and system security.
Syntax
authentication-mode { password | scheme | none }

View
User interface view
Parameter
password: Requires local authentication of password at log in.
scheme: Requires local or remote authentication of username and password at

Description
This command configures the authentication method for a user at log in.
Use the command authentication-mode password to prompt a user for local
password authentication at login. To set the password, use set authentication
password.
Use the command authentication-mode scheme to prompt a user to provide
local or remote user name and password authentication at login. The type of the
authentication depends on your network configuration. For further information,
see “AAA and RADIUS”.
Use the command authentication-mode none to allow a user to log in without
username or password authentication.
By default, users logging in using the console port do not need to pass any
terminal authentication. Users logging in via modem or Telnet are required to
provide password authentication when they log in.
Example
To configure local password authentication, enter the following command:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]user-interface aux 0
[4500-ui-aux0]authentication-mode password

Logging in Commands

auto-execute command

Syntax
auto-execute command text
undo auto-execute command

View
User Interface View
Parameter
text: Specifies the command to be run automatically.

Description
Enter auto-execute command text to configure the Switch to automatically run a
specified command. When the user logs in, the command will be executed
automatically. This command is usually used to configure the telnet command on
the terminal, which will connect the user to a designated device automatically.
Enter undo auto-execute command to cancel the auto-execute command so the
command is not run automatically.
By default, auto-execute is disabled.
CAUTION: If you execute this command, the user-interface can no longer be used
to perform routine configurations on the local system. Ensure that you can log in
to the system in some other way to cancel the configuration, before you configure
the auto-execute command and save the configuration.
Example
To configure the Switch to automatically Telnet to device 10.110.100.1 after the
user logs in via VTY 0, enter the following command:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]user-interface vty 0
[4500-ui-vty0]auto-execute command telnet 10.110.100.1

command-privilege level

Syntax
command-privilege level level view view command
undo command-privilege view view command

View
System View
Parameter
level: Enter the command level you want to assign to this command, ranging
from 0 to 3.
view: Enter the name of the view that contains the command. This can be any of

the views supported by the Switch.
command: Enter the command to be configured.

CHAPTER 1: USING SYSTEM ACCESS COMMANDS

Description
Use the command-privilege level command to configure the priority level
assigned to any command within a selected view.
The command levels are, from lowest to highest:
■

0 – Visit

■

1 – Monitoring

■

2 – System

■

3 – Management

When the user logs into the Switch, the commands used depends on the user level
settings and the command level settings on the user interface. The two types of
settings may differ as follows:
■

If AAA/RADIUS authentication is used, the commands the user can access are
determined by the user level settings. For example, if a user is set to level 3 and
the command level on the VTY 0 user interface is level 1, the user can only user
the commands of level 3 or lower when logging into the Switch from the VTY
interface.

■

If RSA public key authentication is used, the commands the user can access are
determined by the command level settings on the user interface.

By default:
■

ping, tracert, and telnet are at level 0

■

display and debugging are at level 1

■

all configuration commands are at system level 2

■

FTP, XMODEM, TFTP and commands for file system operations are at level 3

Use the undo command-privilege view command to restore the default priority
to a command.
Example
To configure the precedence of the command ‘interface’ as 0, enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]command-privilege level 0 view system interface

header

Syntax
header { shell | incoming | login } text
undo header { shell | incoming | login }

View
System view
Parameter
login: Login information in case of authentication. It is displayed before the user

is prompted to enter user name and password.
shell: User conversation established header, the information output after user

conversation has been established. If authentication is required, it is prompted
after the user passes authentication.
incoming: Login header, the information output after a Modem user logs in. If
authentication is required, it is prompted after the user passes authentication. In
this case, no shell information is output.

text: Specifies the title text. If you do not choose any keyword in the command,
the system displays the login information by default. The system supports two
types of input mode: you can input all the text in one line (a maximum of 256
characters, including command key word, can be entered); or you can input all the
text in several lines using the key, and more than 256 characters can be
entered. The text starts and ends with the first character. After entering the last
character, press the key to exit the interactive process.
Description
Use the header command to configure the system to display a header during user
log in. Use the undo header { shell | incoming | login } command to
delete the specified header.
When the user logs in, and a connection is activated, the login header displays.
After the user successfully logs in, the shell header displays.
The first characters in the text are regarded as the start and stop characters. After
you type in the stop character, the system will exit the header command
automatically.
If you do not want to use the control characters, you can type in text with the
same characters at the beginning and end, and press Enter.

