? In its factory default configuration, the
switch operates as a multiport learning bridge with network connectivity
provided by the ports on the switch. However, to enable specific management
access and control through your network, you will need IP addressing. Table
8-1 on page 8-11 shows the switch features that depend on IP addressing to
operate.

IP Address and Subnet Mask. Configuring the switch with an IP address
expands your ability to manage the switch and use its features. By default, the
switch is configured to automatically receive IP addressing on the default
VLAN from a DHCP/Bootp server that has been configured correctly with
information to support the switch. (Refer to “DHCP/Bootp Operation” on page
8-12 for information on setting up automatic configuration from a server.)
However, if you are not using a DHCP/Bootp server to configure IP addressing,
8-2
Configuring IP Addressing
IP Configuration
use the menu interface or the CLI to manually configure the initial IP values.
After you have network access to a device, you can use the web browser
interface to modify the initial IP configuration if needed.
For information on how IP addressing affects switch operation, refer to “How
IP Addressing Affects Switch Operation” on page 8-11.
Multinetting: Assigning Multiple IP Addresses to a VLAN. For a given
VLAN you can assign up to 8 IP addresses. This allows you to combine two or
more subnets on the same VLAN, which enables devices in the combined
subnets to communicate normally through the network without needing to
reconfigure the IP addressing in any of the combined subnets.
Default Gateway Operation. The default gateway is required when a
router is needed for tasks such as reaching off-subnet destinations or forward-
ing traffic across multiple VLANs. The gateway value is the IP address of the
next-hop gateway node for the switch, which is used if the requested destina-
tion address is not on a local subnet/VLAN. If the switch does not have a
manually-configured default gateway and DHCP/Bootp is configured on the
primary VLAN, then the default gateway value provided by the DHCP or Bootp
server will be used. If the switch has a manually configured default gateway,
then the switch uses his gateway, even if a different gateway is received via
DHCP or Bootp on the primary VLAN. This is also true for manually configured
TimeP, SNTP, and Time-To-Live(TTL). (In the default configuration, VLAN 1
is the Primary VLAN.) Refer to the information on Primary VLANs in the
Advanced Traffic Management Guide for your switch.
Packet Time-To-Live (TTL) . This parameter specifies the maximum num-
ber of routers (hops) through which a packet can pass before being discarded.
Each router decreases a packet’s TTL by 1 before forwarding the packet. If
decreasing the TTL causes the TTL to be 0, the router drops the packet instead
of forwarding it. In most cases, the default setting (64) is adequate.
Just Want a Quick Start with IP Addressing?
If you just want to give the switch an IP address so that it can communicate
on your network, or if you are not using VLANs, ProCurve recommends that
you use the Switch Setup screen to quickly configure IP addressing. To do so,
do one of the following:
■ Enter setup at the CLI Manager level prompt.
ProCurve# setup
■ Select 8. Run Setup in the Main Menu of the menu interface.
8-3
Configuring IP Addressing
IP Configuration
Notes
For more on using the Switch Setup screen, refer to the Installation and
Getting Started Guide you received with the switch.
IP Addressing with Multiple VLANs
In the factory-default configuration, the switch has one, permanent default
VLAN (named DEFAULT_VLAN) that includes all ports on the switch. Thus,
when only the default VLAN exists in the switch, if you assign an IP address
and subnet mask to the switch, you are actually assigning the IP addressing
to the DEFAULT_VLAN.
■ If multiple VLANs are configured, then each VLAN can have its own IP
address. This is because each VLAN operates as a separate broadcast
domain and requires a unique IP address and subnet mask. A default
gateway (IP) address for the switch is optional, but recommended.
■ In the factory-default configuration, the default VLAN (named
DEFAULT_VLAN) is the switch’s primary VLAN. The switch uses the
primary VLAN for learning the default gateway address. The switch can
also learn other settings from a DHCP or Bootp server, such as (packet)
Time-To-Live (TTL), and Timep or SNMP settings. (Other VLANs can also
use DHCP or BootP to acquire IP addressing. However, the switch’s
gateway, TTL, and TimeP or SNTP values, which are applied globally, and
not per-VLAN, will be acquired through the primary VLAN only, unless
manually set by using the CLI, Menu, or web browser interface.(If these
parameters are manually set, they will not be overwritten by alternate
values received from a DHCP or Bootp server.) For more on VLANs, refer
to the chapter titled “Static Virtual LANs” in the Advanced Traffic Man-
agement Guide for your switch.
■ The IP addressing used in the switch should be compatible with your
network. That is, the IP address must be unique and the subnet mask must
be appropriate for your IP network.
■ If you change the IP address through either Telnet access or the web
browser interface, the connection to the switch will be lost. You can
reconnect by either restarting Telnet with the new IP address or entering
the new address as the URL in your web browser.

Syntax: show ip
This command displays the IP addressing for each VLAN
configured in the switch. If only the DEFAULT_VLAN exists,
then its IP configuration applies to all ports in the switch.
Where multiple VLANs are configured, the IP addressing is
listed per VLAN. The display includes switch-wide packet
time-to-live, and (if configured) the switch’s default gateway
and Timep configuration.

(You can also use the show management command to display the IP addressing
and time server IP addressing configured on the switch. Refer to figure

For example, in the factory-default configuration (no IP addressing assigned),
the switch’s IP addressing appears as:

Configure an IP Address and Subnet Mask. The following command
includes both the IP address and the subnet mask. You must either include the
ID of the VLAN for which you are configuring IP addressing or go to the
context configuration level for that VLAN. (If you are not using VLANs on the
switch—that is, if the only VLAN is the default VLAN—then the VLAN ID is
always “1”.)

Configuring IP Addressing
IP Configuration
Note The default IP address setting for the DEFAULT_VLAN is DHCP/Bootp. On
additional VLANs you create, the default IP address setting is Disabled.
Syntax: [ no ] vlan < vlan-id > ip address <ip-address/mask-length>
or
[ no ] vlan < vlan-id > ip address < ip-address > < mask-bits >
or
vlan < vlan-id > ip address dhcp-bootp
This example configures IP addressing on the default VLAN with the subnet
mask specified in mask bits.
ProCurve(config)# vlan 1 ip address 10.28.227.103 255.255.255.0
This example configures the same IP addressing as the preceding example,
but specifies the subnet mask by mask length.
ProCurve(config)# vlan 1 ip address 10.28.227.103/24
This example deletes an IP address configured in VLAN 1.
ProCurve (config) no vlan 1 ip address 10.28.227.103/24
Configure Multiple IP Addresses on a VLAN (Multinetting). The fol-
lowing is supported:
■ Up to 2048 IP addresses for the switch
■ Up to 32 IP addresses for the same VLAN
■ Up to 256 IP VLANs, that is, VLANs on which you can configure IP
addresses
■ Each IP address on a VLAN must be for a separate subnet, whether on the
same VLAN or different VLANs.
Syntax: [ no ] vlan < vlan-id > ip address < ip-address/mask-length >
[ no ] vlan < vlan-id > ip address < ip-address > < mask-bits >
For example, if you wanted to multinet VLAN_20 (VID = 20) with the IP
addresses shown below, you would perform steps similar to the following.
(For this example, assume that the first IP address is already configured.)
IP Address VID IP Address Subnet Mask
1st address 20 10.25.33.101 255.255.240.0
2nd address 20 10.26.33.101 255.255.240.0

Removing or Replacing IP Addresses in a Multinetted VLAN. To
remove an IP address from a multinetted VLAN, use the no form of the IP
address command shown on page 8-8. Generally, to replace one IP address
with another, you should first remove the address you want to replace, and
then enter the new address.
Configure the Optional Default Gateway. Using the Global configura-
tion level, you can manually assign one default gateway to the switch. (The
switch does not allow IP addressing received from a DHCP or Bootp server
to replace a manually configured default gateway.)
Syntax: ip default-gateway < ip-address >
For example:
ProCurve(config)# ip default-gateway 10.28.227.115
Configure Time-To-Live (TTL). The maximum number of routers (hops)
through which a packet can pass before being discarded. (The default is 64.)
Each router decreases a packet’s TTL by 1 before forwarding the packet. If a
router decreases the TTL to 0, the router drops the packet instead of forward-
ing it.
Syntax: ip ttl <number-of-hops>
ProCurve(config)# ip ttl 60
In the CLI, you can execute this command only from the global configuration
level. The TTL default is 64, and the range is 2 - 255.
Web: Configuring IP Addressing
You can use the web browser interface to access IP addressing only if the
switch already has an IP address that is reachable through your network.

How IP Addressing Affects Switch Operation
Without an IP address and subnet mask compatible with your network, the
switch can be managed only through a direct terminal device connection to
the Console RS-232 port. You can use direct-connect console access to take
advantage of features that do not depend on IP addressing. However, to realize
the full capabilities ProCurve proactive networking offers through the switch,
configure the switch with an IP address and subnet mask compatible with
your network. The following table lists the general features available with and
without a network-compatible IP address configured.
Table 8-1. Features Available With and Without IP Addressing on the Switch
Features Available Without an IP Address Additional Features Available with an IP Address and
Subnet Mask
• Direct-connect access to the CLI and the menu interface.
• DHCP or Bootp support for automatic IP address
configuration, and DHCP support for automatic Timep

Note
Note
DHCP/Bootp Operation
Overview. DHCP/Bootp is used to provide configuration data from a DHCP
or Bootp server to the switch. This data can be the IP address, subnet mask,
default gateway, Timep Server address, and TFTP server address. If a TFTP
server address is provided, this allows the switch to TFTP a previously saved
configuration file from the TFTP server to the switch. With either DHCP or
Bootp, the servers must be configured prior to the switch being connected to
the network.
The switches covered in this guide are compatible with both DHCP and Bootp
servers.
The DHCP/Bootp Process. Whenever the IP Config parameter in the switch
or in an individual VLAN in the switch is configured to DHCP/Bootp (the
default), or when the switch is rebooted with this configuration:
1. DHCP/Bootp requests are automatically broadcast on the local network.
(The switch sends one type of request to which either a DHCP or Bootp
server can respond.)
2. When a DHCP or Bootp server receives the request, it replies with a
previously configured IP address and subnet mask for the switch. The
switch also receives an IP Gateway address if the server has been config-
ured to provide one. In the case of Bootp, the server must first be
configured with an entry that has the switch’s MAC address. (To determine
the switch’s MAC address, refer to Appendix D, “MAC Address Manage-
ment”.) The switch properly handles replies from either type of server. If
multiple replies are returned, the switch tries to use the first reply.)
If you manually configure default gateway, TTL, TimeP, and/or SNTP param-
eters on the switch, it ignores any values received for the same parameters via
DHCP or Bootp.
If the switch is initially configured for DHCP/Bootp operation (the default),
or if it reboots with this configuration, it begins sending request packets on
the network. If the switch does not receive a reply to its DHCP/Bootp requests,
it continues to periodically send request packets, but with decreasing fre-
quency. Thus, if a DHCP or Bootp server is not available or accessible to the
switch when DHCP/Bootp is first configured, the switch may not immediately
receive the desired configuration. After verifying that the server has become
accessible to the switch, reboot the switch to re-start the process immediately.
8-12
Configuring IP Addressing
IP Configuration
DHCP Operation. A significant difference between a DHCP configuration
and a Bootp configuration is that an IP address assignment from a DHCP
server is automatic. Depending on how the DHCP server is configured, the
switch may receive an IP address that is temporarily leased. Periodically the
switch may be required to renew its lease of the IP configuration. Thus, the IP
addressing provided by the server may be different each time the switch
reboots or renews its configuration from the server. However, you can fix the
address assignment for the switch by doing either of the following:
■ Configure the server to issue an “infinite” lease.
■ Using the switch’s MAC address as an identifier, configure the server with
a “Reservation” so that it will always assign the same IP address to the
switch. (For MAC address information, refer to Appendix D, “MAC
Address Management”.)
For more information on either of these procedures, refer to the documenta-
tion provided with the DHCP server.
Bootp Operation. When a Bootp server receives a request it searches its
Bootp database for a record entry that matches the MAC address in the Bootp
request from the switch. If a match is found, the configuration data in the
associated database record is returned to the switch. For many Unix systems,
the Bootp database is contained in the /etc/bootptab file. In contrast to DHCP
operation, Bootp configurations are always the same for a specific receiving
device. That is, the Bootp server replies to a request with a configuration
previously stored in the server and designated for the requesting device.
Bootp Database Record Entries. A minimal entry in the Bootp table file
/etc/bootptab to update an IP address and subnet mask to the switch or a VLAN
configured in the switch would be similar to this entry:
2520switch:\
ht=ether:\
ha=0030c1123456:\
ip=10.66.77.88:\
sm=255.255.248.0:\
gw=10.66.77.1:\
hn:\
vm=rfc1048
An entry in the Bootp table file /etc/bootptab to tell the switch or VLAN
where to obtain a configuration file download would be similar to this entry:
2520switch:\
ht=ether:\
ha=0030c1123456:\
ip=10.66.77.88:\
sm=255.255.248.0:\

gw=10.66.77.1:\

where:
2520switch is a user-defined symbolic name to help you find the correct section of the
bootptab file. If you have multiple switches that will be using Bootp to get their
IP configuration, you should use a unique symbolic name for each switch.
ht is the “hardware type”. For the switches covered in this guide, enter ether (for
Ethernet). This tag must precede the ha tag.
ha is the “hardware address”. Use the switch's (or VLAN's) 12-digit MAC address.
ip is the IP address to be assigned to the switch (or VLAN).
sm is the subnet mask of the subnet in which the switch (or VLAN) is installed.
gw is the IP address of the default gateway.
lg TFTP server address (source of final configuration file)
T144 is the vendor-specific “tag” identifying the configuration file to download.
vm is a required entry that specifies the Bootp report format. Use rfc1048 for the
switches covered in this guide.
Note The above Bootp table entry is a sample that will work for the switch when
the appropriate addresses and file names are used.
Network Preparations for Configuring DHCP/Bootp
In its default configuration, the switch is configured for DHCP/Bootp opera-
tion. However, the DHCP/Bootp feature will not acquire IP addressing for the
switch unless the following tasks have already been completed:
■ For Bootp operation:
• A Bootp database record has already been entered into an appropriate
Bootp server.
• The necessary network connections are in place
• The Bootp server is accessible from the switch
■ For DHCP operation:
• A DHCP scope has been configured on the appropriate DHCP server.
• The necessary network connections are in place
• A DHCP server is accessible from the switch
8-14
Configuring IP Addressing
IP Configuration
Note Designating a primary VLAN other than the default VLAN affects the switch’s
use of information received via DHCP/Bootp. For more on this topic, refer to
the chapter describing VLANs in the Advanced Traffic Management Guide
for your switch.
After you reconfigure or reboot the switch with DHCP/Bootp enabled in a
network providing DHCP/Bootp service, the switch does the following:
■ Receives an IP address and subnet mask and, if configured in the server,
a gateway IP address and the address of a Timep server.
■ If the DHCP/Bootp reply provides information for downloading a config-
uration file, the switch uses TFTP to download the file from the designated
source, then reboots itself. (This assumes that the switch or VLAN has
connectivity to the TFTP file server specified in the reply, that the config-
uration file is correctly named, and that the configuration file exists in the
TFTP directory.)

IP Preserve: Retaining VLAN-1 IP
Addressing Across Configuration File
Downloads
For the switches covered in this guide, IP Preserve enables you to copy a
configuration file to multiple switches while retaining the individual IP
address and subnet mask on VLAN 1 in each switch, and the Gateway IP
address assigned to the switch. This enables you to distribute the same
configuration file to multiple switches without overwriting their individual IP
addresses.
Operating Rules for IP Preserve
When ip preserve is entered as the last line in a configuration file stored on a
TFTP server:
■ If the switch’s current IP address for VLAN 1 was not configured by DHCP/
Bootp, IP Preserve retains the switch’s current IP address, subnet mask,
and IP gateway address when the switch downloads the file and reboots.
The switch adopts all other configuration parameters in the configuration
file into the startup-config file.
■ If the switch’s current IP addressing for VLAN 1 is from a DHCP server,
IP Preserve is suspended. In this case, whatever IP addressing the config-
uration file specifies is implemented when the switch downloads the file
and reboots. If the file includes DHCP/Bootp as the IP addressing source
for VLAN 1, the switch will configure itself accordingly and use DHCP/
Bootp. If instead, the file includes a dedicated IP address and subnet mask
for VLAN 1 and a specific gateway IP address, then the switch will
implement these settings in the startup-config file.
■ The ip preserve statement does not appear in show config listings. To verify
IP Preserve in a configuration file, open the file in a text editor and view
the last line. For an example of implementing IP Preserve in a configura-
tion file, see figure 8-6, below.
Enabling IP Preserve
To set up IP Preserve, enter the ip preserve statement at the end of a configu-
ration file. (Note that you do not execute IP Preserve by entering a command
from the CLI).

■ If the switch received its most recent VLAN 1 IP addressing from a DHCP/
Bootp server, it ignores the IP Preserve command when it downloads the
configuration file, and implements whatever IP addressing instructions
are in the configuration file.
■ If the switch did not receive its most recent VLAN 1 IP addressing from a

the configuration file.
■ The content of the downloaded configuration file determines the IP
addresses and subnet masks for other VLANs.

Time Protocols
Overview
Overview
This chapter describes:
■ SNTP Time Protocol Operation
■ Timep Time Protocol Operation
Using time synchronization ensures a uniform time among interoperating
devices. This helps you to manage and troubleshoot switch operation by
attaching meaningful time data to event and error messages.
The switch offers TimeP and SNTP (Simple Network Time Protocol) and a
timesync command for changing the time protocol selection (or turning off
time protocol operation).
Notes ■ Although you can create and save configurations for both time proto-
cols without conflicts, the switch allows only one active time protocol
at any time.
■ In the factory-default configuration, the time synchronization option
is set to TimeP, with the TimeP mode itself set to Disabled.
TimeP Time Synchronization
You can either manually assign the switch to use a TimeP server or use DHCP
to assign the TimeP server. In either case, the switch can get its time synchro-
nization updates from only one, designated Timep server. This option
enhances security by specifying which time server to use.
SNTP Time Synchronization
SNTP provides two operating modes:
■ Broadcast Mode: The switch acquires time updates by accepting the
time value from the first SNTP time broadcast detected. (In this case,
the SNTP server must be configured to broadcast time updates to the
network broadcast address. Refer to the documentation provided
with your SNTP server application.) Once the switch detects a partic-
ular server, it ignores time broadcasts from other SNTP servers unless
the configurable Poll Interval expires three consecutive times without
an update received from the first-detected server.
9-2
Time Protocols
Selecting a Time Synchronization Protocol or Turning Off Time Protocol Operation
Note To use Broadcast mode, the switch and the SNTP server must be in the same
subnet.
■ Unicast Mode: The switch requests a time update from the config-
ured SNTP server. (You can configure one server using the menu
interface, or up to three servers using the CLI sntp server command.)
This option provides increased security over the Broadcast mode by
specifying which time server to use instead of using the first one
detected through a broadcast.
Selecting a Time Synchronization
Protocol or Turning Off Time Protocol
Operation
General Steps for Running a Time Protocol on the Switch:
1. Select the time synchronization protocol: SNTP or TimeP (the default).
2. Enable the protocol. The choices are:
• SNTP: Broadcast or Unicast
• TimeP: DHCP or Manual
3. Configure the remaining parameters for the time protocol you selected.
The switch retains the parameter settings for both time protocols even if
you change from one protocol to the other. Thus, if you select a time
protocol, the switch uses the parameters you last configured for the
selected protocol.
Note that simply selecting a time synchronization protocol does not enable
that protocol on the switch unless you also enable the protocol itself (step 2,
above). For example, in the factory-default configuration, TimeP is the
selected time synchronization method. However, because TimeP is disabled
in the factory-default configuration, no time synchronization protocol is
running.
Disabling Time Synchronization
You can use either of the following methods to disable time synchronization
without changing the Timep or SNTP configuration:

Method
Used to select either SNTP, TIMEP, or None as the time synchronization method.
SNTP Mode
Disabled The Default. SNTP does not operate, even if specified by the Menu interface Time Sync Method
parameter or the CLI timesync command.
Unicast Directs the switch to poll a specific server for SNTP time synchronization. Requires at least one server
address.
Broadcast Directs the switch to acquire its time synchronization from data broadcast by any SNTP server to the
network broadcast address. The switch uses the first server detected and ignores any others.
However, if the Poll Interval expires three times without the switch detecting a time update from the
original server, it the switch accepts a broadcast time update from the next server it detects.
Poll Interval
(seconds)
In Unicast Mode: Specifies how often the switch polls the designated SNTP server for a time update.
In Broadcast Mode: Specifies how often the switch polls the network broadcast address for a time
update.
Value between 30-720 seconds.
Server Address Used only when the SNTP Mode is set to Unicast. Specifies the IP address of the SNTP server that
the switch accesses for time synchronization updates. You can configure up to three servers; one
using the menu or CLI, and two more using the CLI. Refer to “SNTP Unicast Time Polling with Multiple
SNTP Servers” on page 9-25.
Server Version Default: 3; range: 1 - 7. Specifies the SNTP software version to use, and is assigned on a per-server
basis. The version setting is backwards-compatible. For example, using version 3 means that the
switch accepts versions 1 through 3.
Priority Specifies the order in which the configured servers are polled for getting the time. Value is between
1 and 3.

Configuring (Enabling or Disabling) the SNTP Mode
Enabling the SNTP mode means to configure it for either broadcast or unicast
mode. Remember that to run SNTP as the switch’s time synchronization
protocol, you must also select SNTP as the time synchronization method by
using the CLI timesync command (or the Menu interface Time Sync Method
parameter).
Syntax: timesync sntp
Selects SNTP as the time protocol.
sntp < broadcast | unicast >
Enables the SNTP mode (below and page 9-12).
Syntax: sntp server priority < 1 - 3 > < ip-addr | ipv6-addr > [1-7 ]
Required only for unicast mode page 9-12). Provides SNTP
server address, priority, and (optionally) the server version.
The priority setting specifies the order in which the configured
servers are polled for getting the time. The server version range
is 1-7 and the default is 3.(page 9-12 ff.).
Note: For more information about IPv6 addresses, refer to the IPv6
Configuration Guide for your switch.
Syntax: sntp < 30 - 720 >
Enabling the SNTP mode also enables the SNTP poll interval
(default: 720 seconds; page 9-14).

Time Protocols
SNTP: Viewing, Selecting, and Configuring
Enabling SNTP in Broadcast Mode. Because the switch provides an SNTP
polling interval (default: 720 seconds), you need only these two commands
for minimal SNTP broadcast configuration:
Syntax: timesync sntp
Selects SNTP as the time synchronization method.
Syntax: sntp broadcast
Configures broadcast as the SNTP mode.
For example, suppose:
■ Time synchronization is in the factory-default configuration (TimeP
is the currently selected time synchronization method).
■ You want to:
1. View the current time synchronization.
2. Select SNTP as the time synchronization mode.
3. Enable SNTP for Broadcast mode.
4. View the SNTP configuration again to verify the configuration.
The commands and output would appear as follows:
ProCurve(config)# show sntp 1 show sntp displays the SNTP configuration and also shows that
TimeP is the currently active time synchronization mode.

Note: The Protocol Version parameter will also appear in show sntp listings if the IP address of an SNTP server (used
in Unicast mode) is configured in the switch. However, the protocol version is used only when SNTP is configured
for Unicast operation. See “Enabling SNTP in Unicast Mode” on page 12.
Figure 9-7. Example of Enabling SNTP Operation in Broadcast Mode
9-11
Time Protocols
SNTP: Viewing, Selecting, and Configuring
Enabling SNTP in Unicast Mode. Like broadcast mode, configuring SNTP
for unicast mode enables SNTP. However, for Unicast operation, you must
also specify the IPv4 or IPv6 address and priority (1 - 3) of at least one SNTP
server. The switch allows up to three unicast servers. You can use the Menu
interface or the CLI to configure one IPv4 server address or to replace an
existing IPv4 Unicast server address with another. To add an IPv6 server
address or any second or third server address, you must use the CLI. For more
on SNTP operation with multiple servers, refer to “SNTP Unicast Time Polling
with Multiple SNTP Servers” on page 9-25.
Syntax: timesync sntp
Selects SNTP as the time synchronization method.
Syntax: sntp unicast
Configures the SNTP mode for Unicast operation.
Syntax: sntp server priority < 1 - 3 > < ip-addr | ipv6-addr > [ 1 - 7 ]
Specifies the SNTP server address, server priority, and
(optionally) the server version. The priority setting (1-3)
specifies the order in which the configured servers are polled
for getting the time.The server version range is 1-7 and the
default is 3.
Syntax: no sntp server < ip-addr | ipv6-addr >
Deletes the specified SNTP server.
Note Deleting an SNTP server when only one is configured disables SNTP unicast
operation.
For example, to select SNTP and configure it with unicast mode and an SNTP
server at 10.28.227.141 with a server priority of 2, default server version (3),
and default poll interval (720 seconds):
ProCurve(config)# timesync sntp
Selects SNTP.
ProCurve(config)# sntp unicast
Activates SNTP in Unicast mode.
ProCurve(config)# sntp server priority 2 10.28.227.141
Specifies the SNTP server with a priority of “2” and accepts the
current SNTP server version (default: 3).

Changing the SNTP Poll Interval.
Syntax: sntp < 30..720 >
Specifies how long the switch waits between time polling
intervals. The default is 720 seconds and the range is 30 to
720 seconds. (This parameter is separate from the poll inter-
val parameter used for Timep operation.)
For example, to change the poll interval to 300 seconds:
ProCurve(config)# sntp poll-interval 300
Disabling Time Synchronization Without Changing the SNTP
Configuration. The recommended method for disabling time synchroniza-
tion is to use the timesync command.
Syntax: no timesync
Halts time synchronization without changing your SNTP
configuration.
For example, suppose SNTP is running as the switch’s time synchronization
protocol, with Broadcast as the SNTP mode and the factory-default polling
interval. You would halt time synchronization with this command:
ProCurve(config)# no timesync
If you then viewed the SNTP configuration, you would see the following:
ProCurve(config)# show sntp
SNTP Configuration
Time Sync Mode: Disabled
SNTP Mode : Broadcast

SNTP: Viewing, Selecting, and Configuring
Disabling the SNTP Mode. If you want to prevent SNTP from being used
even if selected by timesync (or the Menu interface’s Time Sync Method param-
eter), configure the SNTP mode as disabled.
Syntax: no sntp
Disables SNTP by changing the SNTP mode configuration to
Disabled.
For example, if the switch is running SNTP in Unicast mode with an SNTP
servers as shown in figure 9-9, no sntp changes the SNTP configuration as
shown below, and disables time synchronization on the switch.
ProCurve(config)# no sntp

Disables TimeP.
Note To change from one TimeP server to another, you must (1) use the no ip timep
command to disable TimeP mode, and then reconfigure TimeP in Manual
mode with the new server IP address.
For example, to select TimeP and configure it for manual operation using a
TimeP server address of 10.28.227.141 and the default poll interval (720
minutes, assuming the TimeP poll interval is already set to the default):
ProCurve(config)# timesync timep
Selects TimeP.
ProCurve(config)# ip timep manual 10.28.227.141
Activates TimeP in Manual mode.

Time Protocols
TimeP: Viewing, Selecting, and Configuring
Changing the TimeP Poll Interval. This command lets you specify how
long the switch waits between time polling intervals. The default is 720
minutes and the range is 1 to 9999 minutes. (This parameter is separate from
the poll interval parameter used for SNTP operation.)
Syntax: ip timep < dhcp | manual > interval < 1 - 9999 >
For example, to change the poll interval to 60 minutes:
ProCurve(config)# ip timep interval 60
Disabling Time Synchronization Without Changing the TimeP
Configuration. The recommended method for disabling time synchroniza-
tion is to use the timesync command. This halts time synchronization without
changing your TimeP configuration.
Syntax: no timesync
Disables time synchronization by changing the Time Sync
Mode configuration to Disabled.
For example, suppose TimeP is running as the switch’s time synchronization
protocol, with DHCP as the TimeP mode, and the factory-default polling
interval. You would halt time synchronization with this command:
ProCurve(config)# no timesync
If you then viewed the TimeP configuration, you would see the following:
Figure 9-18. Example of TimeP with Time Sychronization Disabled
Disabling the TimeP Mode. Disabling the TimeP mode means to configure
it as disabled. (Disabling TimeP prevents the switch from using it as the time
synchronization protocol, even if it is the selected Time Sync Method option.)
Syntax: no ip timep
Disables TimeP by changing the TimeP mode configuration
to Disabled.
9-23
Time Protocols
TimeP: Viewing, Selecting, and Configuring
For example, if the switch is running TimeP in DHCP mode, no ip timep changes
the TimeP configuration as shown below, and disables time synchronization.
Even though the Time Sync Mode is set to Timep,
time synchronization is disabled because no ip
timep has disabled the TimeP Mode parameter.