CHAPTER 1: USING SYSTEM ACCESS COMMANDS

If you press after typing any of the three keywords shell, login and
incoming in the command, then what you type after the word header is the
contents of the login information, instead of identifying header type.
You can judge whether the initial character can be used as the header contents
this way:
1 If there is only one character in the first line and it is used as the identifier, this
initial character pairs with the ending character and is not the header contents.
2 If there are many characters in the first line but the initial and ending characters
are different, this initial character pairs with the ending character and is the
header contents.
3 There are many characters in the first line and the initial character is identical with
the ending character, this initial character is not the header contents.
Example
Configure the header of setting up a session.
Mode 1: Input in one line
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]header shell %SHELL: Hello! Welcome%

The starting and ending characters must be the same, and press the key
to finish a line.
■

When you log on the Switch again, the terminal displays the configured session
establishment title.

[4500]quit
<4500>quit
Please press ENTER
SHELL: Hello! Welcome

The initial character "%" is not the header contents.
<4500>

Mode 2: Input in several lines
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]header shell % SHELL:

After you pressing the key, the system prompts the following message:
Input banner text, and quit with the character '%'.

Go on inputting the rest text and end your input with the first letter:
Hello! Welcome %

Press the key.
[4500]

Logging in Commands

When you log on the Switch again, the terminal displays the configured session
establishment title.

To ensure that only an authorized user can access the higher level, use the super
password command to set a password for the higher level. If the user does not
enter a valid password, the user level does not change.
Login users are classified into four levels that correspond to the four command
levels. A user can only use commands at the levels that are equal to or lower than
their user level.
Related commands: super password, quit.
Example
To change to user level 3 from the current user level.
<4500>super 3
Password:

The password prompt displays only if you set a password using the super
password command.

Logging in Commands

super password

Syntax
super password [ level level ]{ simple | cipher } password
undo super password [ level level ]

View
System View
Parameter
level: Enter a user level in the range 1 to 3. The default is 3. The password you

enter is set for the specified level.
cipher: Configure to display the password in encrypted text.
simple: Configure to display the password in plain text.
password: If the authentication is in the simple mode, the password must be in
plain text. If the authentication is in the cipher mode, the password can be either

in encrypted text or in plain text. If a plain text password is entered when cipher
mode has been selected, the password will be displayed in the configuration
settings as encrypted. A plain text password is a sequential character string of no
more than 16 digits, for example, 3Com918. The length of an encrypted password
must be 24 digits and in encrypted text, for example,
_(TT8F]Y\5SQ=^Q`MAF4<1!!.
Description
Use the super password command to configure the password for changing the
user from a lower level to a higher level. To prevent unauthorized users from illegal
intrusion, user ID authentication is performed when users switch from a lower
level to a higher level. For the sake of confidentiality, on the screen the user cannot
see the password that he entered. The user has three chances to input valid
password, and then switch to the higher level. Otherwise, the original user level
will remain unchanged. Use the undo super password command to cancel the
password settings.
The password in plain text is required when performing authentication, regardless
of whether the configuration is plain text or encrypted text.
Example
To set the password for level 3 to zbr, type the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]super password level 3 simple zbr

interface_name | aggregation-group agg-id } destination {
interface_list [ aggregation-group agg-id ] | aggregation-group
agg-id }

View
System View
Parameter
interface_type: Source port type.
interface_num: Source port number.
interface_name: Source port name, in the format of interface_name =

interface_type interface_num. For more information, see the parameter item for
the interface command.
interface_list: Destination port list, interface_list1 = { interface_type
interface_num | interface_name } [ to { interface_type interface_num |
interface_name } ] &<1-10>. &<1-10> indicates that the former parameter can

be input 10 times repeatedly at most.
agg-id: Source or destination aggregation group ID. If it is a source aggregation
group, the port with minimum port number is the source port; if it is a destination
aggregation group, the configurations of all its member ports change to be
consistent with that of the source.

Description

broadcast-suppression

Syntax
broadcast-suppression { ratio | pps pps }

CHAPTER 2: USING PORT COMMANDS

undo broadcast-suppression

View
Ethernet Port View
Parameter
ratio: Specifies the bandwidth ratio of broadcast traffic allowed on an Ethernet

port. The ratio value ranges from 1 to 100. The incremental step is 1. By default,
the ratio is 100 meaning all broadcast traffic is accepted. The smaller the ratio is,
the less bandwidth is allocated to broadcast traffic and therefore less broadcast
traffic is accepted on the Ethernet port.
pps pps: Specifies the maximum number of broadcast packets per second
accepted on an Ethernet port. Ranges from 1 to 148810 pps.