Time Protocols
SNTP Unicast Time Polling with Multiple SNTP Servers
SNTP Unicast Time Polling with Multiple
SNTP Servers
When running SNTP unicast time polling as the time synchronization method,
the switch requests a time update from the server you configured with either
the Server Address parameter in the menu interface, or the primary server in
a list of up to three SNTP servers configured using the CLI. If the switch does
not receive a response from the primary server after three consecutive polling
intervals, the switch tries the next server (if any) in the list. If the switch tries
all servers in the list without success, it sends an error message to the Event
Log and reschedules to try the address list again after the configured Poll
Interval time has expired.
Displaying All SNTP Server Addresses Configured on
the Switch
The System Information screen in the menu interface displays only one SNTP
server address, even if the switch is configured for two or three servers. The
CLI show management command displays all configured SNTP servers on the
switch.
ProCurve(config)# show management

Adding and Deleting SNTP Server Addresses
Adding Addresses. As mentioned earlier, you can configure one SNTP
server address using either the Menu interface or the CLI. To configure a
second and third address, you must use the CLI. To configure the remaining
two addresses, you would do the following:
ProCurve(config)# sntp server 2001:db8::215:60ff:fe79:8980
ProCurve(config)# sntp server 10.255.5.24
Figure 9-21. Example of Creating Additional SNTP Server Addresses with the CLI
Note If there are already three SNTP server addresses configured on the switch,
and you want to use the CLI to replace one of the existing addresses with a
new one, you must delete the unwanted address before you configure the new
one.
Deleting Addresses. To delete an address, you must use the CLI. If there are
multiple addresses and you delete one of them, the switch re-orders the
address priority.
Syntax: no sntp server < ip-addr >
For example, to delete the primary address in the above example (and
automatically convert the secondary address to primary):
ProCurve(config)# no sntp server 10.28.227.141
Menu: Operation with Multiple SNTP Server Addresses
Configured
When you use the Menu interface to configure an SNTP server IP address, the
new address writes over the current primary address, if one is configured.
SNTP Messages in the Event Log
If an SNTP time change of more than three seconds occurs, the switch’s event
log records the change. SNTP time changes of less than three seconds do not
appear in the Event Log.

Port Status and Configuration
Viewing Port Status and Configuring Port Parameters
Status of Ports
A port can be enabled or disabled:
■ Yes : Enabled, the default. This indicates the port is ready for a network
connection.
■ No: Disabled, the port will not operate, even if properly connected to a
network. Use the setting, for example, to shut the port down for diagnostic
purposes or while you are making topology changes.
The status of a port can be up or down (Read-only):
Up: The port senses a link beat.
Down: The port is not enabled, has no cables connected, or is experiencing a
network error. For troubleshooting information, see the Installation and
Getting Started Guide for your switch, or refer to Appendix C, “Troubleshoot-
ing” (in this manual).
Flow Control
With the port mode set to Auto (the default) and flow control on (enabled),
the switch negotiates flow control on the indicated port. If the port mode is
not set to Auto, or if flow control is off (disabled) on the port, then flow control
is not used. Flow control must be enabled on both ends of a link.
■ On: Enabled. The port uses 802.3x Link Layer Flow Control, generates
flow control packets, and processes received flow control packets.
■ Off: Disabled (default).The port does not generate flow control packets,
and drops any flow control packets it receives.
Broadcast Limit
The broadcast limit specifies the percentage of the theoretical maximum
network bandwidth that can be used for broadcast and multicast traffic. Any
broadcast or multicast traffic exceeding that limit will be dropped. Zero (0)
means the feature is disabled.
The broadcast-limit command operates at the port context level to set the
broadcast limit for a port on a switch.
Note This feature is not appropriate for networks that require high levels of IPX or
RIP broadcast traffic.

Port Status and Configuration
Viewing Port Status and Configuring Port Parameters
Modes
The mode is the port’s speed and duplex (date transfer operation) setting.
Table 10-1 shows possible modes available, depending on the port type
(copper or fiber) and port speed.
Table 10-1. Supported Modes
Mode Speed and Duplex Settings
Auto-MDIX Senses speed and negotiates with the port at the other end of the link for port
operation (MDI-X or MDI). To see what the switch negotiates for the Auto
setting, use the CLI show interfaces brief command or the menu commands “1.
Status and Counters”, “3. Port Status”.
This features applies only to copper port switches using twisted-pair copper
Ethernet cables.
MDI Sets the port to connect with a PC using a crossover cable (Manual mode—
applies only to copper port switches using twisted-pair copper Ethernet
cables).
MDIX Sets the port to connect with a PC using a straight-through cable (Manual
mode—applies only to copper port switches using twisted-pair copper Ethernet
cables).
Auto-10 Allows the port to negotiate between half-duplex (HDx) and full-duplex (FDx)
while keeping speed at 10Mbps. Also negotiates flow control (enabled or
disabled). ProCurve recommends Auto-10 for links between 10/100 auto-
sensing ports connected with Cat 3 cabling. (Cat 5 cabling is required for 100
Mbps links.)
Auto-100 Uses 100 Mbps and negotiates with the port at the other end of the link for other
port operation features.
Auto-10-100 Allows the port to establish a link with the port at the other end at either 10 Mbps
or 100 Mbps, using the highest mutual speed and duplex mode available. Only
these speeds are allowed with this setting.
Auto-1000 Uses 1000 Mbps and negotiates with the port at the other end of the link for
other port operation features.
10HDx Uses 10 Mbps, Half-Duplex
100HDx Uses 100 Mbps, Half-Duplex
10FDX Uses 10 Mbps, Full-Duplex

Note on Using Pattern Matching with the
“Show Interfaces Custom” Command
If you have included a pattern matching command to search for a field in the
output of the show int custom command and the show int custom command
produces an error, the error message may not be visible and the output is
empty. For example, if you enter a command that produces an error (vlan is
misspelled) with the pattern matching include option:
ProCurve(config)# show int custom 1-3 name vlun |
include vlan1
the output may be empty. It is advisable to try the show int custom command
first to ensure there is output, and then enter the command again with the
pattern matching option.

Figure 10-7. Example of a Show Interface Port-Utilization Command Listing
Operating Notes:
■ For each port on the switch, the command provides a real-time display
of the rate at which data is received (Rx) and transmitted (Tx) in terms
of kilobits per second (KBits/s), number of packets per second (Pkts/
s), and utilization (Util) expressed as a percentage of the total band-
width available.
■ The show interfaces <port-list> command can be used to display the
current link status and the port rate average over a 5 minute period.
Port rates are shown in bits per second (bps) for ports up to 1 Gigabit;
for 10 Gigabit ports, port rates are shown in kilobits per second
(Kbps).

Enabling or Disabling Ports and Configuring Port Mode
You can configure one or more of the following port parameters.
Syntax: [no] interface < port-list >
[< disable | enable >]
Disables or enables the port for network traffic. Does not
use the no form of the command. (Default: enable.)
[speed-duplex < auto-10 |10-full | 10-half | 100-full | 100-half |1000-full
|auto| auto 100 | auto-1000 | auto 10-100 >]
Specifies the port’s data transfer speed and mode. Does
not use the no form of the command. (Default: auto.)
Note that in the above syntax you can substitute an “int” for “interface”; that
is: int < port-list >.
The 10/100 auto-negotiation feature allows a port to establish a link with a port
at the other end at either 10 Mbps or 100 Mbps, using the highest mutual speed
and duplex mode available. Only these speeds are allowed with this setting.
For example, to configure port 5 for auto-10-100, enter this command:
ProCurve(config)# int 5 speed-duplex auto-10-100
To configure ports 1 through 3 and port 6 for 100Mbps full-duplex, you would
enter these commands:
ProCurve(config)# int 1-3,6 speed-duplex 100-full
Similarly, to configure a single port with the above command settings, you
could either enter the same command with only the one port identified, or go
to the context level for that port and then enter the command. For example,
to enter the context level for port 6 and then configure that port for 100FDx:
ProCurve(config)# int e 6
ProCurve(eth-6)# speed-duplex 100-full
If port 8 was disabled, and you wanted to enable it and configure it for 100FDx
with flow-control active, you could do so with either of the following com-
mand sets.
10-16
Port Status and Configuration
Viewing Port Status and Configuring Port Parameters
These commands enable and configure
port 8 from the config level:
ProCurve(config)# int 8 enable
ProCurve(config)# int 8 speed-duplex 100-full
ProCurve(config)# int 8 flow-control
ProCurve(config)# int 8
ProCurve(eth-8)# enable
ProCurve(eth-8)# speed-duplex 100-full
These commands select the port 8
context level and then apply the
subsequent configuration commands to
port 8:
Figure 10-9. Examples of Two Methods for Changing a Port Configuration
Refer to “Enabling or Disabling Flow Control” on page 10-17 for more on flow
control.
Enabling or Disabling Flow Control
Note You must enable flow control on both ports in a given link. Otherwise, flow
control does not operate on the link, and appears as Off in the show interfaces
brief port listing, even if flow control is configured as enabled on the port in
the switch. (Refer to Figure 10-3 on page 10-9.) Also, the port (speed-duplex)
mode must be set to Auto (the default).
To disable flow control on some ports, while leaving it enabled on other ports,
just disable it on the individual ports you want to exclude.
Syntax: [ no ]interface < port-list > flow-control
Enables or disables flow control packets on the port. The “no”
form of the command disables flow control on the individual
ports. (Default: Disabled.)
For example, suppose that:
1. You want to enable flow control on ports 5-6.
2. Later you want to disable flow control on those ports.
Assuming that flow control is currently disabled on the switch, you would use
these commands:

Port Status and Configuration
Viewing Port Status and Configuring Port Parameters
Configuring a Broadcast Limit on the Switch
Broadcast-Limit on switches covered in this guide is configured on a per-port
basis. You must be at the port context level for this command to work, for
example:
ProCurve(config)#int B1
ProCurve(int B1)# broadcast-limit 1
Broadcast-Limit.
Syntax: broadcast-limit <0-99>
Enables or disables broadcast limiting for outbound
broadcasts on a selected port on the switch. The value selected
is the percentage of traffic allowed, for example, broadcast-limit
5 allows 5% of the maximum amount of traffic for that port. A
value of zero disables broadcast limiting for that port.
Note: You must switch to port context level before issuing the
broadcast-limit command.
Note: This feature is not appropriate for networks requiring
high levels of IPX or RIP broadcast traffic.
Syntax: show config
Displays the startup-config file. The broadcast limit setting
appears here if enabled and saved to the startup-config file.
Syntax: show running-config
Displays the running-config file. The broadcast limit setting
appears here if enabled. If the setting is not also saved to the
startup-config file, rebooting the switch returns broadcast
limit to the setting currently in the startup-config file.
For example, the following command enables broadcast limiting of 1 percent
of the traffic rate on the selected port on the switch:
ProCurve(int B1)# broadcast-limit 1
For a one Gbps port this results in a broadcast traffic rate of ten Mbps.
Configuring ProCurve Auto-MDIX
Copper ports on the switch can automatically detect the type of cable config-
uration (MDI or MDI-X) on a connected device and adjust to operate appro-
priately.
10-19
Port Status and Configuration
Viewing Port Status and Configuring Port Parameters
This means you can use a “straight-through” twisted-pair cable or a “cross-
over” twisted-pair cable for any of the connections—the port makes the
necessary adjustments to accommodate either one for correct operation. The
following port types on your switch support the IEEE 802.3ab standard, which
includes the “Auto MDI/MDI-X” feature:
■ 10/100-TX module ports
■ 100/1000-T module ports
■ 10/100/1000-T module ports
Using the above ports:
■ If you connect a copper port using a straight-through cable on a switch to
a port on another switch or hub that uses MDI-X ports, the switch port
automatically operates as an MDI port.
■ If you connect a copper port using a straight-through cable on a switch to
a port on an end node, such as a server or PC, that uses MDI ports, the
switch port automatically operates as an MDI-X port.
ProCurve Auto-MDIX was developed for auto-negotiating devices, and was
shared with the IEEE for the development of the IEEE 802.3ab standard.
ProCurve Auto-MDIX and the IEEE 802.3ab Auto MDI/MID-X feature are
completely compatible. Additionally, ProCurve Auto-MDIX supports opera-
tion in forced speed and duplex modes.
If you want more information on this subject please refer to the IEEE 802.3ab
Standard Reference.
For more information on MDI-X, refer to the appendix titled “Switch Ports and
Network Cables” in the Installation and Getting Started Guide for your
switch.
Manual Override. If you require control over the MDI/MDI-X feature you can
set the switch to either of two non-default modes:
■ Manual MDI
■ Manual MDI-X
Table 10-4 shows the cabling requirements for the MDI/MDI-X settings.

Syntax: interface < port-list > mdix-mode < automdix | mdi | mdix >
automdix is the automatic, default setting. This configures the
port for automatic detection of the cable (either straight-through
or crossover).
mdi is the manual mode setting that configures the port for
connecting to either a PC or other MDI device with a crossover
cable, or to a switch, hub, or other MDI-X device with a straight-
through cable.
mdix is the manual mode setting that configures the port for
connecting to either a switch, hub, or other MDI-X device with
a crossover cable, or to a PC or other MDI device with a straight-
through cable.
Syntax: show interfaces config
Lists the current per-port Auto/MDI/MDI-X configuration.
Syntax: show interfaces brief
Where a port is linked to another device, this command lists
the MDI mode the port is currently using. In the case of ports
configured for Auto (automdix), the MDI mode appears as
either MDI or MDIX, depending upon which option the port has
negotiated with the device on the other end of the link. In the
case of ports configured for MDI or MDIX, the mode listed in
this display matches the configured setting. If the link to
another device was up, but has gone down, this command
shows the last operating MDI mode the port was using. If a
port on a given switch has not detected a link to another device
since the last reboot, this command lists the MDI mode to
which the port is currently configured.
For example, show interfaces config displays the following data when port 1 is
configured for auto-mdix, port 2 is configured for mdi, and port 3 is configured
for mdix.

This feature enables you to assign alphanumeric port names of your choosing
to augment automatically assigned numeric port names. This means you can
configure meaningful port names to make it easier to identify the source of
information listed by some Show commands. (Note that this feature augments
port numbering, but does not replace it.)
Configuring and Operating Rules for Friendly Port
Names
■ At either the global or context configuration level you can assign a unique
name to a port. You can also assign the same name to multiple ports.
■ The friendly port names you configure appear in the output of the show
name [ port-list ], show config, and show interface < port-number > commands.
They do not appear in the output of other show commands or in Menu
interface screens. (Refer to “Displaying Friendly Port Names with Other
Port Data” on page 10-25.)
■ Friendly port names are not a substitute for port numbers in CLI com-
mands or Menu displays.
■ Trunking ports together does not affect friendly naming for the individual
ports. (If you want the same name for all ports in a trunk, you must
individually assign the name to each port.)
■ A friendly port name can have up to 64 contiguous alphanumeric charac-
ters.
■ Blank spaces within friendly port names are not allowed, and if used,
cause an invalid input error. (The switch interprets a blank space as a name
terminator.)
10-23
Port Status and Configuration
Using Friendly (Optional) Port Names
■ In a port listing, not assigned indicates that the port does not have a name
assignment other than its fixed port number.
■ To retain friendly port names across reboots, you must save the current
running-configuration to the startup-config file after entering the friendly
port names. (In the CLI, use the write memory command.)
Configuring Friendly Port Names
Syntax: interface < port-list > name < port-name-string >
Assigns a port name to port-list.
Syntax: no interface < port-list > name
Deletes the port name from port-list.
Configuring a Single Port Name. Suppose that you have connected port
A3 on the switch to Bill Smith’s workstation, and want to assign Bill’s name
and workstation IP address (10.25.101.73) as a port name for port A3:

group. In this case you might configure ports A5 through A8 with the name
“Draft-Server:Trunk”.
Figure 10-15. Example of Configuring One Friendly Port Name on Multiple Ports
Displaying Friendly Port Names with Other Port Data
You can display friendly port name data in the following combinations:
■ show name: Displays a listing of port numbers with their corresponding
friendly port names and also quickly shows you which ports do not have
friendly name assignments. (show name data comes from the running-
config file.)
■ show interface <port-number>: Displays the friendly port name, if any, along
with the traffic statistics for that port. (The friendly port name data comes
from the running-config file.)
■ show config: Includes friendly port names in the per-port data of the
resulting configuration listing. (show config data comes from the startup-
config file.)

Using Friendly (Optional) Port Names
Syntax: show config

configuration settings.
For example, if you configure port A1 with a friendly port name:
Figure 10-19. Example Listing of the Startup-Config File with a Friendly Port Name Configured (and Saved)
This command sequence
saves the friendly port name
for port A1 in the startup-
config file. The name entered
for port A2 is not saved
because it was executed after
write memory.
In this case, show config lists
only port A1. Executing write
mem after entering the name for
port A2, and then executing
show config again would result
in a listing that includes both
ports.
Listing includes friendly
port name for port A1
only.
Configuring Transceivers and Modules That Haven’t
Been Inserted
Transceivers
Previously, a port had to be valid and verified for the switch to allow it to be
configured. Transceivers are removable ports and considered invalid when
not present in the switch, so they cannot be configured unless they are already
in the switch. For switches covered in this guide, the verification for allowable
port configurations performed by the CLI is removed and configuration of
transceivers is allowed even if they are not yet inserted in the switch.

Power Over Ethernet (PoE) Operation
Overview
Overview
Power Over Ethernet (PoE) technology allows IP telephones, wireless LAN
access points, and other powered devices (PDs) to receive power and transfer
data over existing LAN cabling.
The PoE feature described in this chapter operates on the following switches:
■ ProCurve Switch 2520-8-PoE (J9137A)
■ ProCurve Switch 2520-24-PoE (J9138A)
■ ProCurve Switch 2520G-8-PoE
■ ProCurve Switch 2520G-24-PoE
The switches provision their 10/100Base-TX ports (ProCurve 2520 switches)
or 10/100/1000Base-TX ports (ProCurve 2520G switches) with power for PoE
applications compatible with the IEEE 802.3af standard. The PoE ports on
your switch support both standard networking links and PoE links. Thus, you
can connect either a non-PoE device or a powered device (PD) to a
PoE-enabled port without reconfiguring the port.
Configuration Options
In the default configuration, all 10/100Base-TX ports on the HP ProCurve 2520
switches and 10/100/1000Base-TX ports on the 2520G switches support PoE
operation. Using the commands described in this chapter, you can:
■ Configure a power threshold for SNMP and Event Log reporting of
PoE consumption on the switch.
■ Configure per-port priority for allocating power in case the switch
becomes oversubscribed and must drop power for some
lower-priority ports to support the demand on other, higher-priority
ports.
■ Disable or re-enable per-port PoE operation on some ports to help
control power usage and avoid oversubscribing PoE on the switch.
■ Monitor PoE status and performance on the switch.
See “Configuring PoE Operation” on page 11-6 for further details.

Terminology
The following PoE terms and concepts are used in this manual.
Term Use in this Manual
active PoE port A PoE-enabled port connected to a PD requesting power.
priority class Refers to the type of power prioritization where the switch uses Low (the default), High, and
Critical priority assignments to determine which groups of ports will receive power. Note
that power priority rules apply only if PoE provisioning on the switch becomes
oversubscribed.
EPS External Power Supply. An EPS device provides power to provision PoE ports on a switch.
See also “RPS” below.
Oversubscribed The state where there are more PDs requesting PoE power than can be accommodated.
MPS Maintenance Power Signature; the signal a PD sends to the switch to indicate that the PD
is connected and requires power. Refer to Figure 11-6 on page 19.
PD Powered Device. A device that receives power through a direct connection to a 10/100
Base-TX PoE RJ-45 port on the switch. Examples of PDs include Voice-over-IP (VoIP)
telephones, wireless access points, and remote video cameras.
PoE Power-Over-Ethernet; the method by which PDs receive power from a PoE module
(operates according to the IEEE 802.3af standard). Some pre-standard PoE devices are also
supported; refer to the FAQs for your switch model.
port-number
priority
Refers to the type of power prioritization where, within a priority class, the switch assigns
the highest priority to the lowest-numbered port, the second-highest priority to the second
lowest-numbered port, and so-on. Note that power priority rules apply only if PoE
provisioning on the switch becomes oversubscribed.

priority class Refers to the type of power prioritization that uses Low (the default), High, and Critical
priority assignments to determine which groups of ports will receive power. Note that power
priority rules apply only if PoE provisioning becomes oversubscribed.
PSE Power-Sourcing Equipment. A PSE provides power to IEEE 802.3af-compliant or IEEE
802.3at-compliant PDs directly connected to the ports on the module. The PoE module is an
endpoint PSE.
RPS Redundant Power Supply. An RPS device provides power to a switch if the switch’s internal
power supply fails. RPS power does not provision PoE ports on a switch whose internal
power supply has failed. See also “EPS” above.
PoE Operation
Powered Device (PD) Support
The switch must have a minimum of 17 watts of unused PoE power available
when you connect an 802.3af-compliant PD, regardless of how much power
the PD actually uses.
Note that once a PD connects to a port and begins operating, the port retains
only enough PoE power to support the PD’s operation. Unneeded power
becomes available for supporting other PD connections. Thus, while 17 watts
must be available for the switch to begin supplying power to a port with a PD
connected, 17 watts per port is not continually required if the connected PD
requires less power.
For example, with 20 watts of PoE power remaining available on the switch,
you can connect one new PD without losing power to any currently connected
PDs. If that PD draws only 3 watts, then 17 watts remain available and you can
connect at least one more PD without interrupting power to any other devices.
If the next PD you connect draws 5 watts, then only 12 watts remain unused.
With only 12 watts available, if you connect yet another PD, the lowest-priority
port will lose PoE power until the switch once again has 17 or more watts
available. (For information on power priority, refer to “Power Priority
Operation” on page 11-5.)
Disconnecting a PD from a port causes the switch to stop providing PoE power
to that port and makes the power available to other ports configured for PoE
operation. If the PoE demand becomes greater than the available power, the
switch transfers power from lower-priority ports to higher-priority ports.
(Ports not currently providing power to PDs are not affected.)
11-5
Power Over Ethernet (PoE) Operation
PoE Operation
Note Depending on power demands, lower-priority ports on a switch with high PoE
power demand may occasionally lose power due to the demands of higher-
priority ports. (Refer to “Power Priority Operation” for further details.)
Power Priority Operation
In the default configuration PoE power priority is determined by port number,
with the lowest numbered port having the highest priority.
When Is Power Allocation Prioritized?
If a PSE can provide power for all connected PD demand, it does not use its
power priority settings to allocate power. However, if the PD power demand
oversubscribes the available power, then the power allocation is prioritized
to the ports that present a PD power demand. This causes the loss of power
from one or more lower-priority ports to meet the power demand on other,
higher-priority ports. This operation occurs regardless of the order in which
PDs connect to the switch’s PoE-enabled ports.
How Is Power Allocation Prioritized?
There are two ways that PoE power is prioritized:
■ Using a priority class method, a power priority of Low (the default),
High, or Critical is assigned to each enabled PoE port.
■ Using a port-number priority method, a lower-numbered port has
priority over a higher-numbered port within the same configured
priority class, for example, port A1 has priority over port A5 if both
are configured with High priority.

Power Over Ethernet (PoE) Operation
Configuring PoE Operation
Configuring PoE Operation
In the default configuration, PoE support is enabled on the PoE ports. The
default priority for all ports is Low and the default power notification threshold
is 80 (%).
Using the CLI, you can:
■ Disable or re-enable PoE operation on individual PoE ports
■ Enable support for pre-standard devices
■ Change the PoE priority level on individual PoE ports
■ Change the threshold for generating a power level notice
Disabling or Re-Enabling PoE Port Operation
Syntax: [no] interface <port-list > power-over-ethernet
Re-enables PoE operation on <port-list > and restores the priority
setting in effect when PoE was disabled on <port-list >. The no form
of the command disables PoE operation on <port-list >. (Default:
All PoE ports are initially enabled for PoE operation at Low
priority. If you configure a higher priority, this priority is
retained until you change it.)
Note: For PoE, disabling all ports allows the 22 W of minimum
PoE power to be recovered and used elsewhere. You must disable
ALL ports for this to occur.
Enabling Support for Pre-Standard Devices
By default, all ProCurve PoE switches support 802.3af-standard PDs. In
addition, the switches covered in this guide have the ability to supply power
to pre-802.3af-standard devices, such as legacy (non-standard) IP phones.
Note When the switch is in legacy detection mode, the detection signature range is
expanded beyond the IEEE specification. This allows non-compliant devices
to be powered.

Configuring PoE Operation
Configuring the PoE Port Priority Level
Syntax: interface < port-list > power-over-ethernet [ critical | high | low ]
Reconfigures the PoE priority level on <port-list >. For a given level,
ports are prioritized by port number in ascending order. For
example, if ports 1-24 have a priority level of critical, port 1 has
priority over ports 2-24.
If there is not enough power available to provision all active PoE
ports at a given priority level, then the lowest-numbered port at that
level will be provisioned first. PoE priorities are invoked only when
all active PoE ports cannot be provisioned (supplied with PoE
power).
• Critical: Specifies the highest-priority PoE support for
<port-list >. The active PoE ports at this level are provisioned before
the PoE ports at any other level are provisioned.
• High: Specifies the second priority PoE support for
<port-list >. The active PoE ports at this level are provisioned before
the Low priority PoE ports are provisioned.
• Low: (the default): Specifies the third priority PoE support for
<port-list >. The active PoE ports at this level are provisioned only
if there is power available after provisioning any active PoE
ports at the higher priority levels.
Table 11-1 provides examples of how PoE priority settings impact operation.

Priority
Setting
Configuration Command and Resulting Operation
Critical This priority class always receives power. If there is not enough power to provision PDs on all of the ports
configured for this class, then no power goes to ports configured for High and Low priority. If there is
enough power to provision PDs on only some of the “Critical” ports, then power is allocated to the “Critical”
ports in ascending order, beginning with the lowest-numbered port in the class. For this example, the CLI
command to set ports to “Critical” is:
ProCurve(config)# interface 1-3 power critical
High This priority class receives power only if all PDs on ports with a Critical priority setting are receiving full
power. If there is not enough power to provision PDs on all ports with a High priority, then no power goes
to ports with a Low priority. If there is enough power to provision PDs on only some of the “High” ports,
then power is allocated to the “High” ports in ascending order until all available power is in use. For this
example, the CLI command to set ports to “High” is:
ProCurve(config)# interface 4-7 power high

available power is in use. For this example, the CLI command to set ports to “Low” is:
ProCurve(config)# interface 8-14 power low
- n/a - For this example, PoE is disabled on these ports. The CLI command for this setting is:
ProCurve(config)# no interface 15-23 power
Controlling PoE Allocation
The default option for PoE allocation is usage, which is what a PD attached
to the port is allocated. You can override this value by specifying the amount
of power allocated to a port by using the class or value options.
Syntax: [no] int <port-list> poe-allocate-by [usage | class | value]
Allows you to manually allocate the amount of PoE power for
a port by either its class or a defined value.
usage: The automatic allocation by a PD
class: Uses the power ramp-up signature of the PD to identify
which power class the device will be in. Classes and their
ranges are shown in table 11-1.
value: A user-defined level of PoE power allocated for that port.
Note The allowable PD requirements are lower than those specified for PSEs to
allow for power losses along the Cat-5 cable.

Table 11-1. Power Classes and Their Values
Power Class Value
0 Depends on cable type and PoE architecture. Maximum
power level output of 15.4 watts at the PSE.
This is the default class; if there isn’t enough information
about the load for a specific classification, the PSE
classifies the load as class 0 (zero).
1 Requires at least 4 watts at the PSE.
2 Requires at least 7 watts at the PSE.
3 15.4 watts
4 For PoE+
Maximum power level output of 30 watts at the PSE.
For example, to allocate by class for ports 6 - 8:
ProCurve(config)# int 6-8 PoE-allocate-by class
Manually Configuring PoE Power Levels
You can specify a power level (in watts) allocated for a port by using the value
option. This is the maximum amount of power that will be delivered.
To configure a port by value, first set the PoE allocation by entering the poe-
allocate-by value command:
ProCurve(config)# int 6 poe-allocate-by value
or in interface context:
ProCurve(eth-6)# poe-allocate-by value
Then select a value:
ProCurve(config)# int 6 poe-value 15
or in interface context:

Changing the Threshold for Generating a Power Notice
By default, PoE support is enabled on the switch’s 10/100Base-TX ports, with
the power priority set to Low and the power threshold set to 80 (%). The
following commands allow you to adjust these settings.
Syntax: power threshold < 1 - 99 >
The power threshold is a configurable percentage of the total
PoE power available on the switch. When PoE consumption
exceeds the threshold, the switch automatically generates an
SNMP trap and also sends a message to the Event Log. For
example, if the power threshold is set to 80% (the default), and
an increasing PoE power demand crosses this threshold, the
switch sends an SNMP trap and generates this Event Log
message:
PoE usage has exceeded threshold of 80 %.
If the switch is configured for debug logging, it also sends the
same message to the configured debug destination(s).
The switch automatically invokes the power threshold at the
global configuration level with a default setting of 80%. You
can configure the power threshold to a value in the range of
1% to 99%.
If an increasing PoE power load (1) exceeds the configured
power threshold (which triggers the log message and SNMP
trap), and then (2) later begins decreasing and drops below
the threshold again, the switch generates another SNMP trap,
plus a message to the Event Log and any configured Debug
destinations. To continue the above example:
PoE usage is below configured threshold
of 80 %.
(Refer to “PoE Event Log Messages” on page 11-21.)

Cycling Power on a Port
Simply disabling a PoE port does not affect power delivery through that port.
To cycle the power on a PD receiving power from a PoE port on the switch,
disable, then re-enable the power to that port.
Syntax: [no] interface [e] < port-list > power
Re-enables PoE operation on < port-list > and restores the
priority setting in effect when PoE was disabled on
< port-list >. The [no] form of the command disables PoE
operation on < port-list >. (Default: All 10/100Base-TX ports on
the switch enabled for PoE operation at Low priority.)
For example, to cycle the power on a PoE device connected to port 1 on a
switch covered in this guide:
ProCurve(config)# no interface 1 power

PoE/PoE+ Allocation Using LLDP Information
PoE/PoE+ Allocation Using LLDP
Information
LLDP with PoE
When using PoE, enabling poe-lldp-detect allows automatic power configura-
tion if the link partner supports PoE. When LLDP is enabled, the information
about the power usage of the PD is available and the switch can then comply
with or ignore this information. You can configure PoE on each port according
to the PD (IP phone, wireless device, etc.) specified in the LLDP field. The
default configuration is for PoE information to be ignored if detected through
LLDP.
Note Detecting PoE information via LLDP only affects power delivery; it does not
affect normal Ethernet connectivity.
To enable or disable ports for allocating power using LLDP, use this command.
Syntax: int <port-list> poe-lldp-detect [enabled | disabled]
Enables or disables port(s) for allocating PoE power based on
the link-partner’s capabilities via LLDP.
Default: Disabled
For example, you can enter this command to enable LLDP detection:
ProCurve(config)# int 7 poe-lldp-detect enabled
or in interface context:
ProCurve(eth-7)# poe-lldp-detect enabled
To enable PoE detection via LLDP TLV advertisement, use this command and

Planning and Implementing a PoE Configuration
Planning and Implementing a PoE
Configuration
This section provides an overview of some considerations for planning a PoE
application. For additional information, refer to the HP ProCurve PoE
Planning and Implementation Guide.
Assigning PoE Ports to VLANs
If your network includes VLANs, you may want to assign various PoE-
configured ports to specific VLANs. For example, if you are using PoE
telephones in your network, you may want to assign ports used for telephone
access to a VLAN reserved for telephone traffic.
Applying Security Features to PoE Configurations
You can utilize security features built into the switch to control device or user
access to the network through PoE ports in the same way as non-PoE ports.
■ MAC Address Security: Using Port Security, you can configure each
switch port with a unique list of up to eight MAC addresses for devices
that are authorized to access the network through that port. For more
information, refer to the chapter titled “Configuring and Monitoring
Port Security” in the Access Security Guide for your switch.
■ Username/Password Security: If you are connecting a device that
allows you to enter a username and password that is forwarded to a
networked server for authentication, then you can also configure the
following security features:
– TACACS+
– RADIUS Authentication and Accounting
– 802.1X Authentication
For more information, refer to the Access Security Guide for your switch.

Port trunking allows you to assign up to eight physical links to one logical link
(trunk) that functions as a single, higher-speed link providing dramatically
increased bandwidth. This capability applies to connections between back-
bone devices as well as to connections in other network areas where traffic
bottlenecks exist. A trunk group is a set of up to eight ports configured as
members of the same port trunk. Note that the ports in a trunk group do not
have to be consecutive. For example:
The multiple physical links in a trunk behave as one logical link

12-2
Port Trunking
Overview
Port Connections and Configuration: All port trunk links must be point-
to-point connections between a switch and another switch, router, server, or
workstation configured for port trunking. No intervening, non-trunking
devices are allowed. It is important to note that ports on both ends of a port
trunk group must have the same mode (speed and duplex) and flow control
settings.
Note Link Connections. The switch does not support port trunking through an
intermediate, non-trunking device such as a hub, or using more than one media
type in a port trunk group. Similarly, for proper trunk operation, all links in
the same trunk group must have the same speed, duplex, and flow control.
Port Security Restriction. Port security does not operate on a trunk group.
If you configure port security on one or more ports that are later added to a
trunk group, the switch resets the port security parameters for those ports to
the factory-default configuration.
Caution To avoid broadcast storms or loops in your network while configuring a
trunk, first disable or disconnect all ports you want to add to or remove from
the trunk. After you finish configuring the trunk, enable or re-connect the
ports.

Port Trunking
Port Trunk Features and Operation
Port Trunk Features and Operation
The switches covered in this guide offer these options for port trunking:
■ LACP: IEEE 802.3ad—page 12-18
■ Trunk: Non-Protocol—page 12-26
Up to 24 trunk groups are supported on the switches covered in this guide. The
actual maximum depends on the number of ports available on the switch and
the number of links in each trunk. (Using the Link Aggregation Control
Protocol—LACP—option, you can include standby trunked ports in addition
to the maximum of eight actively trunking ports.)
LACP Note LACP requires full-duplex (FDx) links of the same media type (10/100Base-T,
100FX, etc.) and the same speed, and enforces speed and duplex conformance
across a trunk group. For most installations, ProCurve recommends that you
leave the port Mode settings at Auto (the default). LACP also operates with
Auto-10, Auto-100, and Auto-1000 (if negotiation selects FDx), and 10FDx, 100FDx,
and 1000FDx settings. (The 10-gigabit ports available for some switch models
allow only the Auto setting.)
Fault Tolerance: If a link in a port trunk fails, the switch redistributes
traffic originally destined for that link to the remaining links in the trunk. The
trunk remains operable as long as there is at least one link in operation. If a
link is restored, that link is automatically included in the traffic distribution
again. The LACP option also offers a standby link capability, which enables
you to keep links in reserve for service if one or more of the original active
links fails. Refer to “Trunk Group Operation Using LACP” on page 12-18.)
Trunk Configuration Methods
Dynamic LACP Trunk: The switch automatically negotiates trunked links
between LACP-configured ports on separate devices, and offers one dynamic
trunk option: LACP. To configure the switch to initiate a dynamic LACP trunk
with another device, use the interface command in the CLI to set the default
LACP option to Active on the ports you want to use for the trunk. For example,
the following command sets ports C1-C4 to LACP active:
12-4
Port Trunking
Trunk Configuration Methods
ProCurve(config) int c1-c4 lacp active
Note that the preceding example works if the ports are not already operating
in a trunk. To change the LACP option on ports already operating as a trunk,
you must first remove them from the trunk. For example, if ports C1 - C4 were
LACP-active and operating in a trunk with another device, you would do the
following to change them to LACP-passive:
ProCurve(config)# no int c1-c4 lacp
Removes the ports from the trunk.
ProCurve(config)# int c1-c4 lacp passive
Configures LACP passive.
Static Trunk: The switch uses the links you configure with the Port/Trunk
Settings screen in the menu interface or the trunk command in the CLI to create
a static port trunk. The switch offers two types of static trunks: LACP and
Trunk.

Table 12-2. Trunk Configuration Protocols
Protocol Trunking Options
LACP Provides dynamic and static LACP trunking options.
(802.3ad) • Dynamic LACP — Use the switch-negotiated dynamic LACP trunk when:
– The port on the other end of the trunk link is configured for Active or Passive LACP.
– You want fault-tolerance for high-availability applications. If you use an eight-link trunk you can also
configure one or more additional links to operate as standby links that will activate only if another
active link goes down.
• Static LACP — Use the manually configured static LACP trunk when:
– The port on the other end of the trunk link is configured for a static LACP trunk
– You want to configure non-default spanning tree or IGMP parameters on an LACP trunk group.
– You want an LACP trunk group to operate in a VLAN other than the default VLAN and GVRP is disabled.
(Refer to “VLANs and Dynamic LACP” on page 12-23.)
– You want to use a monitor port on the switch to monitor an LACP trunk.
For more information, refer to “Trunk Group Operation Using LACP” on page 12-18.
Trunk Provides manually configured, static-only trunking to:
(non- • Most ProCurve switches not running the 802.3ad LACP protocol.
protocol) • Windows NT and HP-UX workstations and servers
Use the Trunk option when:
– The device to which you want to create a trunk link is using a non-802.3ad trunking protocol
– You are unsure which type of trunk to use, or the device to which you want to create a trunk link is
using an unknown trunking protocol.
– You want to use a monitor port on the switch to monitor traffic on a trunk.
Refer to “Trunk Group Operation Using the “Trunk” Option” on page 12-26.
12-6
Port Trunking
Trunk Configuration Methods
Table 12-3. General Operating Rules for Port Trunks
Media: For proper trunk operation, all ports on both ends of a trunk group must have the same media type and mode
(speed and duplex). (For the switches covered in this guide, ProCurve recommends leaving the port Mode setting at Auto
or, in networks using Cat 3 cabling, Auto-10.)
Port Configuration: The default port configuration is Auto, which enables a port to sense speed and negotiate duplex with
an Auto-Enabled port on another device. ProCurve recommends that you use the Auto setting for all ports you plan to use
for trunking. Otherwise, you must manually ensure that the mode setting for each port in a trunk is compatible with the
other ports in the trunk.
Recommended Port Mode Setting for LACP
Figure 12-2. Recommended Port Mode Setting for LACP
All of the following operate on a per-port basis, regardless of trunk membership:
• Enable/Disable
• Flow control (Flow Ctrl)
LACP is a full-duplex protocol. Refer to “Trunk Group Operation Using LACP” on page 12-18.
Trunk Configuration: All ports in the same trunk group must be the same trunk type (LACP or Trunk). All LACP ports in the
same trunk group must be either all static LACP or all dynamic LACP.
A trunk appears as a single port labeled Dyn1 (for an LACP dynamic trunk) or Trk1 (for a static trunk of type: LACP,
Trunk) on various menu and CLI screens. For a listing of which screens show which trunk types, refer to “How the Switch
Lists Trunk Data” on page 12-27.
For spanning-tree or VLAN operation, configuration for all ports in a trunk is done at the trunk level. (You cannot separately
configure individual ports within a trunk for spanning-tree or VLAN operation.)
Traffic Distribution: All of the switch trunk protocols use the SA/DA (Source Address/Destination Address) method of
distributing traffic across the trunked links. Refer to “Outbound Traffic Distribution Across Trunked Links” on page 12-27.
12-7
Port Trunking
Trunk Configuration Methods
Spanning Tree: 802.1D (STP) and 802.1w (RSTP) Spanning Tree operate as a global setting on the switch (with one instance
of Spanning Tree per switch). 802.1s (MSTP) Spanning Tree operates on a per-instance basis (with multiple instances
allowed per switch). For each SpanningTree instance, you can adjust Spanning Tree parameters on a per-port basis. A
static trunk of any type appears in the Spanning Tree configuration display, and you can configure Spanning Tree
parameters for a static trunk in the same way that you would configure Spanning Tree parameters on a non-trunked port.
(Note that the switch lists the trunk by name—such as Trk1—and does not list the individual ports in the trunk.) For
example, if ports C1 and C2 are configured as a static trunk named Trk1, they are listed in the Spanning Tree display as
Trk1 and do not appear as individual ports in the Spanning Tree displays.
In this example showing
part of the show spanning-
tree listing, ports C1 and C2
are members of TRK1 and
do not appear as individual
ports in the port
configuration part of the
listing.
Figure 12-3. Example of a Port Trunk in a Spanning Tree Listing
When Spanning Tree forwards on a trunk, all ports in the trunk will be forwarding. Conversely, when Spanning Tree blocks
a trunk, all ports in the trunk are blocked.
Note: A dynamic LACP trunk operates only with the default Spanning Tree settings. Also, this type of trunk appears in
the CLI show spanning-tree display, but not in the Spanning Tree Operation display of the Menu interface.
If you remove a port from a static trunk, the port retains the same Spanning Tree settings that were configured for the trunk.
IP Multicast Protocol (IGMP): A static trunk of any type appears in the IGMP configuration display, and you can configure
IGMP for a static trunk in the same way that you would configure IGMP on a non-trunked port. (Note that the switch lists
the trunk by name—such as Trk1—and does not list the individual ports in the trunk.) Also, creating a new trunk
automatically places the trunk in IGMP Auto status if IGMP is enabled for the default VLAN. A dynamic LACP trunk
operates only with the default IGMP settings and does not appear in the IGMP configuration display or show ip igmp
listing.
VLANs: Creating a new trunk automatically places the trunk in the DEFAULT_VLAN, regardless of whether the ports in
the trunk were in another VLAN. Similarly, removing a port from a trunk group automatically places the port in the default
VLAN. You can configure a static trunk in the same way that you configure a port for membership in any VLAN.
Note: For a dynamic LACP trunk to operate in a VLAN other than the default VLAN (DEFAULT_VLAN), GVRP must be
enabled. Refer to “Trunk Group Operation Using LACP” on page 12-18.
Port Security: Trunk groups (and their individual ports) cannot be configured for port security, and the switch excludes
trunked ports from the show port-security listing. If you configure non-default port security settings for a port, then
subsequently try to place the port in a trunk, you will see the following message and the command will not be executed:
< port-list > Command cannot operate over a logical port.
Monitor Port:
Note: A trunk cannot be a monitor port. A monitor port can monitor a static trunk but cannot monitor a dynamic LACP trunk.

Menu: Viewing and Configuring a Static Trunk Group
• For proper trunk operation, all ports in a trunk must have the same
media type and mode (such as 10/100TX set to 100FDx, or 100FX set
to 100FDx). The flow control settings must also be the same for all
ports in a given trunk. To verify these settings, refer to “Viewing Port
Status and Configuring Port Parameters” on page 10-3.
• You can configure the trunk group with up to eight ports per trunk. If
multiple VLANs are configured, all ports within a trunk will be
assigned to the same VLAN or set of VLANs. (With the 802.1Q VLAN
capability built into the switch, more than one VLAN can be assigned
to a trunk. Refer to the chapter titled “Static Virtual LANs (VLANs)”
in the Advanced Traffic Management Guide for your switch.)
(To return a port to a non-trunk status, keep pressing the Space bar
until a blank appears in the highlighted Group value for that port.)
Figure 12-5. Example of the Configuration for a Two-Port Trunk Group
6. Move the cursor to the Type column for the selected port and use the
Space bar to select the trunk type:
– LACP
– Trunk (the default type if you do not specify a type)
All ports in the same trunk group on the same switch must have the same
Type (LACP or Trunk).
7. When you are finished assigning ports to the trunk group, press [Enter],
then [S] (for Save) and return to the Main Menu. (It is not necessary to
reboot the switch.)
During the Save process, traffic on the ports configured for trunking will
be delayed for several seconds. If the Spanning Tree Protocol is enabled,
the delay may be up to 30 seconds.

CLI: Viewing and Configuring Port Trunk Groups
Using a port list specifies, for switch ports in a static trunk group, only the
ports you want to view. In this case, the command specifies ports A5 through
A7. However, because port A6 is not in a static trunk group, it does not appear
in the resulting listing:
Port A5 appears with an example of a name that you can optionally assign using the Friendly
Port Names feature. (Refer to “Using Friendly (Optional) Port Names” on page 10-23.)
Port A6 does not appear in this listing because
it is not assigned to a static trunk.
Figure 12-6. Example Listing Specific Ports Belonging to Static Trunks
The show trunks < port-list > command in the above example includes a port
list, and thus shows trunk group information only for specific ports that have
membership in a static trunk. In figure 12-7, the command does not include a
port list, so the switch lists all ports having static trunk membership.

Dynamic LACP Standby Links. Dynamic LACP trunking enables you to
configure standby links for a trunk by including more than eight ports in a
dynamic LACP trunk configuration. When eight ports (trunk links) are up, the
remaining link(s) will be held in standby status. If a trunked link that is “Up”
fails, it will be replaced by a standby link, which maintains your intended
bandwidth for the trunk. (Refer to also the “Standby” entry under “Port Status”
in "Table 12-5. LACP Port Status Data" on page 12-21.) In the next example,
ports A1 through A9 have been configured for the same LACP trunk. Notice
that one of the links shows Standby status, while the remaining eight links are
“Up”.

Important Configure port trunking before you connect the trunked links between
switches. Otherwise, a broadcast storm could occur. (If you need to connect
the ports before configuring them for trunking, you can temporarily disable
the ports until the trunk is configured. Refer to “Enabling or Disabling Ports
and Configuring Port Mode” on page 10-16.)
The table on page 12-5 describes the maximum number of trunk groups you
can configure on the switch. An individual trunk can have up to eight links,
with additional standby links if you’re using LACP. You can configure trunk
group types as follows:
Trunk Type Trunk Group Membership
TrkX (Static) DynX (Dynamic)
LACP

The following examples show how to create different types of trunk groups.

CLI: Viewing and Configuring Port Trunk Groups
Configuring a Static Trunk or Static LACP Trunk Group.
Syntax: trunk < port-list > < trk1 ... trk24 > < trunk | lacp >
Configures the specified static trunk type.
This example uses ports C4 - C6 to create a non-protocol static trunk group
with the group name of Trk2.
ProCurve(config)# trunk c4-c6 trk2 trunk
Removing Ports from a Static Trunk Group. This command removes
one or more ports from an existing Trkx trunk group.
Caution Removing a port from a trunk can create a loop and cause a broadcast storm.
When you remove a port from a trunk where spanning tree is not in use,
ProCurve recommends that you first disable the port or disconnect the link
on that port.
Syntax: no trunk < port-list >
Removes the specified ports from an existing trunk group.
For example, to remove ports C4 and C5 from an existing trunk group.
ProCurve(config)# no trunk c4-c5
Enabling a Dynamic LACP Trunk Group. In the default port configura-
tion, all ports on the switch are set to disabled. To enable the switch to
automatically form a trunk group that is dynamic on both ends of the link, the
ports on one end of a set of links must be LACP Active. The ports on the other
end can be either LACP Active or LACP Passive. The active command enables
the switch to automatically establish a (dynamic) LACP trunk group when the
device on the other end of the link is configured for LACP Passive.

(In this case spanning-tree blocking is needed to prevent a loop.
Switch “A”

Switch “B”
with ports set

Dynamic LACP trunk automatically forms because both
ends of the links are LACP and at least one end is LACP
active. (Spanning tree is not needed, and the clear
advantages are increased bandwidth and fault-tolerance.)
Syntax: interface < port-list > lacp active
Configures < port-list > as LACP active. If the ports at the other
end of the links on < port-list > are configured as LACP passive,
then this command enables a dynamic LACP trunk group on
< port-list >.
This example uses ports C4 and C5 to enable a dynamic LACP trunk group.
ProCurve(config)# interface c4-c5 lacp active
Removing Ports from an Dynamic LACP Trunk Group. To remove a
port from dynamic LACP trunk operation, you must turn off LACP on the port.
(On a port in an operating, dynamic LACP trunk, you cannot change between
LACP Active and LACP passive without first removing LACP operation from
the port.)

Port Trunking
Web: Viewing Existing Port Trunk Groups
Caution Unless spanning tree is running on your network, removing a port from a trunk
can result in a loop. To help prevent a broadcast storm when you remove a
port from a trunk where spanning tree is not in use, ProCurve recommends
that you first disable the port or disconnect the link on that port.
Syntax: no interface < port-list > lacp
Removes < port-list > from any dynamic LACP trunk and
returns the ports in < port-list > to passive LACP.
In this example, port C6 belongs to an operating, dynamic LACP trunk. To
remove port C6 from the dynamic trunk and return it to passive LACP, you
would do the following:
ProCurve(config)# no interface c6 lacp
ProCurve(config)# interface c6 lacp passive
Note that in the above example, if the port on the other end of the link is
configured for active LACP or static LACP, the trunked link will be re-
established almost immediately.

Trunk Group Operation Using LACP
Trunk Group Operation Using LACP
The switch can automatically configure a dynamic LACP trunk group or you
can manually configure a static LACP trunk group.
Note LACP requires full-duplex (FDx) links of the same media type (10/100Base-T,
100FX, etc.) and the same speed, and enforces speed and duplex conformance
across a trunk group. For most installations, ProCurve recommends that you
leave the port Mode settings at Auto (the default). LACP also operates with
Auto-10, Auto-100, and Auto-1000 (if negotiation selects FDx), and 10FDx, 100FDx,
and 1000FDx settings.
LACP trunk status commands include:
Trunk Display Method Static LACP Trunk Dynamic LACP Trunk
CLI show lacp command Included in listing. Included in listing.

operate as described in table 12-4 on the next page.

Trunk Group Operation Using LACP
Table 12-4. LACP Trunk Types
LACP Port Trunk
Configuration
Operation
Dynamic LACP This option automatically establishes an 802.3ad-compliant trunk group, with LACP for the port Type
parameter and DynX for the port Group name, where X is an automatically assigned value from 1 to 24,
depending on how many dynamic and static trunks are currently on the switch. (The switch allows a
maximum of 24 trunk groups in any combination of static and dynamic trunks.)
Note: Dynamic LACP trunks operate only in the default VLAN (unless GVRP is enabled and Forbid is
used to prevent the trunked ports from joining the default VLAN). Thus, if an LACP dynamic port
forms using ports that are not in the default VLAN, the trunk will automatically move to the default
VLAN unless GVRP operation is configured to prevent this from occurring. In some cases, this can
create a traffic loop in your network. For more on this topic, refer to “VLANs and Dynamic LACP” on
page 12-23.
Under the following conditions, the switch automatically establishes a dynamic LACP port trunk group
and assigns a port Group name:
• The ports on both ends of each link have compatible mode settings (speed and duplex).
• The port on one end of each link must be configured for LACP Active and the port on the other end
of the same link must be configured for either LACP Passive or LACP Active. For example:
Switch 1
Port X:
LACP Enable: Active
Port Y:
LACP Enable: Active
Switch 2
Port A:
LACP Enable: Active
Port B:
LACP Enable: Passive
Active-to-Active
Active-to-Passive
Either of the above link configurations allow a dynamic LACP trunk link.
Backup Links: A maximum of eight operating links are allowed in the trunk, but, with dynamic LACP,
you can configure one or more additional (backup) links that the switch automatically activates if a
primary link fails. To configure a link as a standby for an existing eight-port dynamic LACP trunk, ensure
that the ports in the standby link are configured as either active-to-active or active-to-passive between
switches.
Displaying Dynamic LACP Trunk Data: To list the configuration and status for a dynamic LACP trunk,
use the CLI show lacp command.
Note: The dynamic trunk is automatically created by the switch, and is not listed in the static trunk
listings available in the menu interface or in the CLI show trunk listing.

Port Trunking
Trunk Group Operation Using LACP
Static LACP Provides a manually configured, static LACP trunk to accommodate these conditions:
LACP Port Trunk
Configuration
Operation
• The port on the other end of the trunk link is configured for a static LACP trunk.
• You want to configure non-default spanning tree or IGMP parameters on an LACP trunk group.
• You want an LACP trunk group to operate in a VLAN other than the default VLAN and GVRP is
disabled. (Refer to “VLANs and Dynamic LACP” on page 12-23.)
• You want to use a monitor port on the switch to monitor an LACP trunk.
The trunk operates if the trunk group on the opposite device is running one of the following trunking
protocols:
• Active LACP
• Passive LACP
• Trunk
This option uses LACP for the port Type parameter and TrkX for the port Group parameter, where X is
an automatically assigned value in a range corresponding to the maximum number of trunks the switch
allows. (The table on page 12-5 lists the maximum number of trunk groups allowed on the switches
covered in this guide.)
Displaying Static LACP Trunk Data: To list the configuration and status for a static LACP trunk, use the
CLI show lacp command. To list a static LACP trunk with its assigned ports, use the CLI show trunk
command or display the menu interface Port/Trunk Settings screen.
Static LACP does not allow standby ports.
12-20
Port Trunking
Trunk Group Operation Using LACP
Default Port Operation
In the default configuration, LACP is disabled for all ports. If LACP is not
configured as Active on at least one end of a link, then the port does not try
to detect a trunk configuration and operates as a standard, untrunked port.
Table 12-5 lists the elements of per-port LACP operation. To display this data
for a switch, execute the following command in the CLI:
ProCurve> show lacp
Table 12-5. LACP Port Status Data
Status Name Meaning
Port Numb Shows the physical port number for each port configured for LACP operation (C1, C2, C3 …). Unlisted port
numbers indicate that the missing ports are assigned to a static Trunk group are not configured for any
trunking.
LACP Enabled Active: The port automatically sends LACP protocol packets.
Passive: The port does not automatically send LACP protocol packets, and responds only if it receives
LACP protocol packets from the opposite device.
A link having either two active LACP ports or one active port and one passive port can perform dynamic
LACP trunking. A link having two passive LACP ports will not perform LACP trunking because both ports
are waiting for an LACP protocol packet from the opposite device.
Note: In the default switch configuration, LACP is disabled for all ports.
Trunk Group TrkX: This port has been manually configured into a static LACP trunk.
Trunk Group Same as Port Number: The port is configured for LACP, but is not a member of a port trunk.
Port Status Up: The port has an active LACP link and is not blocked or in Standby mode.
Down: The port is enabled, but an LACP link is not established. This can indicate, for example, a port that
is not connected to the network or a speed mismatch between a pair of linked ports.
Disabled: The port cannot carry traffic.
Blocked: LACP, spanning tree has blocked the port. (The port is not in LACP Standby mode.) This may
be due to a (brief) trunk negotiation or a configuration error such as differing port speeds on the same
link or trying to connect the switch to more trunks than it can support. (See the table on page 12-5.)
Note: Some older devices are limited to four ports in a trunk. When eight LACP-enabled ports are
connected to one of these older devices, four ports connect, but the other four ports are blocked.
Standby: The port is configured for dynamic LACP trunking to another device, but the maximum number
of ports for the Dynamic trunk to that device has already been reached on either the switch or the other
device. This port will remain in reserve, or “standby” unless LACP detects that another, active link in the
trunk has become disabled, blocked, or down. In this case, LACP automatically assigns a Standby port,
if available, to replace the failed port.
12-21
Port Trunking
Trunk Group Operation Using LACP
LACP Partner Yes: LACP is enabled on both ends of the link.
Status Name Meaning
No: LACP is enabled on the switch, but either LACP is not enabled or the link has not been detected on
the opposite device.
LACP Status Success: LACP is enabled on the port, detects and synchronizes with a device on the other end of the
link, and can move traffic across the link.
Failure: LACP is enabled on a port and detects a device on the other end of the link, but is not able to
synchronize with this device, and therefore not able to send LACP packets across the link. This can be
caused, for example, by an intervening device on the link (such as a hub), a bad hardware connection,
or if the LACP operation on the opposite device does not comply with the IEEE 802.3ad standard.
LACP Notes and Restrictions
802.1X (Port-Based Access Control) Configured on a Port. To main-
tain security, LACP is not allowed on ports configured for 802.1X authenticator
operation. If you configure port security on a port on which LACP (active or
passive) is configured, the switch removes the LACP configuration, displays
a notice that LACP is disabled on the port(s), and enables 802.1X on that port.
ProCurve(config)# aaa port-access authenticator b1
LACP has been disabled on 802.1x port(s).
ProCurve(config)#
The switch will not allow you to configure LACP on a port on which port
access (802.1X) is enabled. For example:
ProCurve(config)# int b1 lacp passive
Error configuring port < port-number >: LACP and 802.1x
cannot be run together.
ProCurve(config)#
To restore LACP to the port, you must first remove the port’s 802.1X configu-
ration and then re-enable LACP active or passive on the port.
Port Security Configured on a Port. To maintain security, LACP is not
allowed on ports configured for port security. If you configure port security
on a port on which LACP (active or passive) is configured, the switch removes
the LACP configuration, displays a notice that LACP is disabled on the port(s),
and enables port security on that port. For example:
ProCurve(config)# port-security a17 learn-mode static
address-limit 2
LACP has been disabled on secured port(s).
ProCurve(config)#
12-22
Port Trunking
Trunk Group Operation Using LACP
The switch will not allow you to configure LACP on a port on which port
security is enabled. For example:
ProCurve(config)# int a17 lacp passive
Error configuring port A17: LACP and port security cannot
be run together.
ProCurve(config)#
To restore LACP to the port, you must remove port security and re-enable
LACP active or passive.
Changing Trunking Methods. To convert a trunk from static to dynamic,
you must first eliminate the static trunk.
Static LACP Trunks. Where a port is configured for LACP (Active or
Passive), but does not belong to an existing trunk group, you can add that port
to a static trunk. Doing so disables dynamic LACP on that port, which means
you must manually configure both ends of the trunk.
Dynamic LACP Trunks. You can configure a port for LACP-active or LACP-
passive, but on a dynamic LACP trunk you cannot configure the other options
that you can on static trunks. If you want to manually configure a trunk, use
the trunk command. (Refer to “Using the CLI To Configure a Static or Dynamic
Trunk Group” on page 12-14.)
VLANs and Dynamic LACP. A dynamic LACP trunk operates only in the
default VLAN (unless you have enabled GVRP on the switch and use Forbid to
prevent the ports from joining the default VLAN).
■ If you want to use LACP for a trunk on a non-default VLAN and GVRP is
disabled, configure the trunk as a static trunk.
12-23
Port Trunking
Trunk Group Operation Using LACP
Blocked Ports with Older Devices. Some older devices are limited to four
ports in a trunk. When eight LACP-enabled ports are connected to one of these
older devices, four ports connect, but the other four ports are blocked. The
LACP status of the blocked ports is shown as “Failure”.
If one of the other ports becomes disabled, a blocked port will replace it (Port
Status becomes “Up”). When the other port becomes active again, the replace-
ment port goes back to blocked (Port Status is “Blocked”). It can take a few
seconds for the switch to discover the current status of the ports.