Description
Use broadcast-suppression to configure the amount of broadcast traffic that
will be accepted on a port. Once the broadcast traffic exceeds the value set by the
user, the excess broadcast traffic will be discarded. This feature can be used to
ensure network service and prevent broadcast storms.
Example
Enable a limit of 20% of the available bandwidth on a port to be allocated to
broadcast traffic. Broadcast traffic exceeding 20% of the ports bandwidth will be
discarded.

multicast-suppression

Syntax
multicast-suppression { ratio | pps pps}
undo multicast-suppression

View
Ethernet Port View
Parameter
ratio: Specifies the bandwidth ratio of multicast traffic allowed on an Ethernet

port. The ratio value ranges from 1 to 100. The incremental step is 1. By default,
the ratio is 100 meaning all multicast traffic is accepted. The smaller the ratio is,
the less bandwidth is allocated to multicast traffic and therefore less broadcast
traffic is accepted on the Ethernet port.
pps pps: Specifies the maximum number of multicast packets per second accepted

on an Ethernet port. Ranges from 1 to 148810 pps.
Description
Use multicast-suppression to configure the amount of multicast traffic that will
be accepted on a port. Once the multicast traffic exceeds the value set by the user,
the excess multicast traffic will be discarded. This feature can be used to ensure
network service and prevent multicast storms.
Example
Enable a limit of 20% of the available bandwidth on a port to be allocated to
multicast traffic. Multicast traffic exceeding 20% of the ports bandwidth will be
discarded.

Description
Use the port hybrid pvid vlan command to configure the default VLAN ID of
the hybrid port. Use the undo port hybrid pvid command to restore the default
VLAN ID of the hybrid port.
Hybrid port can be configured together with the isolate-user-vlan. But if the
default VLAN has set mapping in the isolate-user-vlan, the default VLAN ID cannot
be modified. If you want to modify it, cancel the mapping first.
The default VLAN ID of local hybrid port must be consistent with that of the peer
one, otherwise, the packets cannot be properly transmitted.
Related command: port link-type.

tie-breaker. For example, 1/0/1 and 2/0/1 are in an aggregation. Port 1/0/1 will be
the master port.
A manual or static aggregation group can have up to eight ports. You can use the
link-aggregation group agg-id mode command to change an existing dynamic
aggregation group into a manual or static one. If the port number in a group
exceeds eight, this operation fails and the system prompts you about the
configuration failure.
Related command: display link-aggregation summary.
Example
To create manual aggregation group 22, enter the following:

Access Management
Configuration
Commands
am enable

This section describes the commands you can use to configure and manage the
Access Management Configuration operations on your Switch 4500.

Syntax
am enable
undo am enable

View
System View
Parameter
none
Description
Use the am enable command to enable the access management function.
Use the undo am enable command to disable the function.
By default, the Access management function is disabled.
When using the access management function, It is recommended that you cancel
the static ARP configuration to ensure that the binding of the IP address and
Ethernet switch takes effect. If you have configured the static ARP for an IP
address in the current port IP address pool from another port, the system will
prompt you to cancel the static ARP setting.
Example
To enable the access management function, enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]am enable

am ip-pool

Parameters
all Enter to configure to operate on all the IP addresses (or IP address pools).
ip-pool Enter to configure IP address pool for access management.

Access Management Configuration Commands

115

address-list Enter IP address list in the start_ip_address [ip_address_num
] & < 1-10 > format.
start_ip_address Is the start address of an IP address range in the pool.
ip_address_num: Specifies how many IP addresses following start_ip_address

in the range.
&< 1-10 > means you can specify ten IP address ranges at most.

Description
Use the am ip-pool command to configure the IP address pool for access
management on a port. The packet whose source IP address is in the specified
pool is allowed to be forwarded on Layer 3 via the port of the switch.
Use the undo am ip-pool command to cancel the access management IP pool of
the port.
By default, all the IP address pools for access management on the port are null and
all the packets are permitted through.
Note that if the IP address pool to be configured contains the IP addresses
configured in the static ARP at other ports, then the system prompts you to delete
the static ARP to make the later binding effective.
Example
To configure the access management IP address pool on Ethernet1/0/1 and
permits the addresses from 202.112.66.2 through 202.112.66.20 and the
specified 202.112.65.1 to access the port, enter the following:

Route state description:
ActiveU — The route is selected and is optimum
Blackhole — Blackhole route is similar to Reject route, but it will not
send the ICMP unreachable message to the source end
Delete — The route is deleted
Gateway — Identifies that the route is not an interface route
Hidden — The route exists, but it is unavailable temporarily for some
reasons (e.g., configured policy or interface is Down). Moreover, you
do not wish to delete it. Therefore, you need to hide it, so as to
restore it again later
Holddown — Holddown is one kind of route redistribution policy
adopted by some distance-vector (D-V) routing protocols (e.g., RIP),
through which these routing protocols can avoid the flooding of error
routes and deliver the routing unreachable message accurately. For
example, the RIP redistributes a certain route every a period of time
regardless of whether the actually found routes destined for the same
destination change. For more details, refer to the specific routing
protocols
Int — The route is discovered by interior gateway protocol (IGP)
NoAdvise — The routing protocol does not redistribute NoAdvise
route when it redistributes routes based on the policy
NotInstall — The routing protocol generally selects the route with the
highest precedence from its routing table, then places it in its core
routing table and redistributes it. Although the NotInstall route
cannot be placed in the core routing table, it is possibly that it is
selected and redistributed
Reject — Unlike the normal routes, the Reject route will discard the
packets that select it as their route, and the router will send ICMP
unreachable message to the source end. Reject route is usually used
for the network test
Retain — When the routes from the routing table are deleted, the
routes with Retain flag will not be deleted. Using this function you can
set Retain flag for some static routes, so that they can exist in the core
routing table
Static — The route with Static flag will not be cleared from the
routing table after you save it and reboot the router. Generally, the
static route configured manually in the router belongs to a Static
route
Unicast — Unicast route