Port Trunking
Trunk Group Operation Using LACP
■ If there are ports that you do not want on the default VLAN, ensure that
they cannot become dynamic LACP trunk members. Otherwise a traffic
loop can unexpectedly occur. For example:
VLAN-1
(Default
VLAN)
VLAN-2
VLAN-1
(Default
VLAN)
VLAN-2
VLAN-1
(Default
VLAN)
VLAN-2
VLAN-1
(Default
VLAN)
VLAN-2
If the ports in VLAN 2 are configured to allow a dynamic trunk (and GVRP is disabled), adding a
second link in VLAN 2 automatically forms a dynamic LACP trunk and moves the trunk to VLAN-1
(the default VLAN), which creates a traffic loop in VLAN 1 between the two switches and
eliminates the link in VLAN 2 between the two switches.
Figure 12-12. A Dynamic LACP Trunk Forming in a VLAN Can Cause a Traffic Loop
Easy control methods include either disabling LACP on the selected ports or
configuring them to operate in static LACP trunks.
Spanning Tree and IGMP. If Spanning Tree and/or IGMP is enabled in the
switch, a dynamic LACP trunk operates only with the default settings for these
features and does not appear in the port listings for these features.
Half-Duplex and/or Different Port Speeds Not Allowed in LACP
Trunks. The ports on both sides of an LACP trunk must be configured for
the same speed and for full-duplex (FDx). The 802.3ad LACP standard speci-
fies a full-duplex (FDx) requirement for LACP trunking. (10-gigabit ports
operate only at FDx.)
A port configured as LACP passive and not assigned to a port trunk can be
configured to half-duplex (HDx). However, in any of the following cases, a
port cannot be reconfigured to an HDx setting:
■ If the port is a 10-gigabit port.
■ If a port is set to LACP Active, you cannot configure it to HDx.
■ If a port is already a member of a static or dynamic LACP trunk, you cannot
configure it to HDx.
■ If a port is already set to HDx, the switch does not allow you to configure
it for a static or dynamic LACP trunk.
12-25
Port Trunking
Trunk Group Operation Using the “Trunk” Option
Dynamic/Static LACP Interoperation: A port configured for dynamic
LACP can properly interoperate with a port configured for static (TrkX) LACP,
but any ports configured as standby LACP links will be ignored.
Trunk Group Operation Using the
“Trunk” Option
This method creates a trunk group that operates independently of specific
trunking protocols and does not use a protocol exchange with the device on
the other end of the trunk. With this choice, the switch simply uses the SA/DA
method of distributing outbound traffic across the trunked ports without
regard for how that traffic is handled by the device at the other end of the
trunked links. Similarly, the switch handles incoming traffic from the trunked
links as if it were from a trunked source.
When a trunk group is configured with the trunk option, the switch automati-
cally sets the trunk to a priority of “4” for spanning-tree operation (even if
spanning-tree is currently disabled. This appears in the running-config file as
spanning-tree Trkn priority 4. Executing write memory after config-
uring the trunk places the same entry in the startup-config file.
Use the Trunk option to establish a trunk group between a switch covered in
thisguide and another device, where the other device’s trunking operation fails
to operate properly with LACP trunking configured on the switches.

Outbound Traffic Distribution Across
Trunked Links
The two trunk group options (LACP and Trunk) use source-destination
address pairs (SA/DA) for distributing outbound traffic over trunked links.
SA/DA (source address/destination address) causes the switch to distribute
outbound traffic to the links within the trunk group on the basis of source/
destination address pairs. That is, the switch sends traffic from the same
source address to the same destination address through the same trunked link,
and may also send traffic from the same source address to a different desti-
nation address through the same link or a different link, depending on the
mapping of path assignments among the links in the trunk. Likewise, the
switch distributes traffic for the same destination address but from different
source addresses through links depending on the path assignment.
12-27
Port Trunking
Outbound Traffic Distribution Across Trunked Links
The load-balancing is done on a per communication basis. Otherwise, traffic
is transmitted across the same path as shown in figure 12-13. That is, if Client
A attached to Switch 1 sends five packets of data to Server A attached to
Switch 2, the same link is used to send all five packets. The SA/DA address
pair for the traffic is the same. The packets are not evenly distributed across
any other existing links between the two switches; they all take the same path.
Client A Client B
Switch 1 Switch 2
All five packets go through
the same link
Figure 12-13. Example of Single Path Traffic through a Trunk
The actual distribution of the traffic through a trunk depends on a calculation
using bits from the Source Address and Destination address. When an IP
address is available, the calculation includes the last five bits of the IP source
address and IP destination address, otherwise the MAC addresses are used.
The result of that process undergoes a mapping that determines which link
the traffic goes through. If you have only two ports in a trunk, it is possible
that all the traffic will be sent through one port even if the SA/DA pairs are
different. The more ports you have in the trunk, the more likely it is that the
traffic will be distributed among the links.
When a new port is added to the trunk, the switch begins sending traffic, either
new traffic or existing traffic, through the new link. As links are added or
deleted, the switch redistributes traffic across the trunk group. For example,
in figure 12-14 showing a three-port trunk, traffic could be assigned as shown
in table 12-6.
Switch Switch

B X

Source: Destination: Link:
Node A Node W 1
Node B Node X 2
Node C Node Y 3
Node D Node Z 1
Node A Node Y 2
Node B Node W 3
Because the amount of traffic coming from or going to various nodes in a
network can vary widely, it is possible for one link in a trunk group to be fully
utilized while other links in the same trunk have unused bandwidth capacity
even if the assignments were evenly distributed across the links in a trunk.

Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
Using SNMP Tools To Manage the Switch
Overview
You can manage the switch via SNMP from a network management station
running an application such as ProCurve Manager (PCM) or ProCurve
Manager Plus (PCM+). For more on PCM and PCM+, visit the ProCurve
Networking web site at:
www.procurve.com
Click on products index in the sidebar, then click on the appropriate link
appearing under the Network Management heading.
This section includes:
■ An overview of SNMP management for the switch
■ Configuring the switches for:
• SNMP Communities (page 13-11)
• Trap Receivers and Authentication Traps (page 13-17)
■ Information on advanced management through RMON Support (page
13-33)
To implement SNMP management, the switch must have an IP address,
configured either manually or dynamically (using DHCP or Bootp). If multiple
VLANs are configured, each VLAN interface should have its own IP address.
For DHCP use with multiple VLANs, refer to the section titled “The Primary
VLAN” in the “Static Virtual LANs (VLANs)” chapter of the Advanced Traffic
Management Guide for your switch.
Note If you use the switch’s Authorized IP Managers and Management VLAN
features, ensure that the SNMP management station and/or the choice of
switch port used for SNMP access to the switch are compatible with the access
controls enforced by these features. Otherwise, SNMP access to the switch
will be blocked. For more on Authorized IP Managers, refer to the Access
Security Guide for your switch. (The latest version of this guide is available
on the ProCurve Networking web site.) For information on the Management
VLAN feature, refer to the section titled “The Secure Management VLAN” in
the “Static Virtual LANs (VLANs)” chapter of the Advanced Traffic
Management Guide for your switch.
13-3
Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
SNMP Management Features
SNMP management features on the switch include:
■ SNMP version 1, version 2c, or version 3 over IP
■ Security via configuration of SNMP communities (page 13-11)
■ Security via authentication and privacy for SNMP Version 3 access
■ Event reporting via SNMP
• Version 1 traps
• RMON: groups 1, 2, 3, and 9
■ ProCurve Manager/Plus support
■ Standard MIBs, such as the Bridge MIB (RFC 1493), Ethernet MAU MIB
(RFC 1515), and others.
The switch SNMP agent also uses certain variables that are included in a
Hewlett-Packard proprietary MIB (Management Information Base) file. If you
are using HP OpenView, you can ensure that it is using the latest version of
the MIB file by downloading the file to the OpenView database. To do so, go
to the ProCurve Networking web site at:
www.procurve.com
Click on software updates, then MIBs.
Configuring for SNMP version 1 and 2c Access to the
Switch
SNMP access requires an IP address and subnet mask configured on the
switch. (Refer to “IP Configuration” on page 8-2.) If you are using DHCP/Bootp
to configure the switch, ensure that the DHCP/Bootp process provides the IP
address. (Refer to “DHCP/Bootp Operation” on page 8-12.)
Once an IP address has been configured, the main steps for configuring SNMP
version 1 and version 2c access management features are:
1. Configure the appropriate SNMP communities. (Refer to “SNMPv3 Com-
munities” on page 13-11.)
2. Configure the appropriate trap receivers. (Refer to “SNMP Notifications”
on page 13-17.)
In some networks, authorized IP manager addresses are not used. In this case,
all management stations using the correct community name may access the
switch with the View and Access levels that have been set for that community.
13-4
Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
If you want to restrict access to one or more specific nodes, you can use the
switch’s IP Authorized Manager feature. (Refer to the Access Security Guide
for your switch.)
Caution For ProCurve Manager (PCM) version 1.5 or earlier (or any TopTools version),
deleting the “public” community disables some network management
functions (such as traffic monitoring, SNMP trap generation, and threshold
setting). If network management security is a concern, and you are using the
above software versions, ProCurve recommends that you change the write
access for the “public” community to “Restricted”.
Configuring for SNMP Version 3 Access to the Switch
SNMP version 3 (SNMPv3) access requires an IP address and subnet mask
configured on the switch. (Refer to “IP Configuration” on page 8-2.) If you are
using DHCP/Bootp to configure the switch, ensure that the DHCP/Bootp
process provides the IP address. (See “DHCP/Bootp Operation” on page 8-12.)
Once an IP address has been configured, the main steps for configuring SNMP
version 3 access management features are:
1. Enable SNMPv3 for operation on the switch (Refer to “SNMP Version 3
Commands” on page 13-6)
2. Configure the appropriate SNMP users (Refer to “SNMPv3 Users” on page
13-7)
3. Configure the appropriate SNMP communities. (Refer to “SNMPv3 Com-
munities” on page 13-11.)
4. Configure the appropriate trap receivers. (Refer to “SNMP Notifications”
on page 13-17.)
In some networks, authorized IP manager addresses are not used. In this case,
all management stations using the correct User and community name may
access the switch with the View and Access levels that have been set for that
community. If you want to restrict access to one or more specific nodes, you
can use the switch’s IP Authorized Manager feature. (Refer to the Access
Security Guide for your switch.)

SNMP Version 3 Commands
SNMP version 3 (SNMPv3) adds some new commands to the CLI for
configuring SNMPv3 functions. To enable SMNPv3 operation on the switch,
use the snmpv3 enable command. An initial user entry will be generated with
MD5 authentication and DES privacy.
You may (optionally) restrict access to only SNMPv3 agents by using the
snmpv3 only command. To restrict write-access to only SNMPv3 agents, use
the snmpv3 restricted-access command.
Caution Restricting access to only version 3 messages will make the community named
“public” inaccessible to network management applications (such as auto-
discovery, traffic monitoring, SNMP trap generation, and threshold setting)
from operating in the switch.
Syntax: [no] snmpv3 enable
Enable and disable the switch for access from SNMPv3
agents. This includes the creation of the initial user record.
[no] snmpv3 only
Enables or disables restrictions to access from only SNMPv3
agents. When enabled, the switch will reject all non-SNMPv3
messages.
[no] snmpv3 restricted-access
Enables or disables restrictions from all non-SNMPv3 agents
to read only access.
show snmpv3 enable
Displays the operating status of SNMPv3.
show snmpv3 only
Displays status of message reception of non-SNMPv3
messages.
show snmpv3 restricted-access

Enabling SNMPv3
The snmpv3 enable command allows the switch to:
■ Receive SNMPv3 messages.
■ Configure initial users.
■ Restrict non-version 3 messages to “read only” (optional).
Figure 13-1 shows an example of how to use the snmpv3 enable command.

To create new users, most SNMPv3 management software requires an initial
user record to clone. The initial user record can be downgraded and provided
with fewer features, but not upgraded by adding new features. For this reason
it is recommended that when you enable SNMPv3, you also create a second
user with SHA authentication and DES privacy.

2. Assign users to Security Groups based on their security model with the
snmpv3 group command (see “Assigning Users to Groups” on page 13-10).
Caution If you add an SNMPv3 user without authentication and/or privacy to a group
that requires either feature, the user will not be able to access the switch.
Ensure that you add a user with the appropriate security level to an existing
security group.
Adding Users. To configure an SNMPv3 user, you must first add the user

Using SNMP requires that the switch have an IP address and subnet mask
compatible with your network.
Caution For ProCurve Manager (PCM) version 1.5 or earlier (or any TopTools version),
deleting the “public” community disables some network management
functions (such as traffic monitoring, SNMP trap generation, and threshold
setting). If network management security is a concern, and you are using the

SNMP Notifications
The switches covered in this guide support:
■ SNMP version 1 or SNMP version 2c traps
■ SNMPv2c informs
■ SNMPv3 notification process, including traps
This section describes how to configure a switch to send network security and
link-change notifications to configured trap receivers.
Supported Notifications
By default, the following notifications are enabled on a switch:
■ Manager password changes
■ SNMP authentication failure
■ Link-change traps: when the link on a port changes from up to down
(linkDown) or down to up (linkUp)
■ Port-security (web, MAC, or 802.1X) authentication failure
■ Invalid password entered in a login attempt through a direct serial, Telnet,
or SSH connection
■ Inability to establish a connection with the RADIUS or TACACS+ authen-
tication server
■ DHCP snooping events
■ ARP protection events
In addition, you can enable the switch to send the following types of
notifications to configured trap receivers. For information on how to
configure each notification, refer to the ProCurve software guide under which
the notification is listed.
■ Management and Configuration Guide:
• Configuration changes
• Link-Layer Discovery Protocol (LLDP)

General Steps for Configuring SNMP Notifications
To configure SNMP notifications, follow these general steps:
1. Determine the versions of SNMP notifications that you want to use in your
network.
If you want to use SNMPv1 and SNMPv2c traps, you must also configure
a trap receiver. Refer to the following sections and follow the required
configuration procedures:
• “SNMPv1 and SNMPv2c Traps” on page 13-19
• “Configuring an SNMP Trap Receiver” on page 13-19
• “Enabling SNMPv2c Informs” on page 13-21
If you want to use SNMPv3 notifications (including traps), you must also
configure an SNMPv3 management station. Follow the required configu-
ration procedure in the following section:
• “Configuring SNMPv3 Notifications” on page 13-23
2. To reconfigure any of the SNMP notifications that are enabled by default
to be sent to a management station (trap receiver), refer to these sections:
• “Enabling Link-Change Traps” on page 13-28
3. (Optional) Refer to the following sections to configure optional SNMP
notification features and verify the current configuration:
• “Configuring the Source IP Address for SNMP Notifications” on page
13-29
• “Displaying SNMP Notification Configuration” on page 13-31
13-18
Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
SNMPv1 and SNMPv2c Traps
The switches covered in this guide support the following functionality from
earlier SNMP versions (SNMPv1 and SNMPv2c):
■ Trap receivers: A trap receiver is a management station to which the
switch sends SNMP traps and (optionally) event log messages sent from
the switch. From the CLI you can configure up to ten SNMP trap receivers
to receive SNMP traps from the switch.
■ Fixed or “Well-Known” Traps: A switch automatically sends fixed traps
(such as “coldStart”, “warmStart”, “linkDown”, and “linkUp”) to trap
receivers using a public or non-public community name.
■ Thresholds: A switch automatically sends all messages created when a
system threshold is reached to the network management station that
configured the threshold, regardless of the trap receiver configuration.
Configuring an SNMP Trap Receiver
Use the snmp-server host command to configure a trap receiver that can receive
SNMPv1 and SNMPv2c traps, and (optionally) event log messages. When you
configure a trap receiver, you specify its community membership,
management station IP address, and (optionally) the type of event log
messages to be sent.
If you specify a community name that does not exist—that is, has not yet been
configured on the switch—the switch still accepts the trap receiver
assignment. However, no traps will be sent to that trap receiver until the
community to which it belongs has been configured on the switch.
13-19
Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
Syntax: snmp-server host <ipv4-addr | ipv6-addr> <community name>
Configures a destination network management station
to receive SNMPv1/v2c traps, and (optionally) event log
messages sent as traps from the switch, using the
specified community name and destination IPv4 or
IPv6 address. You can specify up to ten trap receivers
(network management stations). The default
community name is public.
[<none | all | non-info | critical | debug>]
(Optional) Configures the security level of the event log
messages you want to send as traps to a trap receiver
(see table 13-1, “Security Levels for Event Log Messages
Sent as Traps”).
• The type of event log message that you specify applies
only to event log messages, not to threshold traps.
• For each configured event level, the switch continues
to send threshold traps to all network management
stations that have the appropriate threshold level
configured.
• If you do not specify an event level, the switch uses
the default value (none) and sends no event log
messages as traps.
[<inform>]
(Optional) Configures the switch to send SNMPv2
inform requests when certain events occur. See
“Enabling SNMPv2c Informs” on page 13-21 for more
information.
Table 13-1. Security Levels for Event Log Messages Sent as Traps
Security Level Action
None (default) Sends no event log messages.
All Sends all event log messages.
Non-Info Sends all event log messages that are not for information only.
Critical Sends only event log messages for critical error conditions.
Debug Sends only event log messages needed to troubleshoot network- and
switch-level problems.
13-20
Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
For example, to configure a trap receiver in a community named "red-team"
with an IP address of 10.28.227.130 to receive only "critical" event log
messages, you can enter the following command:
ProCurve(config)# snmp-server host 10.28.227.130 red-team
critical
Notes To replace one community name with another for the same IP address, you
must first enter the no snmp-server host < community-name> <ipv4-address | ipv6-
address > command to delete the unwanted community name. Otherwise, if
you add a new community name with an IP address that is already used with
a different community name, two valid community name entries are created
for the same management station.
If you do not specify the event level ([<none | all | non-info | critical | debug>]),
the switch does not send event log messages as traps. However, "well-known"
traps and threshold traps (if configured) are still sent.
Enabling SNMPv2c Informs
On a switch enabled for SNMPv2c, you can use the snmp-server host inform
command to send inform requests when certain events occur. When an SNMP
Manager receives an inform request, it can send an SNMP response back to
the sending agent on the switch to let the agent know that the inform request
reached its destination.
If the sending agent on the switch does not receive an SNMP response back
from the SNMP Manager within the timeout period, the inform request may
be resent, based on the retry count value.
When you enable SNMPv2c inform requests to be sent, you must specify the
IP address and community name of the management station that will receive
the inform notification.
Syntax: [no] snmp-server host <ipv4-addr | ipv6-addr> <community name>
inform [retries <count>] [timeout <interval>]]
Enables (or disables) the inform option for SNMPv2c on the
switch and allows you to configure options for sending
SNMP inform requests.
retries: Maximum number of times to resend an inform
request if no SNMP response is received. Default: 3
timeout: Number of seconds to wait for an acknowledgement
before resending the inform request. Default: 15 seconds

Configuring SNMPv3 Notifications
The SNMPv3 notification process allows messages that are passed via SNMP
between the switch and a network management station to be authenticated
and encrypted.
To configure SNMPv3 notifications, follow these steps:
1. Enable SNMPv3 operation on the switch by entering the snmpv3 enable
command (see “SNMP Version 3 Commands” on page 13-6).
When SNMPv3 is enabled, the switch supports:
• Reception of SNMPv3 notification messages (traps and informs)
• Configuration of initial users
• (Optional) Restriction of non-SNMPv3 messages to “read only”
2. Configure SNMPv3 users by entering the snmpv3 user command (see
“SNMPv3 Users” on page 13-7). Each SNMPv3 user configuration is
entered in the User Table.
3. Assign SNMPv3 users to security groups according to their level of access
privilege by entering the snmpv3 group command (see “Assigning Users to
Groups” on page 13-10).
4. Define the name of an SNMPv3 notification configuration by entering the
snmpv3 notify command.
Syntax: [no] snmpv3 notify <notify_name> tagvalue <tag_name>
Associates the name of an SNMPv3 notification
configuration with a tag name used (internally) in
SNMPv3 commands. To delete a notification-to-tag
mapping, enter no snmpv3 notify <notify_name>.
notify < notify_name >
Specifies the name of an SNMPv3 notification
configuration.
tagvalue < tag_name >
Specifies the name of a tag value used in other SNMPv3
commands, such as snmpv3 targetaddress params taglist
<tag_name> in Step 5.

Specifies the SNMPv3 notifications (identified by one
or more <tag_name> values) to be sent to the IP address
of the SNMPv3 management station.
You can enter more than one <tag_name> value. Each
<tag_name> value must be already associated with the
name of an SNMPv3 notification configuration entered
with the snmpv3 notify command in Step 4.
Use a blank space to separate <tag_name> values.
You can enter up to 103 characters in <tag_name>

6. Create a configuration record for the target address with the snmpv3
params command.
Syntax [no] snmpv3 params <params_name> user <user_name>
Applies the configuration parameters and IP address
of an SNMPv3 management station (from the params
<params_name> value configured with the snmpv3
targetaddress command in Step 5) to a specified
SNMPv3 user (from the user <user_name> value
configured with the snmpv3 user command in Step 2).
If you enter the snmpv3 params user command, you must
also configure a security model (sec-model) and
message processing algorithm (msg-processing).
< sec-model < ver1 | ver2c | ver3 >
Configures the security model used for SNMPv3
notification messages sent to the management station
configured with the snmpv3 targetaddress command in
Step 5.
If you configure the security model as ver3, you must
also configure the message processing value as ver3.
< msg-processing < ver1 | ver2c | ver3 > [noaut | auth | priv]
Configures the algorithm used to process messages sent
to the SNMPv3 target address.
If you configure the message processing value as ver3
and the security model as ver3, you must also configure
a security services level (noauth, auth, or priv).

Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
An example of how to configure SNMPv3 notification is shown here:
The tag _name value in snmpv3 notify command matches the
tag _name value in the snmpv3 targetaddress command.
Params _name value in the snmpv3 targetaddress command
matches the params _name value in the snmpv3 params
command.
Configuring the security model ver3 requires you to configure
message processing ver3 and a security service level.

Managing Network Security Notifications
By default, a switch is enabled to send the SNMP notifications listed in
“Supported Notifications” on page 13-17 when a network security event (for
example, authentication failure) occurs. However, before security
notifications can be sent, you must first configure one or more trap receivers
or SNMPv3 management stations as described in:
■ “Configuring an SNMP Trap Receiver” on page 13-19
■ “Configuring SNMPv3 Notifications” on page 13-23
You can manage the default configuration of the switch to disable and re-
enable notifications to be sent for the following types of security events:
■ ARP protection events
■ Unable to establish a connection with the RADIUS or TACACS+ authen-
tication server
■ DHCP snooping events
■ Link change notification
■ Invalid password entered in a login attempt through a direct serial, Telnet,
or SSH connection
■ Manager password changes
■ Port-security (web, MAC, or 802.1X) authentication failure
■ SNMP authentication failure

Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
To enable or disable notification/traps for network security failures and other
security events, enter the snmp-server enable traps command.
Syntax: [no] snmp-server enable traps [snmp-auth | password-change-mgr | login-
failure-mgr | port-security | auth-server-fail | link-change]
Enables or disables sending one of the security notification
types listed below to configured trap receivers. (Unless
otherwise stated, all of the following notifications are
enabled in the default configuration.
• auth-server-fail sends a trap if the connection with a RADIUS or
TACACS+ authentication server fails.
• link-change < port-list > sends a trap when the link state on a port
changes from up to down, or the reverse.
• login-failure-mgr sends a trap for a failed login with a manager
password.
• password-change-mgr sends a trap when a manager password is
reset.
• port-security sends a trap for a failed authentication attempt through
a web, MAC, or 801.X authentication session.
• snmp-authentication [ extended | standard ] sends a trap for a failed
authentication attempt via SNMP. Default: extended.
To determine the specific cause of a security event, check the event log in the
console interface to see why a trap was sent. For more information, refer to
“Using the Event Log for Troubleshooting Switch Problems” on page C-22.

Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
Configuring the Source IP Address for SNMP Notifications
The switch uses an interface IP address as the source IP address in IP headers
when sending SNMP notifications (traps and informs) or responses to SNMP
requests.
For multi-netted interfaces, the source IP address is the IP address of the
outbound interface of the SNMP reply, which may differ from the destination
IP address in the IP header of the received request. For security reasons, it
may be desirable to send an SNMP reply with the IP address of the destination
interface (or a specified IP address) on which the corresponding SNMP
request was received.
To configure the switch to use the source IP address on which an SNMP
request was received in SNMP notification/traps and replies, enter the snmp-
server response-source and snmp-server trap-source commands.
Syntax: [no] snmp-server response-source [dst-ip-of-request | <ip-addr>]
Specifies the source IP address of the SNMP response PDU.
The default SNMP response PDU uses the IP address of the
active interface from which the SNMP response was sent as
the source IP address.
The no form of the command resets the switch to the default
behavior (compliant with rfc-1517).
Default: Interface IP address
dst-ip-of-request: Destination IP address of the SNMP request
PDU that is used as the source IP address in an SNMP
response PDU.
<ip-addr>: User-defined interface IP address that is used as
the source IP address in an SNMP response PDU.
For example, to use the IP address of the destination interface on which an
SNMP request was received as the source IP address in the IP header of SNMP
traps and replies, enter the following command:
ProCurve(config)# snmp-server response-source
dst-ip-of-request

Configuring for Network Management Applications
Using SNMP Tools To Manage the Switch
To configure the switch to use a specified source IP address in generated trap
PDUs, enter the snmp-server trap-source command.
Syntax: [no] snmp-server trap-source [<ipv4-addr >]
Specifies the source IP address to be used for a trap PDU.
The no form of the command resets the switch to the default
behavior (compliant with rfc-1517).
Default: Use the interface IP address in generated trap PDUs.
<ipv4-addr >: User-defined interface IPv4 address that is used
as the source IP address in generated traps. IPv6 addresses
are not supported.
Notes When you use the snmp-server response-source and snmp-server trap-source
commands, note the following behavior:
■ The snmp-server response-source and snmp-server trap-source commands
configure the source IP address for IPv4 interfaces only.
■ You must manually configure the snmp-server response-source value if you
wish to change the default user-defined interface IP address that is used
as the source IP address in SNMP traps (RFC 1517).
■ The values configured with the snmp-server response-source and snmp-
server trap-source commands are applied globally to all interfaces that are
sending SNMP responses or SNMP trap PDUs.
■ Only the source IP address field in the IP header of the SNMP response
PDU can be changed.
■ Only the source IP address field in the IP header and the SNMPv1 Agent
Address field of the SNMP trap PDU can be changed.
To verify the configuration of the interface IP address used as the source IP
address in IP headers for SNMP replies and traps sent from the switch, enter

LLDP-MED (LLDP Media Endpoint Discovery): Provides an extension to
LLDP and is designed to support VoIP deployments.
Note LLDP-MED is an extension for LLDP, and the switch requires that LLDP be
enabled as a prerequisite to LLDP-MED operation.
An SNMP utility can progressively discover LLDP devices in a network by:
1. Reading a given device’s Neighbors table (in the Management Information
Base, or MIB) to learn about other, neighboring LLDP devices.
2. Using the information learned in step 1 to find and read the neighbor
devices’ Neighbors tables to learn about additional devices, and so on.
Also, by using show commands to access the switch’s neighbor database for
information collected by an individual switch, system administrators can learn
about other devices connected to the switch, including device type
(capability) and some configuration information. In VoIP deployments using
LLDP-MED on the switches covered in this guide, additional support unique to
VoIP applications is also available. Refer to “LLDP-MED (Media-Endpoint-
Discovery)” on page 13-53.
Terminology
Adjacent Device: Refer to “Neighbor or Neighbor Device”.
Advertisement: See LLDPDU.
Active Port: A port linked to another active device (regardless of whether
MSTP is blocking the link).
ELIN (Emergency Location Identification Number): A valid telephone
number in the North American Numbering Plan format and assigned to a
multiline telephone system operator by the appropriate authority. This

data packets even if it is not LLDP-aware.
LLDPDU (LLDP Data Unit): LLDP data packet are transmitted on active
links and include multiple TLVs containing global and per-port switch
information. In this guide, LLDPDUs are termed “advertisements” or

PSAP (Public Safety Answering Point): PSAPs are typically emergency
telephone facilities established as a first point to receive emergency (911) calls
and to dispatch emergency response services such as police, fire and
emergency medical services.
PSE (Power-Sourcing Equipment): A PSE, such as a PoE module installed

TLV (Type-Length-Value): A data unit that includes a data type field, a data
unit length field (in bytes), and a field containing the actual data the unit is
designed to carry (as an alphanumeric string, a bitmap, or a subgroup of
information). Some TLVs include subelements that occur as separate data
points in displays of information maintained by the switch for LLDP
advertisements. (That is, some TLVs include multiple data points or
subelements.)
General LLDP Operation
An LLDP packet contains data about the transmitting switch and port. The
switch advertises itself to adjacent (neighbor) devices by transmitting LLDP
data packets out all ports on which outbound LLDP is enabled, and reading
LLDP advertisements from neighbor devices on ports that are inbound LLDP-
enabled. (LLDP is a one-way protocol and does not include any
acknowledgement mechanism.) An LLDP-enabled port receiving LLDP
packets inbound from neighbor devices stores the packet data in a Neighbor
database (MIB).
LLDP-MED
This capability is an extension to LLDP and is available on the switches
covered in this guide. Refer to “LLDP-MED (Media-Endpoint-Discovery)” on
page 13-53.
Packet Boundaries in a Network Topology
■ Where multiple LLDP devices are directly connected, an outbound LLDP
packet travels only to the next LLDP device. An LLDP-capable device does
not forward LLDP packets to any other devices, regardless of whether
they are LLDP-enabled.
■ An intervening hub or repeater forwards the LLDP packets it receives in
the same manner as any other multicast packets it receives. Thus, two
LLDP switches joined by a hub or repeater handle LLDP traffic in the same
way that they would if directly connected.
■ Any intervening 802.1D device or Layer-3 device that is either LLDP-
unaware or has disabled LLDP operation drops the packet.

Configuration Options
Enable or Disable LLDP on the Switch. In the default configuration,
LLDP is globally enabled on the switch. To prevent transmission or receipt of
LLDP traffic, you can disable LLDP operation (page 13-38)
Enable or Disable LLDP-MED. In the default configuration for the
switches covered in this guide, LLDP-MED is enabled by default. (Requires that
LLDP is also enabled.) For more information, refer to “LLDP-MED (Media-
Endpoint-Discovery)” on page 13-53.
Change the Frequency of LLDP Packet Transmission to Neighbor
Devices. On a global basis, you can increase or decrease the frequency of
outbound LLDP advertisements (page 13-38).
Change the Time-To-Live for LLDP Packets Sent to Neighbors. On a
global basis, you can increase or decrease the time that the information in an
LLDP packet outbound from the switch will be maintained in a neighbor LLDP
device (page 13-38).
Transmit and Receive Mode. With LLDP enabled, the switch periodically
transmits an LLDP advertisement (packet) out each active port enabled for
outbound LLDP transmissions, and receives LLDP advertisements on each
active port enabled to receive LLDP traffic (page 13-49). Per-Port
configuration options include four modes:
■ Transmit and Receive (tx_rx): This is the default setting on all ports. It
enables a given port to both transmit and receive LLDP packets, and to
store the data from received (inbound) LLDP packets in the switch’s MIB.
■ Transmit only (txonly): This setting enables a port to transmit LLDP
packets that can be read by LLDP neighbors. However, the port drops
inbound LLDP packets from LLDP neighbors without reading them. This
prevents the switch from learning about LLDP neighbors on that port.
■ Receive only (rxonly): This setting enables a port to receive and read LLDP
packets from LLDP neighbors, and to store the packet data in the switch’s
MIB. However, the port does not transmit outbound LLDP packets. This
prevents LLDP neighbors from learning about the switch through that
port.
■ Disable (disable): This setting disables LLDP packet transmissions and
reception on a port. In this state, the switch does not use the port for either
learning about LLDP neighbors or informing LLDP neighbors of its pres-
ence.

■ RFC 2737 (Entity MIB)

LLDP Operating Rules
(For additional information specific to LLDP-MED operation, refer to “LLDP-
MED (Media-Endpoint-Discovery)” on page 13-53.)
Port Trunking. LLDP manages trunked ports individually. That is, trunked
ports are configured individually for LLDP operation, in the same manner as
non-trunked ports. Also, LLDP sends separate advertisements on each port in
a trunk, and not on a per-trunk basis. Similarly, LLDP data received through
trunked ports is stored individually, per-port.
IP Address Advertisements. In the default operation, if a port belongs to
only one static VLAN, then the port advertises the lowest-order IP address
configured on that VLAN. If a port belongs to multiple VLANs, then the port
advertises the lowest-order IP address configured on the VLAN with the
lowest VID. If the qualifying VLAN does not have an IP address, the port
advertises 127.0.0.1 as its IP address. For example, if the port is a member of
the default VLAN (VID = 1), and there is an IP address configured for the
default VLAN, then the port advertises this IP address. In the default operation,
the IP address that LLDP uses can be an address acquired by DHCP or Bootp.
You can override the default operation by configuring the port to advertise
any IP address that is manually configured on the switch, even if the port does
not belong to the VLAN configured with the selected IP address (page 13-50).
(Note that LLDP cannot be configured through the CLI to advertise an
addresses acquired through DHCP or Bootp. However, as mentioned above,
in the default LLDP configuration, if the lowest-order IP address on the VLAN
with the lowest VID for a given port is a DHCP or Bootp address, then the
switch includes this address in its LLDP advertisements unless another
address is configured for advertisements on that port.) Also, although LLDP
allows configuring multiple remote management addresses on a port, only the
lowest-order address configured on the port will be included in outbound
13-41
Configuring for Network Management Applications

advertisements. Attempting to use the CLI to configure LLDP with an IP
address that is either not configured on a VLAN, or has been acquired by DHCP
or Bootp results in the following error message.
xxx.xxx.xxx.xxx: This IP address is not configured or is
a DHCP address.
Spanning-Tree Blocking. Spanning tree does not prevent LLDP packet
transmission or receipt on STP-blocked links.
802.1X Blocking. Ports blocked by 802.1X operation do not allow
transmission or receipt of LLDP packets.
Configuring LLDP Operation
In the default configuration, LLDP is enabled and in both transmit and receive
mode on all active ports. The LLDP configuration includes global settings that
apply to all active ports on the switch, and per-port settings that affect only

Configuring Global LLDP Packet Controls
The commands in this section configure the aspects of LLDP operation that
apply the same to all ports in the switch.
13-44
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Enabling or Disabling LLDP Operation on the Switch. Enabling LLDP
operation (the default) causes the switch to:
■ Use active, LLDP-enabled ports to transmit LLDP packets describing itself
to neighbor devices.
■ Add entries to its neighbors table based on data read from incoming LLDP
advertisements.
Syntax [ no ] lldp run
Enables or disables LLDP operation on the switch. The no form
of the command, regardless of individual LLDP port
configurations, prevents the switch from transmitting
outbound LLDP advertisements, and causes the switch to drop
all LLDP advertisements received from other devices. The
switch preserves the current LLDP configuration when LLDP
is disabled. After LLDP is disabled, the information in the
LLDP neighbors database remains until it times-out. (Default:
Enabled)
For example, to disable LLDP on the switch:
ProCurve(config)# no lldp run
Changing the Packet Transmission Interval. This interval controls how
often active ports retransmit advertisements to their neighbors.
Syntax lldp refresh-interval < 5 - 32768 >
Changes the interval between consecutive transmissions of
LLDP advertisements on any given port. (Default: 30 seconds)
Note: The refresh-interval must be greater than or equal to
(4 x delay-interval). (The default delay-interval is 2). For
example, with the default delay-interval, the lowest refresh-
interval you can use is 8 seconds (4 x 2 = 8). Thus, if you want
a refresh-interval of 5 seconds, you must first change the delay
interval to 1 (that is, 4 x 1 < 5). If you want to change the delay-
interval, use the setmib command.
13-45
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Changing the Time-to-Live for Transmitted Advertisements. The
Time-to-Live value (in seconds) for all LLDP advertisements transmitted from
a switch is controlled by the switch that generates the advertisement, and
determines how long an LLDP neighbor retains the advertised data before
discarding it. The Time-to-Live value is the result of multiplying the refresh-
interval by the holdtime-multiplier described below.
Syntax lldp holdtime-multiplier < 2 - 10 >
Changes the multiplier an LLDP switch uses to calculate the
Time-to-Live for the LLDP advertisements it generates and
transmits to LLDP neighbors. When the Time-to-Live for a
given advertisement expires the advertised data is deleted from
the neighbor switch’s MIB. (Default: 4; Range: 2 - 10)
For example, if the refresh-interval on the switch is 15 seconds and the
holdtime-multiplier is at the default, the Time-to-Live for advertisements
transmitted from the switch is 60 seconds (4 x 15). To reduce the Time-to-Live,
you could lower the holdtime-interval to 2, which would result in a Time-to-
Live of 30 seconds.
ProCurve(config)# lldp holdtime-multiplier 2
Changing the Delay Interval Between Advertisements Generated by
Value or Status Changes to the LLDP MIB. The switch uses a delay-
interval setting to delay transmitting successive advertisements resulting
from these LLDP MIB changes. If a switch is subject to frequent changes to
its LLDP MIB, lengthening this interval can reduce the frequency of successive
advertisements. The delay-interval can be changed using either an SNMP
network management application or the CLI setmib command.
13-46
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Syntax setmib lldpTxDelay.0 -i < 1 - 8192 >
Uses setmib to change the minimum time (delay-interval)
any LLDP port will delay advertising successive LLDP
advertisements due to a change in LLDP MIB content.
(Default: 2; Range: 1 - 8192)
Note: The LLDP refresh-interval (transmit interval) must be
greater than or equal to (4 x delay-interval). The switch does
not allow increasing the delay interval to a value that
conflicts with this relationship. That is, the switch displays
Inconsistent value if (4 x delay-interval) exceeds the current
transmit interval, and the command fails. Depending on the
current refresh-interval setting, it may be necessary to
increase the refresh-interval before using this command to
increase the delay-interval.
For example, to change the delay-interval from 2 seconds to 8 seconds when
the refresh-interval is at the default 30 seconds, you must first set the refresh-
interval to a minimum of 32 seconds (32 = 4 x 8).
Figure 13-16. Example of Changing the Transmit-Delay Interval
Attempt to change the transmit-delay
interval shows that the refresh-
interval is less than (4 x delay-interval).
Changes the refresh-interval to 32; that is:
32 = 4 x (desired transmit-delay interval)
Successfully changes the transmit-
delay interval to 8.
Changing the Reinitialization Delay Interval. In the default
configuration, a port receiving a disable command followed immediately by a
txonly, rxonly, or tx_rx command delays reinitializing for two seconds, during
which time LLDP operation remains disabled. If an active port is subjected to
frequent toggling between the LLDP disabled and enabled states, LLDP
advertisements are more frequently transmitted to the neighbor device. Also,
the neighbor table in the adjacent device will change more frequently, as it
deletes, then replaces LLDP data for the affected port which, in turn, generates
SNMP traps (if trap receivers and SNMP notification are configured). All of
this can unnecessarily increase network traffic. Extending the reinitialization-
13-47
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
delay interval delays the port’s ability to reinitialize and generate LLDP traffic
following an LLDP disable/enable cycle.
Syntax setmib lldpReinitDelay.0 -i < 1 - 10 >
Uses setmib to change the minimum time (reinitialization
delay interval) an LLDP port will wait before reinitializing
after receiving an LLDP disable command followed closely by
a txonly or tx_rx command. The delay interval commences
with execution of the lldp admin-status < port-list > disable
command. (Default: 2 seconds; Range: 1 - 10 seconds)
For example, the following command changes the reinitialization delay
interval to five seconds:
ProCurve(config)# setmib lldpreinitdelay.0 -i 5
Configuring SNMP Notification Support
You can enable SNMP trap notification of LLDP data changes detected on
advertisements received from neighbor devices, and control the interval
between successive notifications of data changes on the same neighbor.
Enabling LLDP Data Change Notification for SNMP Trap Receivers.
Syntax [ no ] lldp enable-notification < port-list >
Enables or disables each port in < port-list > for sending
notification to configured SNMP trap receiver(s) if an LLDP
data change is detected in an advertisement received on the
port from an LLDP neighbor. (Default: Disabled)
For information on configuring trap receivers in the switch,
refer to “SNMP Notifications” on page 13-17.
For example, this command enables SNMP notification on ports 1 - 5:
ProCurve(config)# lldp enable-notification 1-5
13-48
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Changing the Minimum Interval for Successive Data Change
Notifications for the Same Neighbor.
If LLDP trap notification is enabled on a port, a rapid succession of changes
in LLDP information received in advertisements from one or more neighbors
can generate a high number of traps. To reduce this effect, you can globally
change the interval between successive notifications of neighbor data change.
Syntax setmib lldpnotificationinterval.0 -i < 1 - 3600 >
Globally changes the interval between successive traps
generated by the switch. If multiple traps are generated in the
specified interval, only the first trap will be sent. The
remaining traps will be suppressed. (A network management
application can periodically check the switch MIB to detect any
missed change notification traps. Refer to IEEE P802.1AB or
later for more information.) (Default: 5 seconds)
For example, the following command limits change notification traps from a
particular switch to one per minute.
ProCurve(config)# setmib lldpnotificationinterval.0 -i 60
lldpNotificationInterval.0 = 60
Configuring Per-Port Transmit and Receive Modes
These commands control advertisement traffic inbound and outbound on
active ports.
Syntax lldp admin-status < port-list > < txonly | rxonly | tx_rx | disable >
With LLDP enabled on the switch in the default configuration,
each port is configured to transmit and receive LLDP packets.
These options enable you to control which ports participate in
LLDP traffic and whether the participating ports allow LLDP
traffic in only one direction or in both directions.
txonly: Configures the specified port(s) to transmit LLDP pack-
ets, but block inbound LLDP packets from neighbor devices.
rxonly: Configures the specified port(s) to receive LLDP packets
from neighbors, but block outbound packets to neighbors.
tx_rx: Configures the specified port(s) to both transmit and
receive LLDP packets. (This is the default setting.)
disable: Disables LLDP packet transmit and receive on the
specified port(s).
13-49
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Configuring Basic LLDP Per-Port Advertisement Content
In the default LLDP configuration, outbound advertisements from each port
on the switch include both mandatory and optional data.
Mandatory Data. An active LLDP port on the switch always includes the
mandatory data in its outbound advertisements. LLDP collects the mandatory
data, and, except for the Remote Management Address, you cannot use LLDP
commands to configure the actual data.
■ Chassis Type (TLV subelement)
■ Chassis ID (TLV)
■ Port Type (TLV subelement)
■ Port ID (TLV)
■ Remote Management Address (TLV; actual IP address is a subelement that
can be a default address or a configured address)
Configuring a Remote Management Address for Outbound LLDP
Advertisements. This is an optional command you can use to include a
specific IP address in the outbound LLDP advertisements for specific ports.
Syntax [ no ] lldp config < port-list > ipAddrEnable < ip-address >
Replaces the default IP address for the port with an IP
address you specify. This can be any IP address configured
in a static VLAN on the switch, even if the port does not
belong to the VLAN configured with the selected IP address.
The no form of the command deletes the specified IP
address. If there are no IP addresses configured as
management addresses, then the IP address selection
method returns to the default operation. (Default: The port
advertises the IP address of the lowest-numbered VLAN
(VID) to which it belongs. If there is no IP address
configured on the VLAN(s) to which the port belongs, and
the port is not configured to advertise an IP address from
any other (static) VLAN on the switch, then the port
advertises an address of 127.0.0.1.)
Note: This command does not accept either IP addresses
acquired through DHCP or Bootp, or IP addresses that are
not configured in a static VLAN on the switch

Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
For example, if port 3 belongs to a subnetted VLAN that includes an IP address
of 10.10.10.100 and you wanted port 3 to use this secondary address in LLDP
advertisements, you would need to execute the following command:
ProCurve(config)# lldp config 3 ipAddrEnable 10.10.10.100
Optional Data. You can configure an individual port or group of ports to
exclude one or more of these data types from outbound LLDP advertisements.
Note that optional data types, when enabled, are populated with data internal
to the switch; that is, you cannot use LLDP commands to configure their actual
content.
■ port description (TLV)
■ system name (TLV)
■ system description (TLV)

For example, if you wanted to exclude the system name TLV from the
outbound LLDP advertisements for all ports on a switch, you would use this
command:
ProCurve(config)# no lldp config 1-24 basicTlvEnable

If you later decided to reinstate the system name TLV on ports 1-5, you would
use this command:
ProCurve(config)# lldp config 1-5 basicTlvEnable
system_name
Configuring Support for Port Speed and Duplex
Advertisements
This feature is optional for LLDP operation, but is required for LLDP-MED
operation.
Port speed and duplex advertisements are supported on the switches covered
in this guide to inform an LLDP endpoint and the switch port of each other’s
port speed and duplex configuration and capabilities. Configuration
mismatches between a switch port and an LLDP endpoint can result in
excessive collisions and voice quality degradation. LLDP enables discovery of
such mismatches by supporting SNMP access to the switch MIB for comparing
the current switch port and endpoint settings. (Changing a current device
configuration to eliminate a mismatch requires intervention by the system
operator.)
13-52
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Syntax: [ no ] lldp config < port-list > dot3TlvEnable macphy_config
For outbound advertisements, this TLV includes the
(local) switch port’s current speed and duplex settings, the
range of speed and duplex settings the port supports, and
the method required for reconfiguring the speed and
duplex settings on the device (auto-negotiation during
link initialization, or manual configuration).
Using SNMP to compare local and remote information can
help in locating configuration mismatches.
(Default: Enabled)
Note: For LLDP operation, this TLV is optional. For
LLDP-MED operation, this TLV is mandatory.
As mentioned above, an SNMP network management application can be used
to compare the port speed and duplex data configured in the switch and
advertised by the LLDP endpoint. You can also use the CLI to display this
information. For more on using the CLI to display port speed and duplex
information, refer to “Displaying the Current Port Speed and Duplex
Configuration on a Switch Port” on page 13-69.
LLDP-MED (Media-Endpoint-Discovery)
LLDP-MED (ANSI/TIA-1057/D6) extends the LLDP (IEEE 802.1AB) industry
standard to support advanced features on the network edge for Voice Over IP
(VoIP) endpoint devices with specialized capabilities and LLDP-MED
standards-based functionality. LLDP-MED in the switches uses the standard
LLDP commands described earlier in this section, with some extensions, and
also introduces new commands unique to LLDP-MED operation. The show
commands described elsewhere in this section are applicable to both LLDP
and LLDP-MED operation. LLDP-MED benefits include:
■ plug-and-play provisioning for MED-capable, VoIP endpoint devices
■ simplified, vendor-independent management enabling different IP
telephony systems to interoperate on one network
■ automatic deployment of convergence network policies (voice
VLANs, Layer 2/CoS priority, and Layer 3/QoS priority)
■ configurable endpoint location data to support the Emergency Call
Service (ECS) (such as Enhanced 911 service, 999, 112)
■ detailed VoIP endpoint data inventory readable via SNMP from the
switch

LLDP (Link-Layer Discovery Protocol)
■ able to use the following network policy elements configured on the

• voice VLAN ID
• 802.1p (Layer 2) QoS
• Diffserv codepoint (DSCP) (Layer 3) QoS
■ discover and advertise device location data learned from the switch
■ support emergency call service (ECS—such as E911, 999, and 112)
■ advertise device information for the device data inventory collected
by the switch, including:
• hardware revision • serial number • asset ID
• firmware revision • manufacturer name
• software revision • model name
■ provide information on network connectivity capabilities (for
example, a multi-port VoIP phone with Layer 2 switch capability)
■ support the fast start capability
Note LLDP-MED on the switches covered in this guide is intended for use with VoIP
endpoints, and is not designed to support links between network
infrastructure devices, such as switch-to-switch or switch-to-router links.
LLDP-MED Endpoint Device Classes. LLDP-MED endpoint devices are,
by definition, located at the network edge and communicate using the LLDP-
MED framework. Any LLDP-MED endpoint device belongs to one of the
following three classes:
■ Class 1 (Generic Endpoint Devices): These devices offer the basic
LLDP discovery services, network policy advertisement (VLAN ID,
Layer 2/802.1p priority, and Layer 3/DSCP priority), and PoE manage-
ment. This class includes such devices as IP call controllers and
communication-related servers.
■ Class 2 (Media Endpoint Devices): These devices offer all Class 1
features plus media streaming capability, and include such devices as
voice/media gateways, conference bridges, and media servers.
13-55
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
■ Class 3 (Communication Devices): These devices are typically IP
phones or end-user devices that otherwise support IP media and offer
all Class 1 and Class 2 features, plus location identification and
emergency 911 capability, Layer 2 switch support, and device infor-
mation management.
LLDP-MED Operational Support. The switches covered in this guide offer
two configurable TLVs supporting MED-specific capabilities:
■ medTlvEnable (for per-port enabling or disabling of LLDP-MED opera-
tion)
■ medPortLocation (for configuring per-port location or emergency call
data)
Note LLDP-MED operation also requires the port speed and duplex TLV
(dot3TlvEnable; page 13-53), which is enabled in the default configuration.
LLDP-MED Topology Change Notification
This optional feature provides information an SNMP application can use to
track LLDP-MED connects and disconnects.
13-56
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Syntax: lldp top-change-notify < port-list >
Topology change notification, when enabled on an LLDP
port, causes the switch to send an SNMP trap if it detects
LLDP-MED endpoint connection or disconnection activity
on the port, or an age-out of the LLDP-MED neighbor on the
port. The trap includes the following information:
■ the port number (internal) on which the activity was
detected (For more in internal port numbers, refer to
“Determining the Switch Port Number Included in
Topology Change Notification Traps” on page 13-75.)
■ the LLDP-MED class of the device detected on the port
(“LLDP-MED Endpoint Device Classes” on page 13-55.)
The show running command shows whether the topology
change notification feature is enabled or disabled. For
example, if ports A1-A10 have topology change notification
enabled, the following entry appears in the show running
output:
lldp top-change-notify A1-A10
(Default: Disabled)
Note: To send traps, this feature requires access to at least
one SNMP server. For information on configuring traps,
refer to “SNMP Notifications” on page 13-17.
Also, if a detected LLDP-MED neighbor begins sending
advertisements without LLDP-MED TLVs, the switch sends
a top-change-notify trap.
Note Topology change notifications provide one method for monitoring system
activity. However, because SNMP normally employs UDP, which does not
guarantee datagram delivery, topology change notification should not be
relied upon as the sole method for monitoring critical endpoint device
connectivity.
13-57
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
LLDP-MED Fast Start Control
Syntax: lldp fast-start-count < 1 - 10 >
An LLDP-MED device connecting to a switch port may use
the data contained in the MED TLVs from the switch to
configure itself. However, the lldp refresh-interval setting
(default: 30 seconds) for transmitting advertisements can
cause an unacceptable delay in MED device configuration.
To support rapid LLDP-MED device configuration, the lldp
fast-start-count command temporarily overrides the refresh-
interval setting for the fast-start-count advertisement interval.
This results in the port initially advertising LLDP-MED at
a faster rate for a limited time. Thus, when the switch detects
a new LLDP-MED device on a port, it transmits one LLDP-
MED advertisement per second out the port for the duration
of the fast-start-count interval. In most cases, the default
setting should provide an adequate fast-start-count interval.
(Range: 1 - 10 seconds; Default: 5 seconds)
Note: This global command applies only to ports on which
a new LLDP-MED device is detected. It does not override the
refresh-interval setting on ports where non-MED devices are
detected.
Advertising Device Capability, Network Policy, PoE Status
and Location Data
The medTlvEnable option on the switch is enabled in the default configuration
and supports the following LLDP-MED TLVs:
■ LLDP-MED capabilities: This TLV enables the switch to determine:
• whether a connected endpoint device supports LLDP-MED
• which specific LLDP-MED TLVs the endpoint supports
• the device class (1, 2, or 3) for the connected endpoint
This TLV also enables an LLDP-MED endpoint to discover what LLDP-
MED TLVs the switch port currently supports.
■ network policy operating on the port to which the endpoint is connected
(VLAN, Layer 2 QoS, Layer 3 QoS)
■ PoE (MED Power-over-Ethernet)
■ physical location data — page 13-62

Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
Note LLDP-MED operation requires the macphy_config TLV subelement—enabled
by default—that is optional for IEEE 802.1AB LLDP operation. Refer to the
dot3TlvEnable macphy_config command on page 13-53.
Network Policy Advertisements. Network policy advertisements are
intended for real-time voice and video applications, and include these TLV
subelements:
■ Layer 2 (802.1p) QoS
■ Layer 3 DSCP (diffserv code point) QoS
■ Voice VLAN ID (VID)
VLAN Operating Rules. These rules affect advertisements of VLANs in
network policy TLVs:
■ The VLAN ID TLV subelement applies only to a VLAN configured for voice
operation (vlan < vid > voice).
■ If there are multiple voice VLANs configured on a port, LLDP-MED
advertises the voice VLAN having the lowest VID.
■ The voice VLAN port membership configured on the switch can be tagged
or untagged. However, if the LLDP-MED endpoint expects a tagged mem-
bership when the switch port is configured for untagged, or the reverse,
then a configuration mismatch results. (Typically, the endpoint expects
the switch port to have a tagged voice VLAN membership.)
■ If a given port does not belong to a voice VLAN, then the switch does not
advertise the VLAN ID TLV through this port.
Policy Elements. These policy elements may be statically configured on the
switch or dynamically imposed during an authenticated session on the switch
using a RADIUS server and 802.1X or MAC authentication. (Web
authentication does not apply to VoIP telephones and other
telecommunications devices that are not capable of accessing the switch
through a Web browser.) The QoS and voice VLAN policy elements can be
statically configured with the following CLI commands:
vlan < vid > voice
vlan < vid > < tagged | untagged > < port-list >
int < port-list > qos priority < 0 - 7 >
vlan < vid > qos dscp < codepoint >

network-policy
This TLV enables the switch port to advertise its
configured network policies (voice VLAN, Layer 2 QoS,
Layer 3 QoS), and allows LLDP-MED endpoint devices to
auto-configure the voice network policy advertised by the
switch. This also enables the use of SNMP applications to
troubleshoot statically configured endpoint network
policy mismatches.
(Default: Enabled)
Notes: Network policy is only advertised for ports that are
configured as members of the voice VLAN. If the port
belongs to more than one voice VLAN, then the voice
VLAN with the lowest-numbered VID is selected as the
VLAN for voice traffic. Also, this TLV cannot be enabled
unless the capability TLV is already enabled.
For more information, refer to “Network Policy
Advertisements” on page 13-59
location_id
This TLV enables the switch port to advertise its
configured location data (if any). For more on
configuring location data, refer to “Configuring Location
Data for LLDP-MED Devices”.
(Default: Enabled)
Note: When disabled, this TLV cannot be enabled unless
the capability TLV is already enabled.
poe
This TLV enables the switch port to advertise its current
PoE (Power over Ethernet) state and to read the PoE
requirements advertised by the LLDP-MED endpoint
device connected to the port.
(Default: Enabled)
Note: When disabled, this TLV cannot be enabled unless
the capability TLV is already enabled.

PoE Advertisements. These advertisements inform an LLDP-MED
endpoint of the power (PoE) configuration on switch ports. Similar
advertisements from an LLDP-MED endpoint inform the switch of the
endpoint’s power needs and provide information that can be used to identify
power priority mismatches.
Power-over-Ethernet TLVs include the following power data:
■ power type: indicates whether the device is a power-sourcing entity
(PSE) or a powered device (PD). A MED-capable VoIP telephone is a PD.
■ power source: indicates the source of power in use by the device. Power
sources for powered devices (PDs) include PSE, local (internal), and PSE/
local. The switches covered in this guide advertise Unknown.
■ power priority: indicates the power priority configured on the switch
(PSE) port or the power priority configured on the MED-capable end-
point.
■ power value: indicates the total power in watts that a switch port (PSE)
can deliver at a particular time, or the total power in watts that the MED
endpoint (PD) requires to operate.
To display the current power data for an LLDP-MED device connected to a
port, use the following command:
show lldp info remote-device < port-list >
For more on this command, refer to page 13-70.
To display the current PoE configuration on the switch, use the following
commands:
show power brief < port-list >

For more on PoE configuration and operation, refer to Chapter 11, “Power
Over Ethernet (PoE) Operation”.
Configuring Location Data for LLDP-MED Devices
You can configure a switch port to advertise location data for the switch itself,
the physical wall-jack location of the endpoint (recommended), or the
location of a DHCP server supporting the switch and/or endpoint. You also
have the option of configuring these different address types:
■ civic address: physical address data such as city, street number, and
building information
13-62
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
■ ELIN (Emergency Location Identification Number): an emergency
number typically assigned to MLTS (Multiline Telephone System Opera-
tors) in North America
■ coordinate-based location: attitude, longitude, and altitude informa-
tion (Requires configuration via an SNMP application.)
Syntax: [ no ] lldp config < port-list > medPortLocation < Address-Type >
Configures location or emergency call data the switch advertises
per port in the location_id TLV. This TLV is for use by LLDP-
MED endpoints employing location-based applications.
Note: The switch allows one medPortLocation entry per
port (without regard to type). Configuring a new
medPortLocation entry of any type on a port replaces
any previously configured entry on that port.
civic-addr < COUNTRY-STR > < WHAT > < CA-TYPE > < CA-VALUE > . . .
[< CA-TYPE > < CA-VALUE >] . . . [< CA-TYPE > < CA-VALUE >]
This command enables configuration of a physical
address on a switch port, and allows up to 75 characters
of address information.
COUNTRY-STR: A two-character country code, as defined by
ISO 3166. Some examples include FR (France), DE
(Germany), and IN (India). This field is required in a
civic-addr command. (For a complete list of country codes,
visit www.iso.org on the world wide web.)
WHAT: A single-digit number specifying the type of device
to which the location data applies:
0: Location of DHCP server
1: Location of switch
2: Location of LLDP-MED endpoint (recommended
application)
This field is required in a civic-addr command.

Type/Value Pairs (CA-TYPE and CA-VALUE): This is a
series of data pairs, each composed of a location data
“type” specifier and the corresponding location data
for that type. That is, the first value in a pair is
expected to be the civic address “type” number (CA-
TYPE), and the second value in a pair is expected to
be the corresponding civic address data (CA-VALUE).
For example, if the CA-TYPE for “city name” is “3”, then
the type/value pair to define the city of Paris is “3
Paris”. Multiple type/value pairs can be entered in any
order, although it is recommended that multiple
pairs be entered in ascending order of the CA-
TYPE.When an emergency call is placed from a
properly configured class 3 endpoint device to an
appropriate PSAP, the country code, device type, and
type/value pairs configured on the switch port are
included in the transmission. The “type” specifiers
are used by the PSAP to identify and organize the
location data components in an understandable
format for response personnel to interpret. A civic-
addr command requires a minimum of one type/
value pair, but typically includes multiple type/value
pairs as needed to configure a complete set of data
describing a given location. CA-TYPE: This is the first
entry in a type/value pair, and is a number defining
the type of data contained in the second entry in the
type/value pair (CA-VALUE). Some examples of CA-TYPE
specifiers include:
•3 = city
• 6 = street (name)
• 25 = building name
(Range: 0 - 255)
For a sample listing of CA-TYPE specifiers, refer to table
13-4 on page 13-66.
CA-VALUE: This is the second entry in a type/value
pair, and is an alphanumeric string containing
the location information corresponding to the
immediately preceding CA-TYPE entry. Strings
are delimited by either blank spaces, single
quotes (‘ ... ‘), or double quotes (“ ... “). Each string
should represent a specific data type in a set of
unique type/value pairs comprising the
description of a location, and each string must
be preceded by a CA-TYPE number identifying the
type of data in the string.