Description
Use the display ip routing-table ip_address command to view routing
information for a specific IP address, and you can also choose the type of
information to display. If the destination address, ip_address, has a
corresponding route in natural mask range, this command will display all subnet
routes or only the route best matching the destination address, ip_address, is
displayed. And only the active matching route is displayed.
Use the display ip routing-table ip_address mask command to display the
route that matches the specified IP destination address and subnet mask.
Use the display ip routing-table ip_address longer-match command to
display all destination address routes that match destination IP addresses in natural
mask range.
Use the display ip routing-table ip_address verbose command to display
verbose information about both active and inactive routes.

Meaning

Holddown

The number of holddown routes.
This refers to a route advertising policy that some distance vector routing
protocols (such as RIP) use to avoid expansion of error routes and to improve
the transmission speed and accuracy of unreachable routes. It usually
advertises a static route at an interval, regardless of the changes to dynamic
routes to the same destination. For details, see the specific routing protocol.

Static Route
Configuration
Command

Delete

The number of deleted routes.

Hidden

The number of hidden routes, that is routes not available at present but still
required. They can be hidden for future use.

This section describes the command you can use to configure a static route.

Static Route Configuration Command

delete static-routes all

147

Syntax
delete static-routes all

View
System View
Parameter
None
Description
Use the delete static-routes all command to delete all the static routes.
The system requests your confirmation before it deletes all the configured static
routes.
Related commands: ip route-static and display ip routing-table.
Example
Delete all the static routes in the router.
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]delete static-routes all
Are you sure to delete all the unicast static routes?[Y/N]

ip route-static

Syntax
ip route-static ip_address { mask | mask-length } { interface_name |
gateway_address } [ preference preference_value ] [ reject |
blackhole ]
undo ip route-static ip_address { mask | mask_length } [
interface_name | gateway_address ] [ preference preference_value ] [
reject | blackhole ]

View
System view
Parameters
ip_address Enter the destination IP address in dotted decimal notation.
mask Enter the IP subnet mask.
mask-length Enter the number of consecutive 1s in the mask. Because 1s in the

32-bit mask must be consecutive, the mask in dotted decimal format can be
replaced by mask-length.
interface_name Specify the transmission interface name of the route. Packets
that are sent to a NULL interface, are discarded immediately which decreases the
system load.
gateway_address Specify the next hop IP address of the route.

148

CHAPTER 6: USING ROUTING PROTOCOL COMMANDS

preference_value Enter the preference level of the route in the range 1 to 255.

The default preference is 60.
reject Enter to indicate an unreachable route.
blackhole Enter to indicate a blackhole route.

Description
Use the ip route-static command to configure a static route.
Use the undo ip route-static command to delete the configured static route.
By default, the system can access the subnet route directly connected to the
router. If you do not use the parameters preference, reject or blackhole, the
route will be reachable by default with a preference level of 60.
A static route is a special route. You can set up an interconnecting network with a
static route configuration. The problem for such configuration is when a fault
occurs to the network, the static route cannot change automatically to steer away
from the node causing the fault without the help of an administrator.
In a relatively simple network, a system administrator may chose to implement
static routes rather than a dynamic routing protocol. The proper configuration and
usage of static routes can improve the network performance and ensure
bandwidth for important applications.
All the following routes are static routes:
■

Reachable route — A normal route. That is, the IP packet is sent to the next
hop via the route marked by the destination. It is the most common type of
static route.

■

Unreachable route — When a static route to a destination has the "reject"
attribute, all the IP packets to this destination will be discarded, and the
originating host will be informed destination unreachable.

■

Blackhole route — If a static route to a destination has the "blackhole"
attribute, the outgoing interface of this route is the Null 0 interface regardless
of the next hop address, and all the IP packets addressed to this destination are
dropped without notifying the source host.

The attributes reject and blackhole are usually used to control the range of
reachable destinations of this router and to help troubleshoot the network.
Use the following precautions when configuring a static route:
■

You cannot specify an interface address of the local Switch as the next hop
address of a static route.