Note: A switch port allows one instance of any given CA-
TYPE. For example, if a type/value pair of 6 Atlantic (to
specify “Atlantic” as a street name) is configured on port
A5 and later another type/value pair of 6 Pacific is
configured on the same port, then Pacific replaces Atlantic
in the civic address location configured for port A5.
elin-addr < emergency-number >
This feature is intended for use in Emergency Call Service

telephones connected to a switch covered in this guide in
a multiline telephone system (MLTS) infrastructure. An
ELIN (Emergency Location Identification Number) is a
valid North American Numbering Plan (NANP) format
telephone number assigned to MLTS operators in North
America by the appropriate authority. The ELIN is used
to route emergency (E911) calls to a Public Safety
Answering Point (PSAP).

from other LLDP devices.
Syntax show lldp info remote-device [ port-list ]
Without the [ port-list ] option, this command provides a global
list of the individual devices it has detected by reading LLDP
advertisements. Discovered devices are listed by the inbound
port on which they were discovered. Multiple devices listed for
a single port indicates that such devices are connected to the
switch through a hub.
Discovering the same device on multiple ports indicates that
the remote device may be connected to the switch in one of the
following ways:
– Through different VLANS using separate links. (This
applies to switches that use the same MAC address for all
configured VLANs.)
– Through different links in the same trunk.
– Through different links using the same VLAN. (In this
case, spanning-tree should be invoked to prevent a net-
work topology loop. Note that LLDP packets travel on links
that spanning-tree blocks for other traffic types.)

the LLDP data that the switch has detected in advertisements
received on the specified ports.

Displaying LLDP Statistics
LLDP statistics are available on both a global and a per-port levels. Rebooting
the switch resets the LLDP statistics counters to zero. Disabling the transmit
and/or receive capability on a port “freezes” the related port counters at their
current values.
Syntax show lldp stats [ port-list ]
The global LLDP statistics command displays an overview of
neighbor detection activity on the switch, plus data on the
number of frames sent, received, and discarded per-port. The
per-port LLDP statistics command enhances the list of per-port
statistics provided by the global statistics command with some
additional per-port LLDP statistics.
Global LLDP Counters:
Neighbor Entries List Last Updated: Shows the elapsed time since
a neighbor was last added or deleted.
New Neighbor Entries Count: Shows the total of new LLDP
neighbors detected since the last switch reboot. Disconnecting,
then reconnecting a neighbor increments this counter.
Neighbor Entries Deleted Count: Shows the number of neighbor
deletions from the MIB for AgeOut Count and forced drops for
all ports. For example, if the admin status for port on a
neighbor device changes from tx_rx or txonly to disabled or
rxonly, then the neighbor device sends a “shutdown” packet out
the port and ceases transmitting LLDP frames out that port.
The device receiving the shutdown packet deletes all
information about the neighbor received on the applicable
inbound port and increments the counter.
Neighbor Entries Dropped Count: Shows the number of valid LLDP
neighbors the switch detected, but could not add. This can
occur, for example, when a new neighbor is detected when the
switch is already supporting the maximum number of
neighbors. Refer to “Neighbor Maximum” on page 13-74.
Neighbor Entries AgeOut Count: Shows the number of LLDP
neighbors dropped on all ports due to Time-to-Live expiring.

Per-Port LLDP Counters:
NumFramesRecvd: Shows the total number of valid, inbound
LLDP advertisements received from any neighbor(s) on < port-
list >. Where multiple neighbors are connected to a port through
a hub, this value is the total number of LLDP advertisements
received from all sources.
NumFramesSent: Shows the total number of LLDP
advertisements sent from < port-list >.
NumFramesDiscarded: Shows the total number of inbound LLDP
advertisements discarded by < port-list >. This can occur, for
example, when a new neighbor is detected on the port, but the
switch is already supporting the maximum number of
neighbors. Refer to “Neighbor Maximum” on page 13-74. This
can also be an indication of advertisement formatting
problems in the neighbor device.
Frames Invalid: Shows the total number of invalid LLDP
advertisements received on the port. An invalid advertisement
can be caused by header formatting problems in the neighbor
device.
TLVs Unrecognized: Shows the total number of LLDP TLVs
received on a port with a type value in the reserved range. This
could be caused by a basic management TLV from a later LLDP
version than the one currently running on the switch.
TLVs Discarded: Shows the total number of LLDP TLVs discarded
for any reason. In this case, the advertisement carrying the
TLV may be accepted, but the individual TLV was not usable.

Neighbor Maximum. The neighbors table in the switch supports as many
neighbors as there are ports on the switch. The switch can support multiple

802.1Q VLAN Information. LLDP packets do not include 802.1Q header
information, and are always handled as untagged packets.
Effect of 802.1X Operation. If 802.1X port security is enabled on a port
and a connected device is not authorized, LLDP packets are not transmitted
or received on that port. Any neighbor data stored in the neighbor MIB for that
port prior to the unauthorized device connection remains in the MIB until it
ages out. If an unauthorized device later becomes authorized, LLDP transmit
and receive operation resumes.
Neighbor Data Can Remain in the Neighbor Database After the
Neighbor Is Disconnected. After disconnecting a neighbor LLDP device
from the switch, the neighbor can continue to appear in the switch’s neighbor
database for an extended period if the neighbor’s holdtime-multiplier is high;
especially if the refresh-interval is large. Refer to “Changing the Time-to-Live
for Transmitted Advertisements” on page 13-46.
Mandatory TLVs. All mandatory TLVs required for LLDP operation are also
mandatory for LLDP-MED operation.
Determining the Switch Port Number Included in Topology Change
Notification Traps. Enabling topology change notification on a switch port
and then connecting or disconnecting an LLDP-MED endpoint on that port
causes the switch to send an SNMP trap to notify the designated management
station(s). The port number included in the trap corresponds to the internal
number the switch maintains for the designated port, and not the port’s
external (slot/number) identity. To match the port’s external slot/number to
the internal port number appearing in an SNMP trap, use the walkmib ifDescr

LLDP and CDP Data Management
This section describes points to note regarding LLDP (Link-Layer Discovery
Protocol) and CDP (Cisco Discovery Protocol) data received by the switch
from other devices. LLDP operation includes both transmitting LLDP packets
to neighbor devices and reading LLDP packets received from neighbor
devices. CDP operation is limited to reading incoming CDP packets from
neighbor devices. (ProCurve switches do not generate CDP packets.)
LLDP and CDP Neighbor Data
With both LLDP and (read-only) CDP enabled on a switch port, the port can
read both LLDP and CDP advertisements, and stores the data from both types
of advertisements in its neighbor database. (The switch only stores CDP data
that has a corresponding field in the LLDP neighbor database.) The neighbor
database itself can be read by either LLDP or CDP methods or by using the
show lldp commands. Take note of the following rules and conditions:
13-76
Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
■ If the switch receives both LLDP and CDP advertisements on the same
port from the same neighbor the switch stores this information as two
separate entries if the advertisements have differences chassis ID and port
ID information.
■ If the chassis and port ID information are the same, the switch stores this
information as a single entry. That is, LLDP data overwrites the corre-
sponding CDP data in the neighbor database if the chassis and port ID
information in the LLDP and CDP advertisements received from the same
device is the same.
■ Data read from a CDP packet does not support some LLDP fields, such as
“System Descr”, “SystemCapSupported”, and “ChassisType”. For such
fields, LLDP assigns relevant default values. Also:
• The LLDP “System Descr” field maps to CDP’s “Version” and “Plat-
form” fields.
• The switch assigns “ChassisType” and “PortType” fields as “local” for
both the LLDP and the CDP advertisements it receives.
• Both LLDP and CDP support the “System Capability” TLV. However,
LLDP differentiates between what a device is capable of supporting
and what it is actually supporting, and separates the two types of
information into subelements of the System Capability TLV. CDP has
only a single field for this data. Thus, when CDP System Capability
data is mapped to LLDP, the same value appears in both LLDP System
Capability fields.
• System Name and Port Descr are not communicated by CDP, and thus
are not included in the switch’s Neighbors database.
Note Because ProCurve switches do not generate CDP packets, they are not
represented in the CDP data collected by any neighbor devices running CDP.
A switch with CDP disabled forwards the CDP packets it receives from other
devices, but does not store the CDP information from these packets in its own
MIB.
LLDP data transmission/collection and CDP data collection are both enabled
in the switch’s default configuration. In this state, an SNMP network
management application designed to discover devices running either CDP or
LLDP can retrieve neighbor information from the switch regardless of whether
LLDP or CDP is used to collect the device-specific information.

1Both CDP data collection and LLDP transmit/receive are enabled in the default configuration.
If a switch receives CDP packets and LLDP packets from the same neighbor device on the
same port, it stores and displays the two types of information separately if the chassis and
port ID information in the two types of advertisements is different. In this case, if you want
to use only one type of data from a neighbor sending both types, disable the unwanted
protocol on either the neighbor device or on the switch. However, if the chassis and port ID
information in the two types of advertisements is the same, the LLDP information overwrites
the CDP data for the same neighbor device on the same port.
CDP Operation and Commands
By default the switches covered in this guide have CDP enabled on each port.
This is a read-only capability, meaning that the switch can receive and store
information about adjacent CDP devices but does not generate CDP packets.
When a CDP-enabled switch receives a CDP packet from another CDP device,
it enters that device’s data in the CDP Neighbors table, along with the port
number where the data was received (and does not forward the packet). The
switch also periodically purges the table of any entries that have expired. (The
hold time for any data entry in the switch’s CDP Neighbors table is configured
in the device transmitting the CDP packet, and cannot be controlled in the
switch receiving the packet.) A switch reviews the list of CDP neighbor entries
every three seconds, and purges any expired entries.

Overview
Overview
The switches covered in this guide support several methods for transferring
files to and from a physically connected device, or via the network, including
TFTP and Xmodem. This appendix explains how to download new switch
software, upload or download switch configuration files and software images.
It contains the following information:
■ Downloading switch software (begins on this page)
■ Copying software images (page A-22)
■ Transferring switch configurations (begins on page A-23)
■ Copying diagnostic data (begins on page A-28)
Downloading Switch Software
ProCurve periodically provides switch software updates through the Pro-
Curve Networking web site. For more information, refer to the support and
warranty booklet shipped with the switch, or visit www.procurve.com and click
on software updates. After you acquire a new software version, you can use
one of the following methods for downloading software to the switch:
Software Download Feature Default Menu CLI Web
TFTP n/a page A-4 page A-7 —
Xmodem n/a page A-17 page A-18 —
Switch-to-Switch n/a page A-19 page A-20 —
Software Update Manager in PCM+ Refer to the documentation provided with PCM+.
Note This manual uses the terms switch software and software image to refer to
the downloadable software files the switch uses to operate its networking
features. Other terms sometimes include Operating System, or OS.
General Software Download Rules
■ Switch software that you download via the menu interface always goes
to primary flash.
■ After a software download, you must reboot the switch to implement the
new software. Until a reboot occurs, the switch continues to run on the
software it was using before the download commenced.
A-3
File Transfers
Downloading Switch Software
Note Downloading new switch software does not change the current switch con-
figuration. The switch configuration is contained in separate files that can also
be transferred. Refer to “Transferring Switch Configurations” on page A-22.
In most cases, if a power failure or other cause interrupts a flash image
download, the switch reboots with the image previously stored in primary
flash. In the unlikely event that the primary image is corrupted (which may
occur if a download is interrupted by a power failure), the switch goes into
boot ROM mode. In this case, use the boot ROM console to download a new
image to primary flash. Refer to “Restoring a Flash Image” on page C-68.
Using TFTP To Download Switch Software from a
Server
This procedure assumes that:
■ A software version for the switch has been stored on a TFTP server
accessible to the switch. (The software file is typically available from the
ProCurve Networking web site at www.procurve.com.)
■ The switch is properly connected to your network and has already been
configured with a compatible IP address and subnet mask.
■ The TFTP server is accessible to the switch via IP.
Before you use the procedure, do the following:
■ Obtain the IP address of the TFTP server in which the software file has
been stored.
■ If VLANs are configured on the switch, determine the name of the VLAN
in which the TFTP server is operating.
■ Determine the name of the software file stored in the TFTP server for the
switch (for example, E0820.swi).
Note If your TFTP server is a UNIX workstation, ensure that the case (upper or
lower) that you specify for the filename is the same case as the characters
in the software filenames on the server.
Menu: TFTP Download from a Server to Primary Flash
Note that the menu interface accesses only the primary flash.
1. In the console Main Menu, select Download OS to display the screen in
figure A-1. (The term “OS”, or “operating system” refers to the switch
software):

Figure A-1. Example of a Download OS (Software) Screen (Default Values)
2. Press [E] (for Edit).
3. Ensure that the Method field is set to TFTP (the default).
4. In the TFTP Server field, type in the IP address of the TFTP server in which
the software file has been stored.
5. In the Remote File Name field, type the name of the software file. If you
are using a UNIX system, remember that the filename is case-sensitive.
6. Press [Enter], then [X] (for eXecute) to begin the software download. The
following screen then appears:
Figure A-2. Example of the Download OS (Software) Screen During a Download
A “progress” bar indicates the progress of the download. When the entire
software file has been received, all activity on the switch halts and you
will see Validating and writing system software to FLASH...
A-5
File Transfers
Downloading Switch Software
7. After the primary flash memory has been updated with the new software,
you must reboot the switch to implement the newly downloaded software.
Return to the Main Menu and press [6] (for Reboot Switch). You will then
see this prompt:
Continue reboot of system? : No
Press the space bar once to change No to Yes, then press [Enter] to begin
the reboot.
Note When you use the menu interface to download a switch software, the new
image is always stored in primary flash. Also, using the Reboot Switch
command in the Main Menu always reboots the switch from primary flash.
Rebooting the switch from the CLI gives you more options. Refer to
“Rebooting the Switch” on page 6-18.
8. After you reboot the switch, confirm that the software downloaded cor-
rectly:
a. From the Main Menu, select 1. Status and Counters, and from the Status
and Counters menu, select 1. General System Information
b. Check the Firmware revision line.
Troubleshooting TFTP Download Failures. When using the menu inter-
face, if a TFTP download fails, the Download OS (Operating System, or
software) screen indicates the failure.

File Transfers
Downloading Switch Software
To find more information on the cause of a download failure, examine the
messages in the switch’s Event Log by executing the show log tftp command
from the CLI. Also:
■ For more on the Event Log, see “Using the Event Log for Troubleshooting
Switch Problems” on page C-22.
■ For descriptions of individual Event Log messages, refer to the latest
version of the Event Log Message Reference Guide for your switch,
available on the ProCurve website. (See also “Getting Documentation
From the Web” on page 1-6.)
Some of the causes of download failures include:
■ Incorrect or unreachable address specified for the TFTP Server parameter.
This may include network problems.
■ Incorrect VLAN.
■ Incorrect name specified for the Remote File Name parameter, or the
specified file cannot be found on the TFTP server. This can also occur if
the TFTP server is a UNIX machine and the case (upper or lower) for the
filename on the server does not match the case for the filename entered
for the Remote File Name parameter in the Download OS (Operating System,
or software) screen.
■ One or more of the switch’s IP configuration parameters are incorrect.
■ For a UNIX TFTP server, the file permissions for the software file do not
allow the file to be copied.
■ Another console session (through either a direct connection to a terminal
device or through Telnet) was already running when you started the
session in which the download was attempted.
Note If an error occurs in which normal switch operation cannot be restored, the
switch automatically reboots itself. In this case, an appropriate message is
displayed after the switch reboots.
CLI: TFTP Download from a Server to Flash
Syntax: copy tftp flash <ip-address> <remote-file> [< primary | secondary >]
This command automatically downloads a switch software
file to primary or secondary flash. Note that if you do not
specify the flash destination, the TFTP download defaults to
primary flash.
A-7
File Transfers
Downloading Switch Software
For example, to download a switch software file named k0800.swi from a
TFTP server with the IP address of 10.28.227.103 to primary flash:
1. Execute copy as shown below:
Dynamic counter continually displays the
number of bytes transferred.
This message means that the image you
want to upload will replace the image
currently in primary flash.
Figure A-4. Example of the Command to Download an OS (Switch Software)
2. When the switch finishes downloading the software file from the server,
it displays this progress message:
Validating and Writing System Software to FLASH …
3. When the download finishes, you must reboot the switch to implement
the newly downloaded software image. To do so, use one of the following
commands:
Syntax: boot system flash < primary | secondary >
Boots from the selected flash.
Syntax: reload
Boots from the flash image and startup-config file. A switch
covered in this guide (with multiple configuration files), also
uses the current startup-config file.
(For more on these commands, refer to “Rebooting the Switch” on page
6-18.)
4. To confirm that the software downloaded correctly, execute show system
and check the Firmware revision line.
For information on primary/secondary flash memory and the boot commands,
refer to “Using Primary and Secondary Flash Image Options” on page 6-13.
Note If you use auto-tftp to download a new image in a redundant management
system, the active management module downloads the new image to both the
active and standby modules. Rebooting after the auto-tftp process completes
reboots the entire system.

Using Secure Copy and SFTP
For some situations you may want to use a secure method to issue commands
or copy files to the switch. By opening a secure, encrypted SSH session you
can then use a third-party software application to take advantage of Secure
Copy (SCP) and Secure ftp (SFTP). SCP and SFTP provide a secure alternative
to TFTP for transferring information that may be sensitive (like switch con-
figuration files) to and from the switch. Essentially you are creating a secure
SSH tunnel as a way to transfer files with SFTP and SCP channels.
To use these commands you must install on the administrator workstation a
third-party application software client that supports the SFTP and/or SCP
functions. Some examples of software that supports SFTP and SCP are
PuTTY, Open SSH, WinSCP, and SSH Secure Shell. Most of these are freeware
and may be downloaded without cost or licensing from the internet. There are
differences in the way these clients work, so be sure you also download the
documentation.
As described earlier in this chapter you can use a TFTP client on the admin-
istrator workstation to update software images. This is a plain text mechanism
and it connects to a standalone TFTP server or another ProCurve switch
acting as a TFTP server to obtain the software image file(s). Using SCP and
SFTP allows you to maintain your switches with greater security. You can also
roll out new software images with automated scripts that make it easier to
upgrade multiple switches simultaneously and securely.
SFTP (secure file transfer protocol) is unrelated to FTP, although there are
some functional similarities. Once you set up an SFTP session through an SSH
tunnel, some of the commands are the same as FTP commands. Certain
commands are not allowed by the SFTP server on the switch, such as those
that create files or folders. If you try to issue commands such as create or
remove using SFTP the switch server returns an error message.
You can use SFTP just as you would TFTP to transfer files to and from the
switch, but with SFTP your file transfers are encrypted and require authenti-
cation, so they are more secure than they would be using TFTP. SFTP works
only with SSH version 2 (SSH v2).
Note SFTP over SSH version 1 (SSH v1) is not supported. A request from either the
client or the switch (or both) using SSH v1 generates an error message. The
actual text of the error message differs, depending on the client software in
use. Some examples are:
Protocol major versions differ: 2 vs. 1

File Transfers
Downloading Switch Software
Protocol major versions differ: 1 vs. 2

libexec/sftp-server: command not supported
Connection closed
SCP (secure copy) is an implementation of the BSD rcp (Berkeley UNIX
remote copy) command tunneled through an SSH connection.
SCP is used to copy files to and from the switch when security is required.
SCP works with both SSH v1 and SSH v2. Be aware that the most third-party
software application clients that support SCP use SSHv1.
How It Works
The general process for using SCP and SFTP involves three steps:
1. Open an SSH tunnel between your computer and the switch if you haven’t
already done so. (This step assumes that you have already set up SSH on
the switch.)
2. Execute ip ssh filetransfer to tell the switch that you want to enable secure
file transfer.
3. Use a third-party client application for SCP and SFTP commands.
The SCP/SFTP Process
To use SCP and SFTP:
1. Open an SSH session as you normally would to establish a secure
encrypted tunnel between your computer and the switch. For more
detailed directions on how to open an SSH session refer to the chapter
titled “Configuring Secure Shell (SSH)” in the Access Security Guide for
your switch. Please note that this is a one-time procedure for new
switches or connections. If you have already done it once you should not
need to do it a second time.
2. To enable secure file transfer on the switch (once you have an SSH session
established between the switch and your computer), open a terminal
window and type in the following command:
ProCurve(config)# ip ssh filetransfer

Disable TFTP and Auto-TFTP for Enhanced Security
Using the ip ssh filetransfer command to enable Secure FTP (SFTP) automat-
ically disables TFTP and auto-TFTP (if either or both are enabled).

Figure A-5. Example of Switch Configuration with SFTP Enabled
If you enable SFTP, then later disable it, TFTP and auto-TFTP remain disabled
unless they are explicitly re-enabled.
Operating rules are:
■ The TFTP feature is enabled by default, and can be enabled or disabled
through the CLI, the Menu interface, or an SNMP application. Auto-TFTP
is disabled by default and must be configured through the CLI.

Note: If SFTP is enabled, this field will be set to No. You
cannot use this field to enable TFTP if SFTP is enabled.
Attempting to do so produces an Inconsistent value
message in the banner below the Actions line.
Figure A-6. Using the Menu Interface To Disable TFTP
■ While SFTP is enabled, TFTP and auto-TFTP cannot be enabled from the
CLI. Attempting to enable either non-secure TFTP option while SFTP is
enabled produces one of the following messages in the CLI:
SFTP must be disabled before enabling tftp.
SFTP must be disabled before enabling auto-tftp.
Similarly, while SFTP is enabled, TFTP cannot be enabled using an SNMP
management application. Attempting to do so generates an “inconsistent
value” message. (An SNMP management application cannot be used to
enable or disable auto-TFTP.)
■ To enable SFTP by using an SNMP management application, you must
first disable TFTP and, if configured, auto-TFTP on the switch. You can
use either an SNMP application or the CLI to disable TFTP, but must use
the CLI to disable auto-TFTP. The following two CLI commands disable
TFTP and auto-TFTP on the switch.
A-12
File Transfers
Downloading Switch Software
Syntax: no tftp-enable
This command disables all TFTP operation on the switch
except for the auto-TFTP feature. To re-enable TFTP opera-
tion, use the tftp-enable command. When TFTP is disabled,
the instances of tftp in the CLI copy command and the Menu
interface “Download OS” screen become unavailable.
Note: This command does not disable auto-TFTP operation.
To disable an auto-TFTP command configured on the
switch, use the no auto-tftp command described below to
remove the command entry from the switch’s configuration.
Syntax: no auto-tftp
If auto-TFTP is configured on the switch, this command
deletes the auto-tftp entry from the switch configuration,
thus preventing auto-tftp operation if the switch reboots.
Note: This command does not affect the current TFTP-
enable configuration on the switch.
Command Options
If you need to enable SSH v2 (which is required for SFTP) enter this command:
ProCurve(config)# ip ssh version 2
Note As a matter of policy, administrators should not enable the SSHv1-only or the
SSHv1-or-v2 advertisement modes. SSHv1 is supported on only some legacy
switches (such as the ProCurve Series 2500 switches).
To confirm that SSH is enabled type in the command
ProCurve(config)# show ip ssh
Once you have confirmed that you have enabled an SSH session (with the show
ip ssh command) you can then open your third-party software client applica-
tion to begin using the SCP or SFTP commands to safely transfer files or issue
commands to the switch.
If you need to disable secure file transfer:
ProCurve(config)# no ip ssh filetransfer
A-13
File Transfers
Downloading Switch Software
Authentication
Switch memory allows up to ten public keys. This means the authentication
and encryption keys you use for your third-party client SCP/SFTP software
can differ from the keys you use for the SSH session, even though both SCP
and SFTP use a secure SSH tunnel.
Note SSH authentication is mutually exclusive with RADIUS servers.
Some clients such as PSCP (PuTTY SCP) automatically compare switch host
keys for you. Other clients require you to manually copy and paste keys to the
$HOME/.ssh/known_hosts file. Whatever SCP/SFTP software tool you use, after
installing the client software you must verify that the switch host keys are
available to the client.
Because the third-party software utilities you may use for SCP/SFTP vary, you
should refer to the documentation provided with the utility you select before
performing this process.
SCP/SFTP Operating Notes
■ Any attempts to use SCP or SFTP without using ip ssh filetransfer will cause
the SCP or SFTP session to fail. Depending on the client software in use,
you will receive an error message on the originating console, for example:
IP file transfer not enabled on the switch
■ There is a delay when SFTP is copying an image onto the switch, and
although the command prompt returns in a couple of seconds, the switch
may take approximately a minute and half writing the image to flash. You
can keep entering the show flash command to see when the copy is
complete and the flash is updated. You can also check the log for an entry
similar to the following:
I 01/09/09 16:17:07 00150 update: Primary Image
updated.
I 01/09/09 16:13:22 00636 ssh: sftp session from
15.22.22.03
■ When an SFTP client connects, the switch provides a file system display-
ing all of its available files and folders. No file or directory creation is
permitted by the user. Files may only be uploaded or downloaded, accord-
ing to the permissions mask. All of the necessary files the switch will need
are already in place on the switch. You do not need to (nor can you create)
new files.
A-14

■ The switch supports one SFTP session or one SCP session at a time.
■ All files have read-write permission. Several SFTP commands, such as
create or remove, are not allowed and return an error message. The
switch displays the following files:

Troubleshooting SSH, SFTP, and SCP Operations
You can verify secure file transfer operations by checking the switch’s event
log, or by viewing the error messages sent by the switch that most SCP and
SFTP clients will print out on their console.
Note Messages that are sent by the switch to the client depend on the client software
in use to display them on the user console.
Broken SSH Connection. If an ssh connection is broken at the wrong
moment (for instance, the link goes away or spanning tree brings down the
link), a fatal exception would occur on the switch. If this happens, the switch
will gracefully exit the session and produce an event log message indicating
the cause of failure. The following three examples show the error messages
that may appear in the log depending on the type of session that is running
(SSH, SCP, or SFTP).
ssh: read error Bad file number, session aborted I 01/
01/90 00:06:11 00636 ssh: sftp session from
::ffff:10.0.12.35 W 01/01/90 00:06:26 00641 ssh:
sftp read error Bad file number, session aborted I 01/
01/90 00:09:54 00637 ssh: scp session from
::ffff:10.0.12.35 W 01/01/90
ssh: scp read error Bad file number, session aborted
Note The Bad file number is from the system error value and may differ
depending on the cause of the failure. In the third example, the device file to
read was closed as the device read was about to occur.
Attempt to Start a Session During a Flash Write. If you attempt to
start an SCP (or SFTP) session while a flash write is in progress, the switch
will not allow the SCP or SFTP session to start. Depending on the client
software in use, the following error message may appear on the client console:
Received disconnect from 10.0.12.31: 2: Flash access
in progress
lost connection
Failure to Exit from a Previous Session. This next example shows the
error message that may appear on the client console if a new SCP (or SFTP)
session is started from a client before the previous client session has been
closed (the switch requires approximately ten seconds to timeout the previous
session):
A-16
File Transfers
Downloading Switch Software
Received disconnect from 10.0.12.31: 2: Wait for

Attempt to Start a Second Session. The switch supports only one SFTP
session or one SCP session at a time. If a second session is initiated (for
example, an SFTP session is running and then an SCP session is attempted),
then the following error message may appear on the client console:
Received disconnect from 10.0.12.31: 2: Other SCP/SFTP
session running
lost connection
Using Xmodem to Download Switch Software From
a PC or UNIX Workstation
This procedure assumes that:
■ The switch is connected via the Console RS-232 port to a PC operating as
a terminal. (Refer to the Installation and Getting Started Guide you
received with the switch for information on connecting a PC as a terminal
and running the switch console interface.)
■ The switch software is stored on a disk drive in the PC.
■ The terminal emulator you are using includes the Xmodem binary transfer
feature. (For example, in the HyperTerminal application included with
Windows NT, you would use the Send File option in the Transfer dropdown
menu.)

For example, using HyperTerminal:
a. Click on Transfer, then Send File.
b. Type the file path and name in the Filename field.
c. In the Protocol field, select Xmodem.
d. Click on the [Send] button.
The download can take several minutes, depending on the baud rate used
in the transfer.
3. When the download finishes, you must reboot the switch to implement
the newly downloaded software. To do so, use one of the following
commands:
Syntax: boot system flash <primary | secondary>
Reboots from the selected flash.
Syntax: reload
Reboots from the flash image currently in use.
(For more on these commands, see “Rebooting the Switch” on page 6-18.)
Switch-to-Switch Download
You can use TFTP to transfer a software image between two switches of the
same series. The menu interface enables you to transfer primary-to-primary
or secondary-to-primary. The CLI enables all combinations of flash location
options.
Menu: Switch-to-Switch Download to Primary Flash
Using the menu interface, you can download a switch software file from either
the primary or secondary flash of one switch to the primary flash of another
switch of the same series.
1. From the switch console Main Menu in the switch to receive the down-
load, select 7. Download OS screen.
2. Ensure that the Method parameter is set to TFTP (the default).

3. In the TFTP Server field, enter the IP address of the remote switch contain-
ing the software file you want to download.
4. For the Remote File Name, enter one of the following:
• To download the software in the primary flash of the source switch,
type “flash” in lowercase characters.
• To download the software in the secondary flash of the source switch,
type
/os/secondary.
5. Press [Enter], then [X] (for eXecute) to begin the software download.
6. A “progress” bar indicates the progress of the download. When the entire
switch software download has been received, all activity on the switch
halts and the following messages appear:

b. Check the Firmware revision line.
CLI: Switch-To-Switch Downloads
Where two switches in your network belong to the same series, you can
download a software image between them by initiating a copy tftp command
from the destination switch. The options for this CLI feature include:
■ Copy from primary flash in the source to either primary or secondary in
the destination.
■ Copy from either primary or secondary flash in the source to either
primary or secondary flash in the destination.
A-20
File Transfers
Downloading Switch Software
Downloading from Primary Only.
Syntax: copy tftp flash < ip-addr > flash [ primary | secondary ]
This command (executed in the destination switch)
downloads the software flash in the source switch’s primary
flash to either the primary or secondary flash in the
destination switch.
If you do not specify either a primary or secondary flash location for the
destination, the download automatically goes to primary flash.
For example, to download a software file from primary flash in a switch with
an IP address of 10.29.227.103 to the primary flash in the destination switch,
you would execute the following command in the destination switch’s CLI:
Running Total

Downloading from Either Flash in the Source Switch to Either Flash
in the Destination Switch.
Syntax: copy tftp flash < ip-addr > < /os/primary > | < /os/secondary > [ primary |
secondary ]
This command (executed in the destination switch) gives you
the most options for downloading between switches. If you do
not specify either a primary or secondary flash location for
the destination, the download automatically goes to primary
flash.
For example, to download a software file from secondary flash in a switch
with an IP address of 10.28.227.103 to the secondary flash in a destination
switch, you would execute the following command in the destination switch’s
CLI:

TFTP: Copying a Customized Command File to a Switch
Using the copy tftp command with the show-tech option provides the ability to
copy a customized command file to the switch. When the show tech custom
command is executed, the commands in the custom file are executed instead
of the hard-coded list of commands. If no custom file is found, the current
hard-coded list is executed. This list contains commands to display data such
as the image stamp, running configuration, boot history, port settings, and so
on.
Syntax: copy tftp show-tech <ipv4 or ipv6 address> <filename>
Copy a customized command file to the switch.
ProCurve(config)# copy tftp show-tech 10.10.10.3 commandfile1

does not affect the cumulative values in the actual hardware counters. (In
compliance with the SNMP standard, the values in the hardware counters are
not reset to zero unless you reboot the switch.) Thus, using the Reset action
resets the displayed counters to zero for the current session only. Exiting from
the console session and starting a new session restores the counter displays
to the accumulated values in the hardware counters.

You can designate monitoring of inbound and outbound traffic on ports and
static trunks. The switch monitors network activity by copying all traffic
inbound and outbound on the specified interfaces to the designated monitor-
ing port, to which a network analyzer can be attached.
If a tagged packet arrives on a monitored port, the packet will remain tagged
when it goes out a monitored port even if that port is configured as untagged.
If the packet is untagged, it will remain untagged going out the monitor port.
The monitor port state (tagged or untagged) does not affect the tagging of the
packet. However, egress mirroring does not reflect the tagged or untagged
characteristic to the mirror port, instead it reflects the tagged or untagged
characteristic of the mirror port.
Note When both inbound and outbound monitoring is done, and IGMP is enabled
on any VLAN, you may get two copies of IGMP packets on the monitored port.
Note VLANs and port trunks cannot be used as a monitoring port.
The switch can monitor static LACP trunks, but not dynamic LACP trunks.
It is possible, when monitoring multiple interfaces in networks with high
traffic levels, to copy more traffic to a monitor port than the link can support.
In this case, some packets may not be copied to the monitor port.

Overview
Overview
This appendix addresses performance-related network problems that can be
caused by topology, switch configuration, and the effects of other devices or
their configurations on switch operation. (For switch-specific information on
hardware problems indicated by LED behavior, cabling requirements, and
other potential hardware-related problems, refer to the Installation Guide
you received with the switch.)
Note ProCurve periodically places switch software updates on the ProCurve
Networking web site. ProCurve recommends that you check this web site for
software updates that may have fixed a problem you are experiencing.
For information on support and warranty provisions, refer to the Support and
Warranty booklet shipped with the switch.

Troubleshooting Approaches
Troubleshooting Approaches
Use these approaches to diagnose switch problems:
■ Check the ProCurve Networking web site for software updates that may
have solved your problem: www.procurve.com
■ Check the switch LEDs for indications of proper switch operation:
• Each switch port has a Link LED that should light whenever an active
network device is connected to the port.
• Problems with the switch hardware and software are indicated by
flashing the Fault and other switch LEDs.
Refer to the Installation Guide shipped with the switch for a descrip-
tion of the LED behavior and information on using the LEDs for
troubleshooting.
■ Check the network topology/installation. Refer to the Installation Guide
shipped with the switch for topology information.
■ Check cables for damage, correct type, and proper connections. You
should also use a cable tester to check your cables for compliance to the
relevant IEEE 802.3 specification. Refer to the Installation Guide shipped
with the switch for correct cable types and connector pin-outs.
■ Use ProCurve Manager to help isolate problems and recommend solu-
tions.
■ Use the Port Utilization Graph and Alert Log in the web browser interface
included in the switch to help isolate problems. Refer to Chapter 5, “Using
the ProCurve Web Browser Interface” for operating information. These
tools are available through the web browser interface:
• Port Utilization Graph
• Alert Log
• Port Status and Port Counters screens
• Diagnostic tools (Link test, Ping test, configuration file browser)
■ For help in isolating problems, use the easy-to-access switch console built
into the switch or Telnet to the switch console. Refer to chapters 3 and 4
for operating information on the Menu and CLI interfaces included in the
console. These tools are available through the switch console
• Status and Counters screens
• Event Log
• Diagnostics tools (Link test, Ping test, configuration file browser, and
advanced user commands)

Unusual Network Activity
Unusual Network Activity
Network activity that fails to meet accepted norms may indicate a hardware
problem with one or more of the network components, possibly including the
switch. Such problems can also be caused by a network loop or simply too
much traffic for the network as it is currently designed and implemented.
Unusual network activity is usually indicated by the LEDs on the front of the
switch or measured with the switch console interface or with a network
management tool such as ProCurve Manager. Refer to the Installation Guide
you received with the switch for information on using LEDs to identify unusual
network activity.
A topology loop can also cause excessive network activity. The Event Log
“FFI” messages can be indicative of this type of problem.
General Problems
The network runs slow; processes fail; users cannot access servers or
other devices. Broadcast storms may be occurring in the network. These
may be due to redundant links between nodes.
• If you are configuring a port trunk, finish configuring the ports in the
trunk before connecting the related cables. Otherwise you may inad-
vertently create a number of redundant links (i.e. topology loops) that
will cause broadcast storms.
• Turn on Spanning Tree Protocol to block redundant links (i.e.
topology loops)
• Check for FFI messages in the Event Log.
Duplicate IP Addresses. This is indicated by this Event Log message:
ip: Invalid ARP source: IP address on IP address
where: both instances of IP address are the same address, indicating the
switch’s IP address has been duplicated somewhere on the network.
Duplicate IP Addresses in a DHCP Network. If you use a DHCP server
to assign IP addresses in your network and you find a device with a valid IP
address that does not appear to communicate properly with the server or other
devices, a duplicate IP address may have been issued by the server. This can
occur if a client has not released a DHCP-assigned IP address after the
intended expiration time and the server “leases” the address to another device.
C-8
Troubleshooting
Unusual Network Activity
This can also happen, for example, if the server is first configured to issue IP
addresses with an unlimited duration, then is subsequently configured to issue
IP addresses that will expire after a limited duration. One solution is to
configure “reservations” in the DHCP server for specific IP addresses to be
assigned to devices having specific MAC addresses. For more information,
refer to the documentation for the DHCP server.
One indication of a duplicate IP address in a DHCP network is this Event Log
message:
ip: Invalid ARP source: < IP-address > on <IP-address >
where: both instances of IP-address are the same address, indicating the
IP address that has been duplicated somewhere on the network.
The Switch Has Been Configured for DHCP/Bootp Operation, But Has
Not Received a DHCP or Bootp Reply. When the switch is first config-
ured for DHCP/Bootp operation, or if it is rebooted with this configuration, it
immediately begins sending request packets on the network. If the switch does
not receive a reply to its DHCP/Bootp requests, it continues to periodically
send request packets, but with decreasing frequency. Thus, if a DHCP or Bootp
server is not available or accessible to the switch when DHCP/Bootp is first
configured, the switch may not immediately receive the desired configuration.
After verifying that the server has become accessible to the switch, reboot the
switch to re-start the process.
802.1Q Prioritization Problems
Ports configured for non-default prioritization (level 1 - 7) are not
performing the specified action. If the ports were placed in a trunk group
after being configured for non-default prioritization, the priority setting was
automatically reset to zero (the default). Ports in a trunk group operate only
at the default priority setting.
IGMP-Related Problems
IP Multicast (IGMP) Traffic That Is Directed By IGMP Does Not Reach
IGMP Hosts or a Multicast Router Connected to a Port. IGMP must
be enabled on the switch and the affected port must be configured for “Auto”
or “Forward” operation.
C-9
Troubleshooting
Unusual Network Activity
Caution
Note
IP Multicast Traffic Floods Out All Ports; IGMP Does Not Appear To
Filter Traffic. The IGMP feature does not operate if the switch or VLAN does
not have an IP address configured manually or obtained through DHCP/Bootp.
To verify whether an IP address is configured for the switch or VLAN, do either
of the following:
■ Try Using the Web Browser Interface: If you can access the web
browser interface, then an IP address is configured.
■ Try To Telnet to the Switch Console: If you can Telnet to the switch,
then an IP address is configured.
■ Using the Switch Console Interface: From the Main Menu, check the
Management Address Information screen by clicking on
1. Status and Counters
2. Switch Management Address Information
LACP-Related Problems
Unable to enable LACP on a port with the interface < port-number > lacp
command. In this case, the switch displays the following message:
Operation is not allowed for a trunked port.
You cannot enable LACP on a port while it is configured as static Trunk port.
To enable LACP on static-trunked port, first use the
no trunk < port-number > command to disable the static trunk assignment, then
execute interface < port-number > lacp.
Removing a port from a trunk without first disabling the port can create a
traffic loop that can slow down or halt your network. Before removing a port
from a trunk, ProCurve recommends that you either disable the port or
disconnect it from the LAN.
Port-Based Access Control (802.1X)-Related Problems
To list the 802.1X port-access Event Log messages stored on the switch, use
show log 802.
See also “Radius-Related Problems” on page C-14.
C-10
Troubleshooting
Unusual Network Activity
The switch does not receive a response to RADIUS authentication
requests. In this case, the switch will attempt authentication using the
secondary method configured for the type of access you are using (console,
Telnet, or SSH).
There can be several reasons for not receiving a response to an authentication
request. Do the following:
■ Use ping to ensure that the switch has access to the configured RADIUS
servers.
■ Verify that the switch is using the correct encryption key (RADIUS secret
key) for each server.
■ Verify that the switch has the correct IP address for each RADIUS server.
■ Ensure that the radius-server timeout period is long enough for network
conditions.
The switch does not authenticate a client even though the RADIUS
server is properly configured and providing a response to the
authentication request. If the RADIUS server configuration for authenti-
cating the client includes a VLAN assignment, ensure that the VLAN exists as
a static VLAN on the switch. Refer to “How 802.1X Authentication Affects
VLAN Operation” in the Access Security Guide for your switch.
During RADIUS-authenticated client sessions, access to a VLAN on the
port used for the client sessions is lost. If the affected VLAN is config-
ured as untagged on the port, it may be temporarily blocked on that port during
an 802.1X session. This is because the switch has temporarily assigned another
VLAN as untagged on the port to support the client access, as specified in the
response from the RADIUS server. Refer to “How 802.1X Authentication
Affects VLAN Operation” in the Access Security Guide for your switch.
The switch appears to be properly configured as a supplicant, but
cannot gain access to the intended authenticator port on the switch
to which it is connected. If aaa authentication port-access is configured for
Local, ensure that you have entered the local login (operator-level) username
and password of the authenticator switch into the identity and secret parame-
ters of the supplicant configuration. If instead, you enter the enable (manager-
level) username and password, access will be denied.
C-11
Troubleshooting
Unusual Network Activity
The supplicant statistics listing shows multiple ports with the same
authenticator MAC address. The link to the authenticator may have been
moved from one port to another without the supplicant statistics having been
cleared from the first port. Refer to “Note on Supplicant Statistics” in the
chapter on Port-Based and User-Based Access Control in the Access Security
Guide for your switch.
The show port-access authenticator < port-list > command shows one or more
ports remain open after they have been configured with control
unauthorized. 802.1X is not active on the switch. After you execute aaa port-
access authenticator active, all ports configured with control unauthorized
should be listed as Closed.
Port A9 shows an “Open” status even
though Access Control is set to
Unauthorized (Force Auth). This is
because the port-access
authenticator has not yet been
activated.

RADIUS server fails to respond to a request for service, even though
the server’s IP address is correctly configured in the switch. Use
show radius to verify that the encryption key (RADIUS secret key) the switch
is using is correct for the server being contacted. If the switch has only a global
key configured, then it either must match the server key or you must configure
a server-specific key. If the switch already has a server-specific key assigned
to the server’s IP address, then it overrides the global key and must match the
server key.

Also, ensure that the switch port used to access the RADIUS server is not
blocked by an 802.1X configuration on that port. For example, show port-
access authenticator < port-list > gives you the status for the specified ports.
Also, ensure that other factors, such as port security or any 802.1X configura-
tion on the RADIUS server are not blocking the link.
The authorized MAC address on a port that is configured for both
802.1X and port security either changes or is re-acquired after
execution of aaa port-access authenticator < port-list > initialize. If the port is
force-authorized with aaa port-access authenticator <port-list> control authorized
command and port security is enabled on the port, then executing initialize
causes the port to clear the learned address and learn a new address from the
first packet it receives after you execute initialize.
A trunked port configured for 802.1X is blocked. If you are using
RADIUS authentication and the RADIUS server specifies a VLAN for the port,
the switch allows authentication, but blocks the port. To eliminate this
problem, either remove the port from the trunk or reconfigure the RADIUS
server to avoid specifying a VLAN.
QoS-Related Problems
Loss of communication when using VLAN-tagged traffic. If you cannot
communicate with a device in a tagged VLAN environment, ensure that the
device either supports VLAN tagged traffic or is connected to a VLAN port that

Spanning-Tree Protocol (MSTP) and Fast-Uplink
Problems
Caution If you enable MSTP, it is recommended that you leave the remainder of the
MSTP parameter settings at their default values until you have had an oppor-
tunity to evaluate MSTP performance in your network. Because incorrect
MSTP settings can adversely affect network performance, you should avoid
making changes without having a strong understanding of how MSTP oper-
ates. To learn the details of MSTP operation, refer to the IEEE 802.1s standard.
Broadcast Storms Appearing in the Network. This can occur when
there are physical loops (redundant links) in the topology.Where this exists,
you should enable MSTP on all bridging devices in the topology in order for
the loop to be detected.
STP Blocks a Link in a VLAN Even Though There Are No Redundant
Links in that VLAN. In 802.1Q-compliant switches MSTP blocks redundant
physical links even if they are in separate VLANs. A solution is to use only one,
multiple-VLAN (tagged) link between the devices. Also, if ports are available,
you can improve the bandwidth in this situation by using a port trunk. Refer
to “Spanning Tree Operation with VLANs” in the chapter titled “Static Virtual
LANs (VLANs)” in the Advanced Traffic Management Guide for your switch.
Fast-Uplink Troubleshooting. Some of the problems that can result from
incorrect usage of Fast-Uplink MSTP include temporary loops and generation
of duplicate packets.
Problem sources can include:
■ Fast-Uplink is configured on a switch that is the MSTP root device.
■ Either the Hello Time or the Max Age setting (or both) is too long on one or
more switches. Return the Hello Time and Max Age settings to their default
values (2 seconds and 20 seconds, respectively, on a switch).
■ A “downlink” port is connected to a switch that is further away (in hop
count) from the root device than the switch port on which fast-uplink
MSTP is configured.
■ Two edge switches are directly linked to each other with a fast-uplink
(Mode = Uplink) connection.
■ Fast uplink is configured on both ends of a link.
■ A switch serving as a backup MSTP root switch has ports configured for
fast-uplink MSTP and has become the root device due to a failure in the
original root device.

SSH-Related Problems
Switch access refused to a client. Even though you have placed the
client’s public key in a text file and copied the file (using the copy tftp pub-key-
file command) into the switch, the switch refuses to allow the client to have
access. If the source SSH client is an SSHv2 application, the public key may
be in the PEM format, which the switch (SSHv1) does not interpret. Check the
SSH client application for a utility that can convert the PEM-formatted key
into an ASCII-formatted key.
Executing IP SSH does not enable SSH on the switch. The switch
does not have a host key. Verify by executing show ip host-public-key. If you
see the message
ssh cannot be enabled until a host key is configured
(use 'crypto' command).
then you need to generate an SSH key pair for the switch. To do so, execute
crypto key generate.(Refer to “2. Generating the Switch’s Public and Private
Key Pair” in the SSH chapter of the Access Security Guide for your switch.)
Switch does not detect a client’s public key that does appear in the
switch’s public key file (show ip client-public-key). The client’s public key
entry in the public key file may be preceded by another entry that does not
terminate with a new line (CR). In this case, the switch interprets the next
sequential key entry as simply a comment attached to the preceding key entry.
Where a public key file has more than one entry, ensure that all entries
terminate with a new line (CR). While this is optional for the last entry in the
file, not adding a new line to the last entry creates an error potential if you
either add another key to the file at a later time or change the order of the keys
in the file.
An attempt to copy a client public-key file into the switch has failed
and the switch lists one of the following messages.
Download failed: overlength key in key file.
Download failed: too many keys in key file.
Download failed: one or more keys is not a valid RSA
public key.

Troubleshooting
Unusual Network Activity
The public key file you are trying to download has one of the following
problems:
■ A key in the file is too long. The maximum key length is 1024 characters,
including spaces. This could also mean that two or more keys are merged
together instead of being separated by a <CR><LF>.
■ There are more than ten public keys in the key file.
■ One or more keys in the file is corrupted or is not a valid rsa public key.
Client ceases to respond (“hangs”) during connection phase. The
switch does not support data compression in an SSH session. Clients will often
have compression turned on by default, but will disable it during the negotia-
tion phase. A client which does not recognize the compression-request
FAILURE response may fail when attempting to connect. Ensure that
compression is turned off before attempting a connection to prevent this
problem.
TACACS-Related Problems
Event Log. When troubleshooting TACACS+ operation, check the switch’s
Event Log for indications of problem areas.
All Users Are Locked Out of Access to the Switch. If the switch is func-
tioning properly, but no username/password pairs result in console or Telnet
access to the switch, the problem may be due to how the TACACS+ server
and/or the switch are configured. Use one of the following methods to recover:
■ Access the TACACS+ server application and adjust or remove the
configuration parameters controlling access to the switch.
■ If the above method does not work, try eliminating configuration
changes in the switch that have not been saved to flash (boot-up
configuration) by causing the switch to reboot from the boot-up
configuration (which includes only the configuration changes made
prior to the last write memory command.) If you did not use write
memory to save the authentication configuration to flash, then
pressing the Reset button or cycling the power reboots the switch
with the boot-up configuration.
C-17
Troubleshooting
Unusual Network Activity
■ Disconnect the switch from network access to any TACACS+ servers
and then log in to the switch using either Telnet or direct console port
access. Because the switch cannot access a TACACS+ server, it will
default to local authentication. You can then use the switch’s local
Operator or Manager username/password pair to log on.
■ As a last resort, use the Clear/Reset button combination to reset the
switch to its factory default boot-up configuration. Taking this step
means you will have to reconfigure the switch to return it to operation
in your network.
No Communication Between the Switch and the TACACS+ Server
Application. If the switch can access the server device (that is, it can ping
the server), then a configuration error may be the problem. Some possibilities
include:
■ The server IP address configured with the switch’s tacacs-server host
command may not be correct. (Use the switch’s show tacacs-server
command to list the TACACS+ server IP address.)
■ The encryption key configured in the server does not match the
encryption key configured in the switch (by using the tacacs-server
key command). Verify the key in the server and compare it to the key
configured in the switch. (Use show tacacs-server to list the global key.
Use show config or show config running to list any server-specific keys.)
■ The accessible TACACS+ servers are not configured to provide
service to the switch.
Access Is Denied Even Though the Username/Password Pair Is
Correct. Some reasons for denial include the following parameters
controlled by your TACACS+ server application:
■ The account has expired.
■ The access attempt is through a port that is not allowed for the
account.
■ The time quota for the account has been exhausted.
■ The time credit for the account has expired.
■ The access attempt is outside of the time frame allowed for the
account.
■ The allowed number of concurrent logins for the account has been

TimeP, SNTP, or Gateway Problems
The Switch Cannot Find the Time Server or the Configured Gateway .
TimeP, SNTP, and Gateway access are through the primary VLAN, which in
the default configuration is the DEFAULT_VLAN. If the primary VLAN has
been moved to another VLAN, it may be disabled or does not have ports
assigned to it.
VLAN-Related Problems
None of the devices assigned to one or more VLANs on an 802.1Q-
compliant switch are being recognized. If multiple VLANs are being used
on ports connecting 802.1Q-compliant devices, inconsistent VLAN IDs may
have been assigned to one or more VLANs. For a given VLAN, the same VLAN
ID must be used on all connected 802.1Q-compliant devices.
Link Configured for Multiple VLANs Does Not Support Traffic for One
or More VLANs. One or more VLANs may not be properly configured as
“Tagged” or “Untagged”. A VLAN assigned to a port connecting two 802.1Q-
compliant devices must be configured the same on both ports. For example,
VLAN_1 and VLAN_2 use the same link between switch “X” and switch “Y”.

switch “A”, then it must also be configured as “Tagged” on the link port
on switch “B”. Make sure that the VLAN ID (VID) is the same on both

Duplicate MAC Addresses Across VLANs. The switches covered in this
guide operate with multiple forwarding databases. Thus, duplicate MAC
addresses occurring on different VLANs can appear where a device having
one MAC address is a member of more than one 802.1Q VLAN, and the switch
port to which the device is linked is using VLANs (instead of MSTP or trunking)
to establish redundant links to another switch. If the other device sends traffic
over multiple VLANs, its MAC address will consistently appear in multiple
VLANs on the switch port to which it is linked.
Note that attempting to create redundant paths through the use of VLANs will
cause problems with some switches. One symptom is that a duplicate MAC
address appears in the Port Address Table of one port, and then later appears
on another port. While the switches have multiple forwarding databases, and
thus does not have this problem, some switches with a single forwarding
database for all VLANs may produce the impression that a connected device
is moving among ports because packets with the same MAC address but
different VLANs are received on different ports. You can avoid this problem
by creating redundant paths using port trunks or spanning tree.

Using Log Throttling to Reduce Duplicate
Event Log and SNMP Messages
A recurring event can generate a series of duplicate Event Log messages and
SNMP traps in a relatively short time. As a result, the Event Log and any
configured SNMP trap receivers may be flooded with excessive, exactly
identical messages. To help reduce this problem, the switch uses log throttle
periods to regulate (throttle) duplicate messages for recurring events, and
maintains a counter to record how many times it detects duplicates of a
particular event since the last system reboot.
When the first instance of a particular event or condition generates a message,
the switch initiates a log throttle period that applies to all recurrences of that
event. If the logged event recurs during the log throttle period, the switch
increments the counter initiated by the first instance of the event, but does
not generate a new message.
If the logged event repeats again after the log throttle period expires, the
switch generates a duplicate of the first message, increments the counter, and
starts a new log throttle period during which any additional instances of the
event are counted, but not logged. Thus, for a particular recurring event, the
switch displays only one message in the Event Log for each log throttle period
in which the event reoccurs. Also, each logged instance of the event message
includes counter data showing how many times the event has occurred since
the last reboot. The switch manages messages to SNMP trap receivers in the
same way.
C-30
Troubleshooting
Using the Event Log for Troubleshooting Switch Problems
Log Throttle Periods
The length of the log throttle period differs according to an event’s severity
level:
Severity Level Log Throttle Period
I (Information) 6000 Seconds
W (Warning) 600 Seconds
D (Debug) 60 Seconds
M (Major) 6 Seconds
Example of Event Counter Operation
Suppose the switch detects the following after a reboot:
■ Three duplicate instances of a “Send error” during the first log throttle
period for this event
■ Five more instances of the same Send error during the second log throttle
period for this event
■ Four instances of the same Send error during the third log throttle period
for this event
In this case, the duplicate message would appear three times in the Event Log
(once for each log throttle period for the event being described), and the
Duplicate Message Counter would increment as shown in table C-2. (The same
operation would apply for messages sent to any configured SNMP trap
receivers.)
Table C-2. How the Duplicate Message Counter Increments
Instances Instances Instances Duplicate
During 1st Log During 2nd Log During 3rd Log Message
Throttle Period Throttle Period Throttle Period Counter*
3 1
5 4
4 9
*This value always comprises the first instance of the duplicate
message in the current log throttle period plus all previous occurrences
of the duplicate message occurring since the switch last rebooted.

Troubleshooting
Debug/Syslog Operation
Debug/Syslog Operation
While the Event Log records switch-level progress, status, and warning
messages on the switch, the Debug/System Logging (Syslog) feature provides
a way to record Event Log and debug messages on a remote device. For
example, you can send messages about misconfigurations and other network
protocol details to an external device, and later use them to debug network-
level problems.
Debug/Syslog Messaging
The Debug/Syslog feature allows you to specify the types of Event Log and
debug messages that you want to send to an external device. As shown in
Figure C-8, you can perform the following operations:
■ Use the debug command to configure messaging reports for the following
event types:
• Events recorded in the switch’s Event Log
• LLDP events
• SSH events
■ Use the logging command to select a subset of Event Log messages to send
to an external device for debugging purposes according to:
• Severity level
• System module
Debug/Syslog Destination Devices
To use Debug/Syslog messaging, you must configure an external device as the
logging destination by using the logging and debug destination commands. For
more information, see “Debug Destinations” on page C-40 and “Configuring a
Syslog Server” on page C-41.
A Debug/Syslog destination device can be a Syslog server and/or a console
session. You can configure debug and logging messages to be sent to:
■ Up to six Syslog servers
■ A CLI session through a direct RS-232 console connection, or a Telnet or
SSH session

Configuring Debug/Syslog Operation
1. To use a Syslog server as the destination device for debug messaging,
follow these steps:
a. Enter the logging < syslog-ip-addr > command at the global configura-
tion level to configure the Syslog server IP address and enable Syslog
logging. Optionally, you may also specify the destination subsystem
to be used on the Syslog server by entering the logging facility
command.
If no other Syslog server IP addresses are configured, entering the
logging command enables both debug messaging to a Syslog server
and the Event debug message type. As a result, the switch automati-
cally sends Event Log messages to the Syslog server, regardless of
other debug types that may be configured.
b. Re-enter the logging command in Step “a” to configure additional
Syslog servers. You can configure up to a total of six servers. (When
multiple server IP addresses are configured, the switch sends the
debug message types that you configure in Step 3 to all IP addresses.)
2. To use a CLI session on a destination device for debug messaging:
a. Set up a serial, Telnet, or SSH connection to access the switch’s CLI.
b. Enter the debug destination session command at the manager level.
3. Enable the types of debug messages to be sent to configured Syslog
servers and/or the current session device by entering the debug < debug-
type > command:
ProCurve# debug <all|destination|event|ip|ipv6
|lldp|ssh>
Repeat this step if necessary to enable multiple debug message types.
By default, Event Log messages are sent to configured debug destination
devices. To block Event Log messages from being sent, enter the no debug
event command.
4. If necessary, enable a subset of Event Log messages to be sent to config-
ured Syslog servers by specifying a severity level and/or system module
using the following commands
ProCurve(config)# logging severity < debug | major | error | warning | info >
ProCurve(config)# logging system-module < system-module >
C-35
Troubleshooting
Debug/Syslog Operation
Caution
To display a list of valid values for each command, enter logging severity
or logging system-module followed by ? or pressing the Tab key.
The severity levels in order from the highest to lowest severity are: major,
error, warning, info, debug. For a list of valid values for the logging system-
module <system-module > command, refer to Table C-1 on page C-23.
5. If you configure system-module and/or severity-level values to filter Event
Log messages, when you finish troubleshooting, you may want to reset
these values to their default settings so that the switch sends all Event Log
messages to configured debug destinations (Syslog servers and/or CLI
session).
To remove a configured setting and restore the default values that send
all Event Log messages, enter one or both of the following commands:
ProCurve(config)# no logging severity < debug | major | error | warning | info>
ProCurve(config)# no logging system-module < system-module >
If you configure a severity-level, system-module, logging destination, or
logging facility value and save the settings to the startup configuration (for
example, by entering the write memory command), the debug settings are
saved after a system reboot (power cycle or reboot) and re-activated on the
switch. As a result, after switch startup, one of the following situations may
occur:
■ Only a partial set of Event Log messages may be sent to configured debug
destinations.
■ Messages may be sent to a previously configured Syslog server used in an
earlier debugging session.
Displaying a Debug/Syslog Configuration
Use the show debug command to display the currently configured settings for:
■ Debug message types and Event Log message filters (severity level and
system module) sent to debug destinations
■ Debug destinations (Syslog servers or CLI session) and Syslog server
facility to be used
Syntax: show debug
Displays the currently configured debug logging destinations
and message types selected for debugging purposes. (If no

server facility, Event Log severity level and system module are not displayed.
However, after you configure a Syslog server address and enable Syslog

can block the messages from being sent by entering the no debug event
command. (There is no effect on the normal logging of messages in the
switch’s Event Log.)
Debug Command
At the manager level, use the debug command to perform two main functions:
■ Specifies the types of event messages to be sent to an external destination.
■ Specifies the destinations to which selected message types are sent.
By default, no debug destination is enabled and only Event Log messages are
enabled to be sent.
Note To configure a Syslog server, use the logging <syslog-ip-addr> command. For

Note: Debug messages from the switches covered in this
guide have a debug severity level. Because the default
configuration of some Syslog servers ignore Syslog
messages with the debug severity level, ensure that the
Syslog servers you want to use to receive debug messages
are configured to accept the debug level. For more informa-
tion, refer to “Operating Notes for Debug and Syslog” on
page C-47.