■

When the destination IP address and subnet mask are both set to 0.0.0.0, this
is the configured default route. A packet is forwarded using the default route
as a last resort if no better routing match is found in the routing table.

■

As an alternative way to configure preference level, a flexible routing protocol
can be adopted.

Related command: display ip routing-table, delete static-routes all.

RIP Configuration
Commands

This section describes the commands you can use to configure the Routing
Information Protocol (RIP).
When the Switch 4500 runs a routing protocol, it is able to perform the functions
of a router. The term router in this section can refer either to a physical router or to
the Switch 4500 running a routing protocol.

checkzero

Syntax
checkzero
undo checkzero

View
RIP view
Parameter
None
Description
Use the checkzero command to check the zero field of RIP-1 packets. By default,
RIP-1 performs zero field checking.
Use the undo checkzero command to disable the checking of the zero fields.
According to the RFC1058 protocol specifications, some fields in RIP-1 packets
must be set to zero. These are called zero fields. During the zero check operation,
if a RIP-1 packet is received in which the zero fields are not zeros, it will be
rejected. Use the checkzero command to enable or disable the zero check
operation on RIP-1.
This command does not work with RIP-2 packets, since RIP-2 packets have no zero
fields.
Example
To configure the Switch not to perform zero checking for RIP-1 packet, enter the
following:
<4500>system-view
System View: return to User View with Ctrl+Z.

CHAPTER 6: USING ROUTING PROTOCOL COMMANDS

Parameters
protocol Enter the routing protocol to be imported. This can be one of the
following: direct or static.
value Enter the cost value of the route to be imported.
route-policy route_policy_name Enter a route-policy name. Only routes that
match the conditions of the specified policy are imported.

Description
Use the import-route command to import the routes of other protocols into RIP.
Use the undo import-route command to cancel the import of routes from other
protocols. By default, RIP does not import any other protocol’s route.
The import-route command can be used to import the route of another protocol
with a certain cost value. RIP regards the imported route as its own route and
transmits it with the specified cost value. This command can greatly enhance the
RIP capability of obtaining routes, thus increases the RIP performance.
If the cost value is not specified, routes will be imported according to the
default cost ranging from 1 to 16. If the imported route cost value is 16, then
RIP continues to announce this cost to other routers running RIP, and marks this
route with HOLDDOWN. However, this router can still forward packets until the
Garbage Collection timer times out (defaults to 120 seconds).
Related commands: default cost.
Example
To import a static route with a cost of 4, enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]rip
[4500-rip]import-route static cost 4

network

Syntax
network network_address
undo network network_address

View
RIP view
Parameter
network_address Enter the IP network address of an interface.

Description
Use the network command to enable Routing Information Protocol (RIP) on the
interface of a specified network segment connected to the router.

RIP Configuration Commands

155

Use the undo network command to disable RIP on the interface. By default, RIP is
disabled on an interface.
After you have enabled RIP, you must also enable RIP for a specified interface using
this command. RIP only operates on the interface of specified network segments.
The undo network command is similar to the undo rip work command in the
VLAN Interface View, in that an interface using either command will result in the
interface not receiving/transmitting RIP routes. However, if you use undo rip
work, other interfaces will still forward the routes of the interfaces set to undo rip
work. If you use undo network, other interfaces will not forward the routes of
interfaces set to undo network.
When the network command is used on an IP address, the interface on this
network segment is enabled. For example, if you view the network 129.102.1.1
with both the display current-configuration command and the display
rip, the IP address is shown as 129.102.0.0.
Related commands: rip work.
Example
To enable RIP on the interface with the network address 129.102.0.1, enter the
following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]rip

Parameter
ip_address Enter the interface IP address of the peer router.

Description
Use the peer command to configure the destination address of the peer device.
Use the undo peer command to cancel the set destination address. By default,
there is no destination address.
3Com recommends that you do not use this command. RIP can use unicast to
exchange information with non-broadcasting networks. If required, you can use
this command to specify the destination address of the peer device.
Example
To specify the sending destination address as 202.38.165.1, enter the following:
<4500>system-view

100.
Description
Use the preference command to configure the route preference of RIP.
Use the undo preference command to restore the default preference.
The default value of each routing protocol is determined by the specific routing
policy. This “preference” determines the optimal route in the IP routing table. You
can use this command to modify the RIP preference.

to 3600 seconds. The default value is 30 seconds.
timeout-timer-length Enter the value of the timeout timer, ranging from 1 to
3600 seconds. The default value is 180 seconds.

Description
Use the timers command to modify the values of the three RIP timers: period
update, timeout, and garbage-collection.
Use the undo timers command to restore the default settings.
By default, the values of period update, timeout, and garbage-collection timers
are 30 seconds, 180 seconds, and 120 seconds, respectively.
Generally, the value of the garbage-collection timer is fixed to 4 times the value of
the period update timer. Adjusting the period update timer will affect the
garbage-collection timer.
The modification of RIP timers takes effect immediately.

permit Enter to specify the match mode of the defined address prefix list items as

permit mode.
deny Enter to specify the match mode of the defined address prefix list items as
deny mode.
network Enter the IP address prefix range (IP address). If it is 0.0.0.0 0, all the IP
addresses are matched.
len Enter the IP address prefix range (mask length). If it is 0.0.0.0 0, all the IP

addresses are matched.
greater_equal, less_equal The address prefix range [greater-equal, less-equal]
to be matched after the address prefix network len has been matched. The
meaning of greater-equal is "larger than or equal to" , and the meaning of
less-equal is "less than or equal to". The range is len <= greater-equal <=
less-equal <= 32. When only greater-equal is used, it denotes the prefix range
[greater-equal, 32]. When only less-equal is used, it denotes the prefix range
[len, less-equal].

Description
Use the ip ip-prefix command to configure an address prefix list or one of its
items.
Use the undo ip ip-prefix command to delete an address prefix list or one of its
items.
By default, there’s no address prefix list.
The address prefix list is used for IP address filtering. An address prefix list may
contain several items, and each item specifies one address prefix range. The
inter-item filtering relation is "OR", i.e. passing an item means passing the filtering
of this address prefix list. Not passing the filtering of any item means not passing
the filtration of this prefix address list.
The address prefix range may contain two parts, which are determined by len and
[greater-equal, less-equal] respectively. If the prefix ranges of these two parts
are both specified, the IP to be filtered must match the prefix ranges of these two
parts.
If you specify network len as 0.0.0.0 0, it only matches the default route.
Example
The prefix address list of this address indicates to match the bits 1 to 8 and the bits
17 to 18 for filtering the IP address with the bits 1 to 8 and the bits 17 to 18 of the
specified IP network segment 10.0.192.0.

Description
Use the route-policy command to create and enter the Route-policy view.
Use the undo route-policy command to delete the established Route-policy.
By default, no Route-policy is defined.
The route-policy command is used for route information filtration or route
policy. One Route-policy comprises some nodes and each node comprises some
match and apply sub-statements. The match sub-statement defines the match
rules of this node and the apply sub-statement defines the actions after passing
the filtration of this node. The filtering relationship between the match
sub-statements of the node is “and”, that is, all match sub-statements that meet
the node. The filtering relation between Route-policy nodes is "OR", i.e. passing
the filtering of one node means passing the filtering of this Route-policy. If the
information does not pass the filtration of any nodes, it cannot pass the filtration
of this Route-policy.
Related commands: if-match interface, if-match acl, if-match ip-prefix,
if-match ip next-hop, if-match cost, apply cost.
Example
Configured one Route-policy policy1, whose node number is 10 and if-match

acl

Syntax
acl acl-number1 { inbound | outbound }
undo acl acl-number1 { inbound | outbound }
acl acl-number2 inbound
undo acl acl-number2 inbound

View
User interface view

Parameter
acl-number1: Number of number-based basic and advanced ACLs, in the
range of 2,000 to 3,999.
acl-number2: Number of number-based L2 ACLs, in the range of 4,000 to
4,999.
inbound: Implements ACL control over the users logging into local
switch in the TELNET or SSH mode.
outbound: Implements ACL control over the users logging into other
switches from local switch in the TELNET or SSH mode.

Description
Use the acl command to use ACLs, implementing ACL control over TELNET or SSH
users.
Use the undo acl command to cancel the ACL control over TELNET or SSH users.
■

You can only use number-based ACLs for TELNET or SSH user ACL control.

■

When TELNET or SSH users use basic or advanced ACLs, the incoming/outgoing
calls are restricted on the basis of the source or destination IP address. As a
result, when you use the rules for basic and advanced ACLs, only the source IP
and the corresponding mask, the destination IP and the corresponding mask,
and the time-range keyword take effect. When TELNET and SSH users use L2
ACLs, the incoming/outgoing calls are restricted on the basis of source MAC
addresses. As a result, when you use the rules for L2 ACLs, only the source
MAC and the corresponding mask, and the time-range keyword take effect.

■

When you control telnet and SSH users on the basis of L2 ACLs, only the
incoming calls are restricted.

■

If a user is refused to log in due to ACL restriction, the system will record the
log information about an access failure. The log information includes the user
IP address, login mode, index value for a login user interface and reason for
login failure.

By default, the incoming/outgoing calls of the user interface are not restricted.

View
Corresponding ACL View
Parameter
rule-id: Specifies the subitems of an ACL, ranging from 0 to 65534.
permit: Permits packets that meet the requirements.
deny: Denies packets that meet the requirements.