Enables transmission of event notification messages to the
CLI session that most recently executed this command. The
session can be on any one terminal emulation device with
serial, Telnet, or SSH access to the CLI at the Manager level
prompt (ProCurve#_ ). If more than one terminal device has
a console session with the CLI, you can redirect the desti-
nation from the current device to another device. Do so by
executing debug destination session in the CLI on the
terminal device on which you now want to display event
messages.
Event message types received on the selected CLI session are
configured with the debug < debug-type > command. (Refer
to “Debug Messages” on page C-38.)

Troubleshooting
Debug/Syslog Operation
Logging Command
At the global configuration level, the logging command allows you to enable
debug logging on specified Syslog servers and select a subset of Event Log
messages to send for debugging purposes according to:
■ Severity level
■ System module
By specifying both a severity level and system module, you can use both
configured settings to filter the Event Log messages you want to use to
troubleshoot switch or network error conditions.
Caution After you configure a Syslog server and a severity level and/or system module
to filter the Event Log messages that are sent, if you save these settings to the
startup configuration file by entering the write memory command, these debug
and logging settings are automatically re-activated after a switch reboot or
power recycle. The debug settings and destinations configured in your
previous troubleshooting session will then be applied to the current session,
which may not be desirable.
After a reboot, messages remain in the Event Log and are not deleted.
However, after a power recycle, all Event Log messages are deleted.
If you configure a severity level and/or system module to temporarily filter
Event Log messages, be sure to reset the values to their default settings by
entering the no form of the following commands to ensure that Event Log
messages of all severity levels and from all system modules are sent to
configured Syslog servers:
ProCurve(config)# no logging severity < debug | major | error | warning | info>
ProCurve(config)# no logging system-module < system-module >

notification messages to a networked device operating with Syslog server
software. Messages sent to a Syslog server can be stored to a file for later
debugging analysis.
To use the Syslog feature, you must install and configure a Syslog server
application on a networked host accessible to the switch. Refer to the docu-
mentation for the Syslog server application for instructions.
To configure a Syslog server, use the logging < syslog-ip-addr > command as
described below.
C-41
Troubleshooting
Debug/Syslog Operation
When you configure a Syslog server, Event Log messages are automatically
enabled to be sent to the server. To reconfigure this setting, use the following
commands:
■ Use debug command to specify additional debug message types (see
“Debug Messages” on page C-38).
■ Use the logging command to configure the system module or severity level
used to filter the Event Log messages sent to configured Syslog servers
(see “Configuring the Severity Level for Event Log Messages Sent to a
Syslog Server” on page C-46 and “Configuring the System Module Used to
Select the Event Log Messages Sent to a Syslog Server” on page C-47).
To display the currently configured Syslog servers as well as the types of debug
messages and the severity-level and system-module filters used to specify the
Event Log messages that are sent, enter the show debug command (see
“Displaying a Debug/Syslog Configuration” on page C-36).
C-42
Troubleshooting
Debug/Syslog Operation
Syntax: [no] logging < syslog-ip-addr >
Enables or disables Syslog messaging to the specified IP
address. You can configure up to six addresses. If you
configure an address when none are already configured, this
command enables destination logging (Syslog) and the Event
debug type. Therefore, at a minimum, the switch begins
sending Event Log messages to configured Syslog servers.
(Refer to “Debug Messages” on page C-38.)
no logging removes all currently configured Syslog logging
destinations from the running configuration.
no logging < syslog-ip-address > removes only the specified Syslog
logging destination from the running configuration.
If you use the “no” form of the command to delete the only
remaining Syslog server address, debug destination logging is
disabled on the switch, but the default Event debug type is not
changed.
Also, removing all configured Syslog destinations with the no
logging command (or a specified Syslog server destination with
the no logging < syslog-ip-address > command) does not delete the
Syslog server IP addresses stored in the startup configuration.
To delete Syslog addresses in the startup configuration, you
must enter a no logging command followed by the write memory
command. To verify the deletion of a Syslog server address,
display the startup configuration by entering the show config
command.
To block the messages sent to configured Syslog servers from
the currently configured debug message type, enter the no debug
< debug-type > command. (See “Debug Messages” on page C-38.)
To disable Syslog logging on the switch without deleting config-
ured server addresses, enter the no debug destination logging
command. Note that, unlike the case in which no Syslog servers
are configured, if one or more Syslog servers are already
configured and Syslog messaging is disabled, configuring a
new server address does not re-enable Syslog messaging. To re-
enable Syslog messaging, you must enter the debug destination
logging command.
C-43
Troubleshooting
Debug/Syslog Operation
Syntax: [no] logging facility < facility-name >
The logging facility specifies the destination subsystem used
in a configured Syslog server. (All configured Syslog servers
must use the same subsystem.) ProCurve recommends the
default (user) subsystem unless your application specifically
requires another subsystem. Options include:
user (default) — Random user-level messages
kern — Kernel messages
mail — Mail system
daemon — System daemons
auth — Security/Authorization messages
syslog — Messages generated internally by Syslog
lpr — Line-Printer subsystem
news — Netnews subsystem
uucp — uucp subsystem
cron — cron/at subsystem
sys9 — cron/at subsystem
sys10 - sys14 — Reserved for system use
local10 - local17 — Reserved for system use
Use the no form of the command to remove the configured
facility and reconfigure the default (user) value.
For a list of supported ProCurve switches, refer to the Note on
page C-34.
Adding a Description for a Syslog Server
You can associate a user-friendly description with each of the IP addresses
(IPv4 only) configured for syslog using the CLI or SNMP.
Note The HP enterprise MIB hpicfSyslog.mib allows the configuration and moni-
toring of syslog for SNMP (RFC 3164 supported).
C-44
Troubleshooting
Debug/Syslog Operation
The CLI command is:
Syntax: logging <ip-addr> control-descr <text_string>]
no logging <ip-addr> [control-descr]
An optional user-friendly description that can be associated with
a server IP address. If no description is entered, this is blank. If
<text_string> contains white space, use quotes around the string.
IPv4 addresses only. Use the no form of the command to remove
the description.
Limit: 255 characters
Note: To remove the description using SNMP, set the description
to an empty string.
ProCurve(config)# logging 10.10.10.2 control-descr syslog_one
Figure C-11. Example of the Logging Command with a Control Description
Caution Entering the no logging command removes ALL the syslog server addresses
without a verification prompt.
Adding a Priority Description
You can add a user-friendly description for the set of syslog filter parameters
using the priority-descr option. The description can be added with the CLI or
SNMP. The CLI command is:
Syntax: logging priority-descr <text_string>
no logging priority-descr
Provides a user-friendly description for the combined filter
values of severity and system module. If no description is
entered, this is blank. If <text_string> contains white space,
use quotes around the string. Use the no form of the command
to remove the description.
Limit: 255 characters

ProCurve(config)# logging priority-descr severe-pri
Figure C-12. Example of the Logging Command with a Priority Description
Note A notification is sent to the SNMP agent if there are any changes to the syslog
parameters either through the CLI or with SNMP.
Configuring the Severity Level for Event Log
Messages Sent to a Syslog Server
Event Log messages are entered with one of the following severity levels (from
highest to lowest):
Major: A fatal error condition has occurred on the switch.
Error: An error condition has occurred on the switch.
Warning: A switch service has behaved unexpectedly.
Information: Information on a normal switch event.
Debug: Reserved for ProCurve internal diagnostic information.
Using the logging severity command, you can select a set of Event Log
messages according to their severity level and send them to a Syslog server.
Messages of the selected and higher severity will be sent. To configure a Syslog
server, see “Configuring a Syslog Server” on page C-41.
Syntax: [no] logging severity < major | error l warning | info | debug >
Configures the switch to send all Event Log messages with
a severity level equal to or higher than the specified value
to all configured Syslog servers.
Default: debug (Reports messages of all severity levels.)
Use the no form of the command to remove the configured
severity level and reconfigure the default value, which sends
Event Log messages of all severity levels to Syslog servers.
Note: The severity setting does not affect event notification
messages that the switch normally sends to the Event Log.
All messages remain recorded in the Event Log.
C-46
Troubleshooting
Debug/Syslog Operation
Configuring the System Module Used to Select the Event Log
Messages Sent to a Syslog Server
Event Log messages contain the name of the system module that reported the
event. Using the logging system-module command, you can select a set of Event
Log messages according to the originating system module and send them to a
Syslog server. To configure a Syslog server, see “Configuring a Syslog Server”
on page C-41.
Using the logging system-module command, you can select messages from only
one system module to be sent to a Syslog server. You cannot configure
messages from multiple system modules to be sent. If you re-enter the
command with a different system module name, the currently configured
value is replaced with the new one.
Syntax: [no] logging system-module < system-module >
Configures the switch to send all Event Log messages being
logged from the specified system module to configured
Syslog servers.
Refer to Table C-1 on page C-27 for the correct value to enter
for each system module.
Default: all-pass (Reports all Event Log messages.)
Use the no form of the command to remove the configured
system module value and reconfigure the default value,
which sends Event Log messages from all system modules
to Syslog servers.
Note: This setting has no effect on event notification
messages that the switch normally sends to the Event Log.

■ Debug commands do not affect normal message output to the
Event Log.
Using the debug event command, you can specify that Event Log messages
are sent to the debug destinations you configure (CLI session and/or
Syslog servers) in addition to the Event Log.
■ Ensure that your Syslog servers accept Debug messages.
All Syslog messages resulting from a debug operation have a “debug”
severity level. If you configure the switch to send debug messages to a
Syslog server, ensure that the server’s Syslog application is configured to
accept the “debug” severity level. (The default configuration for some
Syslog applications ignores the “debug” severity level.)
■ Duplicate IP addresses are not stored in the list of syslog servers.
■ If the default severity value is in effect, all messages that have severities
greater than the default value are passed to syslog. For example, if the
default severity is “debug”, all messages that have severities greater than
debug are passed to syslog.
■ There is a limit of six syslog servers. All syslog servers are sent the same
messages using the same filter parameters. An error is generated for an
attempt to add more than six syslog servers.

Port Auto-Negotiation
When a link LED does not light (indicating loss of link between two devices),
the most common reason is a failure of port auto-negotiation between the
connecting ports. If a link LED fails to light when you connect the switch to a
port on another device, do the following:
1. Ensure that the switch port and the port on the attached end-node are
both set to Auto mode.
2. If the attached end-node does not have an Auto mode setting, then you
must manually configure the switch port to the same setting as the end-
node port. Refer to Chapter 10, “Port Status and Configuration”.
Ping and Link Tests
The Ping test and the Link test are point-to-point tests between your switch
and another IEEE 802.3-compliant device on your network. These tests can
tell you whether the switch is communicating properly with another device.
Note To respond to a Ping test or a Link test, the device you are trying to reach must
be IEEE 802.3-compliant.
Ping Test. This is a test of the path between the switch and another device
on the same or another IP network that can respond to IP packets (ICMP Echo
Requests). To use the ping (or traceroute) command with host names or fully
qualified domain names, refer to “DNS Resolver” on page C-71.
Link Test. This is a test of the connection between the switch and a desig-
nated network device on the same LAN (or VLAN, if configured). During the
link test, IEEE 802.2 test packets are sent to the designated network device
in the same VLAN or broadcast domain. The remote device must be able to
respond with an 802.2 Test Response Packet.

Successes indicates the number of Ping or Link packets that successfully
completed the most recent test.
Failures indicates the number of Ping or Link packets that were unsuccessful
in the last test. Failures indicate connectivity or network performance prob-
lems (such as overloaded links or devices).
Destination IP/MAC Address is the network address of the target, or destination,
device to which you want to test a connection with the switch. An IP address
is in the X.X.X.X format where X is a decimal number between 0 and 255. A
MAC address is made up of 12 hexadecimal digits, for example, 0060b0-080400.
Number of Packets to Send is the number of times you want the switch to
attempt to test a connection.

CLI: Ping Test
The Ping (Packet InterNet Groper) test uses Internet Control Message
Protocol (ICMP) echo requests and ICMP echo replies to determine if another
device is alive. It also measures the amount of time it takes to receive a reply
from the specified destination. The Ping command has several extended
commands that allow advanced checking of destination availability.
Syntax: ping <ip-address | hostname | switch-num> [repetitions <1-10000>]
[timeout <1-60>] [source <ip-address> | <vlan-id>] [data-size <0 - 65471>]

Traceroute Command
The traceroute command enables you to trace the route from the switch to a
host address.
This command outputs information for each (router) hop between the switch

uses the same default settings unless you specify otherwise for that instance
of the command.
Syntax: traceroute < ip-address | hostname >

Diagnostic Tools
<ip-address | hostname>
The IP address or hostname of the device to which to send the
traceroute.
[minttl < 1-255 >]
For the current instance of traceroute, changes the minimum
number of hops allowed for each probe packet sent along the
route. If minttl is greater than the actual number of hops, then
the output includes only the hops at and above the minttl
threshold. (The hops below the threshold are not listed.) If
minttl matches the actual number of hops, only that hop is
shown in the output. If minttl is less than the actual number
of hops, then all hops are listed. For any instance of
traceroute, if you want a minttl value other than the default,
you must specify that value. (Default: 1)
[maxttl < 1-255 >]
For the current instance of traceroute, changes the maximum
number of hops allowed for each probe packet sent along the
route. If the destination address is further from the switch
than maxttl allows, then traceroute lists the IP addresses for
all hops it detects up to the maxttl limit. For any instance of
traceroute, if you want a maxttl value other than the default,
you must specify that value. (Default: 30)
[timeout < 1-120 >]
For the current instance of traceroute, changes the timeout
period the switch waits for each probe of a hop in the route.
For any instance of traceroute, if you want a timeout value
other than the default, you must specify that value. (Default:
5 seconds)
[probes < 1-5 >]
For the current instance of traceroute, changes the number of
queries the switch sends for each hop in the route. For any
instance of traceroute, if you want a probes value other than
the default, you must specify that value. (Default: 3)
[source <ip-addr | vlan-id>]
The source IP address or VLAN. The source IP address must
be owned by the router. If a VLAN is specified, the IP address
associated with the specified VLAN is used
A Low Maxttl Causes Traceroute To Halt Before Reaching the

include:
■ Timeouts (indicated by one asterisk per probe, per hop; refer to Figure
C-17, above.)
■ Unreachable hosts
■ Unreachable networks
■ Interference from firewalls
■ Hosts configured to avoid responding
Executing traceroute where the route becomes blocked or otherwise fails
results in an output marked by timeouts for all probes beyond the last detected
hop. For example with a maximum hop count of 7 (maxttl = 7), where the route
becomes blocked or otherwise fails, the output appears similar to this:
At hop 3, the first and
third probes timed out
but the second probe
reached the router.
All further probes
within the maxttl
timed-out without
finding a router or the
destination IP
address.
An asterisk indicates a timeout
without finding the next hop.

Troubleshooting
Restoring the Factory-Default Configuration
Restoring the Factory-Default
Configuration
As part of your troubleshooting process, it may become necessary to return
the switch configuration to the factory default settings. This process momen-
tarily interrupts the switch operation, clears any passwords, clears the console
Event Log, resets the network counters to zero, performs a complete self test,
and reboots the switch into its factory default configuration including deleting
an IP address. There are two methods for resetting to the factory-default
configuration:
■ CLI
■ Clear/Reset button combination
Note ProCurve recommends that you save your configuration to a TFTP server
before resetting the switch to its factory-default configuration. You can also
save your configuration via Xmodem, to a directly connected PC.
CLI: Resetting to the Factory-Default Configuration
This command operates at any level except the Operator level.
Syntax: erase startup-configuration
Deletes the startup-config file in flash so that the switch will
reboot with its factory-default configuration.
Note The erase startup-config command does not clear passwords.
Clear/Reset: Resetting to the Factory-Default
Configuration
To execute the factory default reset, perform these steps:
1. Using pointed objects, simultaneously press both the Reset and Clear
buttons on the front of the switch.
C-67
Troubleshooting
Restoring a Flash Image
2. Continue to press the Clear button while releasing the Reset button.
3. When the Self Test LED begins to flash, release the Clear button.
The switch will then complete its self test and begin operating with the
configuration restored to the factory default settings.
Restoring a Flash Image
The switch can lose its operating system if either the primary or secondary
flash image location is empty or contains a corrupted OS file and an operator
uses the erase flash command to erase a good OS image file from the opposite
flash location.
To Recover from an Empty or Corrupted Flash State. Use the switch’s
console serial port to connect to a workstation or laptop computer that has
the following:
■ A terminal emulator program with Xmodem capability, such as the Hyper-
Terminal program included in Windows PC software.
■ A copy of a good OS image file for the switch.
Note The following procedure requires the use of Xmodem, and copies an OS image
into primary flash only.
This procedure assumes you are using HyperTerminal as your terminal
emulator. If you use a different terminal emulator, you may need to adapt this
procedure to the operation of your particular emulator.
1. Start the terminal emulator program.
2. Ensure that the terminal program is configured as follows:
■ Baud rate: 9600 ■ 1 stop bit
■ No parity ■ No flow control
■ 8 Bits

b. Change the terminal emulator baud rate to match the switch speed:
i. In HyperTerminal, select Call | Disconnect.
ii. Select File | Properties.
iii. Click on Configure.
iv. Change the baud rate to 115200.
v. Click on [OK]. In the next window, click on [OK] again.
vi. Select Call | Connect
vii. Press [Enter] one or more times to display the => prompt.
5. Start the Console Download utility by typing do at the => prompt and

7. At the above prompt:
a. Type y (for Yes)
b. Select Transfer | File in HyperTerminal.
c. Enter the appropriate filename and path for the OS image.
d. Select the Xmodem protocol (and not the 1k Xmodem protocol).
e. Click on [Send].
If you are using HyperTerminal, you will see a screen similar to the
following to indicate that the download is in progress:

Troubleshooting
DNS Resolver
DNS Resolver
The Domain Name System (DNS) resolver is designed for use in local network
domains where it enables use of a host name or fully qualified domain name
with DNS-compatible switch CLI commands.
DNS operation supports both IPv4 and IPv6 DNS resolution and multiple,
prioritized DNS servers. (For information on IPv6 DNS resolution, refer to the
latest IPv6 Configuration Guide for your switch.)
Terminology
Domain Suffix — Includes all labels to the right of the unique host name in
a fully qualified domain name assigned to an IP address. For example, in
the fully qualified domain name “device53.evergreen.trees.org”, the
domain suffix is “evergreen.trees.org”, while “device53” is the unique
(host) name assigned to a specific IP address.
Fully Qualified Domain Name — The sequence of labels in a domain name
identifying a specific host (host name) and the domain in which it exists.
For example, if a device with an IP address of 10.10.10.101 has a host name
of device53 and resides in the evergreen.trees.org domain, then the
device’s fully qualified domain name is device53.evergreen.trees.org and
the DNS resolution of this name is 10.10.10.101.
Host Name — The unique, leftmost label in a domain name assigned to a
specific IP address in a DNS server configuration. This enables the server to
distinguish a device using that IP address from other devices in the same
domain. For example, in the evergreen.trees.org domain, if an IPv4 address of
10.10.100.27 is assigned a host name of accounts015 and another IP address
of 10.10.100.33 is assigned a host name of sales021, then the switch configured
with the domain suffix evergreen.trees.org and a DNS server that resolves
addresses in that domain can use the host names to reach the devices with
DNS-compatible commands. For example:
ping accounts015
traceroute accounts015
Basic Operation
■ When the switch is configured with only the IP address of a DNS
server available to the switch, then a DNS-compatible command,
executed with a fully qualified domain name, can reach a device found
in any domain accessible through the configured DNS server.
C-71
Troubleshooting
DNS Resolver
■ When the switch is configured with both of the following:
• the IP address of a DNS server available to the switch
• the domain suffix of a domain available to the configured DNS
server
then:
• A DNS-compatible command that includes the host name of a
device in the same domain as the configured domain suffix can
reach that device.
• A DNS-compatible command that includes a fully qualified
domain name can reach a device in any domain that is available
to the configured DNS server.
Example. Suppose the switch is configured with the domain suffix
mygroup.procurve.net and the IP address for an accessible DNS server. If an
operator wants to use the switch to ping a target host in this domain by using
the DNS name “leader” (assigned by a DNS server to an IP address used in
that domain), then the operator can use either of the following commands:
ProCurve# ping leader
10.28.229.220 is alive, time = 1 ms
Host Name for the Desired Host
Ping Response
ProCurve# ping leader.mygroup.procurve.net Fully Qualified Domain Name for the
10.28.229.220 is alive, time = 1 ms Desired Host
Ping Response
Figure C-27. Example of Using Either a Host Name or a Fully Qualified Domain Name
In the proceeding example, if the DNS server’s IP address is configured on the
switch, but a domain suffix is either not configured or is configured for a
different domain than the target host, then the fully qualified domain name
must be used.
C-72
Troubleshooting
DNS Resolver
Note that if the target host is in a domain other than the domain configured
on the switch, then:
■ The host’s domain must be reachable from the switch. This requires
that the DNS server for the switch must be able to communicate with
the DNS server(s) in the path to the domain in which the target host
operates.
■ The fully qualified domain name must be used, and the domain suffix
must correspond to the domain in which the target host operates,
regardless of the domain suffix configured in the switch.
Example. Suppose the switch is configured with the domain suffix
mygroup.procurve.net and the IP address for an accessible DNS server in this
same domain. This time, the operator wants to use the switch to trace the
route to a host named “remote-01” in a different domain named
common.group.net. Assuming this second domain is accessible to the DNS
server already configured on the switch, a traceroute command using the
target’s fully qualified DNS name should succeed.
ProCurve# traceroute remote-01.common.group.net

71.) Note that if a domain suffix is not configured, fully qualified
domain names can be used to resolve DNS-compatible commands.
d. the host names assigned to target IP addresses in the DNS server for
the specified domain
2. Use the data from steps 1a through 1c to configure the DNS entry on the
switch.
3. Use a DNS-compatible command with the host name to reach the target
devices.
Configuring a DNS Entry
The switch allows up to three DNS server entries (IP addresses for DNS
servers). One domain suffix can also be configured to support resolution of
DNS names in that domain by using a host name only. Including the domain
suffix enables the use of DNS-compatible commands with a target’s host name
instead of the target’s fully qualified domain name.
Syntax: [no] ip dns server-address priority < 1 - 3 > < ip-addr >
Configures the access priority and IP address of a DNS server
accessible to the switch. These settings specify:
• the relative priority of the DNS server when multiple servers
are configured
• the IP address of the DNS server
These settings must be configured before a DNS-compatible
command can be executed with host name criteria.
The switch supports three prioritized DNS server entries.
Configuring another IP address for a priority that has already
been assigned to an IP address is not allowed. To replace one
IP address at a given priority level with another address
having the same priority, you must first use the no form of the
command to remove the unwanted address. Also, only one
instance of a given server address is allowed in the server list.
Attempting to enter a duplicate of an existing entry at a
different priority level is not allowed. To change the priority of
an existing server address, use the no form of the command to
remove the entry, then re-enter the address with the new
priority.
The no form of the command replaces the configured IP address
with the null setting. (Default: null)
C-74
Troubleshooting
DNS Resolver
Syntax: [no] ip dns domain-name < domain-name-suffix >
This optional DNS command configures the domain suffix that
is automatically appended to the host name entered with a
DNS-compatible command. When the domain suffix and the IP
address for a DNS server that can access that domain are both
configured on the switch, you can execute a DNS-compatible
command using only the host name of the desired target. (For
an example, refer to Figure C-27 on page C-72.) In either of the
following two instances, you must manually provide the
domain identification by using a fully qualified DNS name
with a DNS-compatible command:
• If the DNS server IP address is configured on the switch, but
the domain suffix is not configured (null)
• The domain suffix configured on the switch is not the
domain in which the target host exists
The switch supports one domain suffix entry and three DNS
server IP address entries. (Refer to the preceding command
description.)
The no form of the command replaces the configured domain
suffix with the null setting. (Default: null)
Example Using DNS Names with Ping and Traceroute
In the network illustrated in Figure C-29, the switch at 10.28.192.1 is config-
ured to use DNS names for DNS-compatible commands in the
pubs.outdoors.com domain. The DNS server has been configured to assign the
host name docservr to the IP address used by the document server
(10.28.229.219).

Operating Notes
■ Configuring another IP address for a priority that has already been
assigned to an IP address is not allowed. To replace one IP address at a
given priority level with another address having the same priority, you
must first use the no form of the command to remove the unwanted
address. Also, only one instance of a given server address is allowed in
the server list. Attempting to enter a duplicate of an existing entry at a
different priority level is not allowed. To change the priority of an existing
server address, use the no form of the command to remove the entry, then
re-enter the address with the new priority.
■ To change the position of an address already configured with priority x,
you must first use no ip dns server-address priority x < ip-addr > to remove
the address from the configuration, then use ip dns server-address priority
< ip-addr > to reconfigure the address with the new priority. Also, if the
priority to which you want to move an address is already used in the
configuration for another address, you must first use the no form of the
command to remove the current address from the target priority.
■ The DNS server(s) and domain configured on the switch must be
accessible to the switch, but it is not necessary for any intermediate
devices between the switch and the DNS server to be configured to
support DNS operation.
■ When multiple DNS servers are configured on the switch, they can
reside in the same domain or different domains.
■ A DNS configuration must include the IP address for a DNS server
that is able to resolve host names for the desired domain. If a DNS
server has limited knowledge of other domains, then its ability to
resolve DNS-compatible command requests is also limited.
■ If the DNS configuration includes a DNS server IP address but does
not also include a domain suffix, then any DNS-compatible
commands should include the target host’s fully qualified domain
name. Refer to Figure C-27 on page C-72.
■ Switch-Initiated DNS packets go out through the VLAN having the
best route to the DNS server, even if a Management VLAN has been
configured.
■ The DNS server address must be manually input. It is not automati-
cally determined via DHCP.

Overview
The switch assigns MAC addresses in these areas:
■ For management functions, one Base MAC address is assigned to the
default VLAN (VID = 1). (All VLANs on the switches covered in this guide
use the same MAC address.)
■ For internal switch operations: One MAC address per port (Refer to “CLI:
Viewing the Port and VLAN MAC Addresses” on page D-5.)
MAC addresses are assigned at the factory. The switch automatically
implements these addresses for VLANs and ports as they are added to the
switch.
Note The switch’s base MAC address is also printed on a label affixed to the switch.

Also, the Base MAC address appears on a label on the back of the switch.
Note The Base MAC address is used by the first (default) VLAN in the switch. This
is usually the VLAN named “DEFAULT_VLAN” unless the name has been
changed (by using the VLAN Names screen). On the switches covered in this

The MAC address assigned to each switch port is used internally by such
features as Flow Control and the spanning-tree protocol. Using the walkmib
command to determine the MAC address assignments for individual ports can
sometimes be useful when diagnosing switch operation.
The switch’s base MAC address is assigned to VLAN (VID) 1 and appears in
the walkmib listing after the MAC addresses for the ports. (All VLANs in the
switch have the same MAC address.)
To display the switch’s MAC addresses, use the walkmib command at the
command prompt:
Note This procedure displays the MAC addresses for all ports and existing VLANs
in the switch, regardless of which VLAN you select.
1. If the switch is at the CLI Operator level, use the enable command to enter
the Manager level of the CLI.

Daylight Savings Time (DST) changes. To use this feature you define the month
and date to begin and to end the change from standard time. In addition to the
value “none” (no time changes), there are five pre-defined settings, named:
■ Alaska
■ Canada and Continental US
■ Middle Europe and Portugal
■ Southern Hemisphere
■ Western Europe
The pre-defined settings follow these rules:
Alaska:
• Begin DST at 2am on the second Sunday in March.
• End DST at 2am on the first Sunday in November.

Daylight Savings Time on ProCurve Switches
Canada and Continental US:
• Begin DST at 2am on the second Sunday in March.
• End DST at 2am on the first Sunday in November.
Middle Europe and Portugal:
• Begin DST at 2am the first Sunday on or after March 25th.
• End DST at 2am the first Sunday on or after September 24th.
Southern Hemisphere:
• Begin DST at 2am the first Sunday on or after October 25th.
• End DST at 2am the first Sunday on or after March 1st.
Western Europe:
• Begin DST at 2am the first Sunday on or after March 23rd.
• End DST at 2am the first Sunday on or after October 23rd.
A sixth option named “User defined” allows you to customize the DST config-
uration by entering the beginning month and date plus the ending month and
date for the time change. The menu interface screen looks like this (all month/
date entries are at their default values):
Select User-defined and press [v] to
display the remaining parameters.

Daylight Savings Time on ProCurve Switches
Before configuring a “User defined” Daylight Time Rule, it is important to
understand how the switch treats the entries. The switch knows which dates
are Sundays, and uses an algorithm to determine on which date to change the
system clock, given the configured “Beginning day” and “Ending day”:
■ If the configured day is a Sunday, the time changes at 2am on that day.
■ If the configured day is not a Sunday, the time changes at 2am on the first
Sunday after the configured day.
This is true for both the “Beginning day” and the “Ending day”.
With that algorithm, one should use the value “1” to represent “first Sunday of
the month”, and a value equal to “number of days in the month minus 6" to
represent “last Sunday of the month”. This allows a single configuration for
every year, no matter what date is the appropriate Sunday to change the clock.

Configuring Power-Saving for LEDs
The savepower led command provides the ability to turn off the switch link,
mode, and activity LEDs and turn them on again. When power-saving is turned
off, it will turn on again automatically after 10 minutes.
Syntax: [no] savepower led
Turns power-saving option on or off for the LEDs
ProCurve(config)# savepower led
Figure F-1. Example of Setting savepower led Command
The no form of the savepower led command cancels power saving mode and
the LEDs are returned to their original state.
Show Savepower Status
To display the configured status of the LED power-saving option, use the show
savepower led command.
ProCurve(config)# show savepower led
Led Save Power Status: Enabled