The following parameters are various property parameters carried by packets. The
ACL sets rules according to this parameter.
Parameters specific to basic ACLs:
source { source-addr wildcard | any }: source-addr wildcard represents

the source IP address and the wildcard digit represented in dotted decimal
notation. any represents all source addresses.
fragment: Means this rule is only effective fragment packets and is ignored for

non-fragment packets.
Parameters specific to advanced ACLs:
protocol: Specifies the protocol type which is represented by a name or a
number. When it is a name, this parameter can be adopted like: icmp, igmp, tcp,
udp, ip, gre, ospf, ipinip, etc. If the adopted value is IP, that means all the Internet
Protocols. When it is a number: it ranges from 1 to 225.
source { source-addr wildcard | any }: source-addr wildcard means the
source IP address and the wildcard digit represented in dotted decimal notation.
any means all source addresses.
destination { dest-addr wildcard | any }: dest-addr wildcard means the

destination IP address and the wildcard digit represented in dotted decimal
notation. any means all destination addresses.
source-port operator port1 [port2]: Source port number of TCP or UDP used
by the packet. operator is port operator, including eq (equal), gt (greater than), lt
(less than),neq (not-equal), range (within this range). Note that this parameter is
only available when the parameter protocol is TCP or UDP. port1 [port2]: Source
port number of TCP or UDP used by the packet, notated by a character or a
number which ranges from 0 to 65535 inclusive. For the value of the character,
please refer to mnemonic symbol table. The two parameters port1 and port2
appear at the same time only when the operator is “range”, but other operators
need “port1” only.
destination-port operator port1 [port2]: Destination port number of TCP or
UDP used by packets. For detailed description, please refer to source-port
operator port1 [port2].
icmp-type type code: Appears when protocol is icmp. type code specifies an
ICMP packet. type represents the type of ICMP packet, notated by a character or

ACL Commands List

189

a number which ranges from 0 to 255; code represents ICMP code, which appears
when the protocol is “icmp” and the type of packet is not notated by a character,
ranging from 0 to 255.
established: Means that it is only effective to the first SYN packet established by

TCP, appears when protocol is TCP.
precedence precedence: IP precedence, can be a name or a number ranging from

0 to 7.
tos tos: ToS (Type of Service) value, can be a name or a number ranging from 0 to

15. Packets can be classified according to TOS value.
dscp dscp: DSCP (Differentiated Services Code Point) value, can be a name or a

number ranging from 0 to 63. Packets can be classified according to DSCP value.
fragment: Means this rule is only effective for fragment packets and is ignored for
non-fragment packets.

Parameters specific to Layer 2 ACL:
| source-mac-addr source-mac-wildcard }*: The
source information of a packet, source-vlan-id represents source VLAN of the
packet, source-mac-addr source-mac-wildcard represents source MAC address
of the packet. For example, if you set source-mac-wildcard to 0-0-ffff, it means
that you will take the last 16 bits of source MAC address as the rule of traffic
classification.
source { source-vlan-id

dest { dest-vlan-id | dest-mac-addr dest-mac-wildcard }*: The
destination information of a packet: dest-mac-addr dest-mac-wildcard
represents the packet’s destination MAC address. For example, if you set
source-mac-wildcard to 0-0-ffff, it means that you will take the last 16 bits of
source MAC address as the rule of traffic classification.
type protocol-type protocol-type-mask: Protocol type carried by the Ethernet

frame.
lsap lsap-type lsap-type-mask: lsap type carried by the Ethernet frame.

The parameter for user-defined ACL
{ rule-string rule-mask offset }&<1-8>: rule-string is a character string

of a rule defined by a user ranging from 2 to 80 characters. It is a hexadecimal
string with even digits. rule-mask offset is used to extract the packet
information. Here, rule-mask is rule mask, used for logical AND operation with
data packets, and offset determines to perform AND operation from which bytes
apart from the packet header. rule-mask offset extracts a character string from
the packet and compares it with the user-defined rule-string to get and process
the matched packets. &<1-8> indicates that you can define up to 8 such rules at a
time. This parameter is used for the user-defined ACL.
Description
Use the rule command to add a subrule to an ACL.
Use the undo rule command to cancel a subrule from an ACL.

190

CHAPTER 8: USING QOS/ACL COMMANDS

You can define several subrules for an ACL. If you include parameters when using

CHAPTER 9: USING STACK COMMANDS

change unit-id

Syntax
change unit-id to < 1-8 >{ < 1-8 > | auto-numbering }

View
System View
Parameter
< 1-8 >: Unit ID of the unit in a stack.
auto-numbering: Change the unit ID automatically.

Description
Use the change unit-id command to change the unit ID of a Switch in the stack.
By default, the unit ID of a Switch is set to 1. A unit ID can be set to a value in the
range from 1 to the maximum number of devices supported in the stack.
■

If the modified unit ID does not exist in the stack, the system sets its priority to
5 and saves it in the unit Flash memory.

■

If the modified unit is an existing unit, the system will prompt you to confirm if
you do want to change the unit ID. If you choose to change, the existing unit
ID is replaced and the priority is set to 5. You can then use the fabric
save-unit-id command to save the modified unit ID into the unit Flash
memory and clear the information about the existing unit ID.

■

If auto-numbering is selected, the system sets the unit ID priority to 10. You
can use the fabric save-unit-id command to save the modified unit ID into
the unit Flash memory and clear the information about the existing unit ID.

Example
To change the unit ID from6 to 4, enter the following:

Use the undo stp bpdu-protection command to resume the default status of
BPDU protection function.
By default, BPDU protection is not enabled.
For an access layer device, its ports are generally directly connected to a user
terminal (such as a PC) or file server, and configured as an edge port to implement
fast transition. When such a port receives BPDU packets, the system will set it to a
non-edge port and recalculate the spanning tree, which will cause network
topology flapping. In normal circumstances, these ports should not receive any
BPDU packets. However, someone may forge BPDU to maliciously attack the
Switch and cause network flapping.
RSTP provides the BPDU protection function against such an attack. After the
BPDU protection function is enabled on a Switch, the system will disable an edge
port that has received BPDUs and notify the network manager about it. The
disabled port can only be re-enabled by the network manager.
Example
To enable BPDU protection function on a Switch, enter the following:

Parameter
cost: Specifies the path cost, ranging from 1 to 2000000.

Description
Use the stp cost command to configure the path cost on a spanning tree for the
current Ethernet port.
Use the undo stp cost command to restore the default cost.
By default, the bridge gets the path cost directly through the speed of the link
connected to the port.
The path cost of an Ethernet port is related to the link speed. You can refer to the
following table. RSTP will check the link speed of the port and get the path cost
directly. It is recommended to set the cost to the default value and let RSTP query
the path cost of the port.

Description
Use the stp edged-port enable command to configure the current port as an
edge port.
Use the stp edged-port disable command to configure the current port as a
non-edge port.
Use the undo stp edged-port command to restore the default setting.
By default, all the Ethernet ports of the bridge are configured as non-edge ports.
If the current Ethernet port is connected to other Switch, you can use the stp
edged-port disable or undo stp edged-port command to specify it as a
non-edge port. The stp edged-port enable command can be used to configure the
current Ethernet port as an edge port. All the Ethernet ports have been set to
non-edge ports by default. You can configure the Ethernet ports directly
connected to the user terminals as edge ports, so that they can transition to
forwarding state quickly.

Parameter
None
Description
If the network is unstable, even when the bridge running STP on the segment is
removed, the corresponding port will still work in the STP compatible mode.
Use the stp mcheck command to force the port to work in RSTP mode.
If there is any bridge running STP on the segment connected to the current
Ethernet port, the port will Switch to run RSTP in STP compatible mode. If the
network is rather stable, even when the bridge running STP on the segment is
removed, the corresponding port will still work in the STP compatible mode. In this
case, you can use this command to force the port to work in RSTP mode. In RSTP
mode, when the port receives an STP packet, it will transition to the STP
compatible mode.
The configuration can only be performed when the bridge runs in RSTP mode. If
the bridge is configured to work in STP compatible mode, the command will not
make any sense.
Related command: stp mode.

Description
Use the stp root primary command to configure the current Switch as the
primary root of a spanning tree.
Use the undo stp root command to cancel the current Switch for primary root of
a spanning tree.
By default, the Switch is not a primary root.
You can designate a primary root for the spanning tree without caring about the
priority configuration of the Switch.
CAUTION: In a switching network, you can configure no more than one primary
root for a spanning tree but you can configure one or more secondary roots for it.
Remember not to designate more than one primary root in a spanning tree;
otherwise, the switching behavior will be unpredictable.
After a Switch is configured as a primary root bridge or secondary root bridge, you
can not modify the bridge priority of the Switch.
Example

Use the undo stp root command to cancel the designation of the current Switch
for a secondary root of a specified spanning tree.
By default, a Switch is not a secondary root.
You can designate one or more secondary roots for a spanning tree. When the
primary root fails or is powered off, a secondary root can take its place. If more
than one secondary root exists, the one with the smallest MAC address will
become the primary root of the specified spanning tree.
You can configure no more than one primary root for a spanning tree but you can
configure one or more secondary roots for it. You cannot change the bridge
priority of a Switch if you configure it as a secondary root of a spanning tree.
Example
To designate the Switch as a secondary root of the STP, enter the following:

Parameter
None
Description
Use the stp root-protection command to enable Root protection function on a
Switch.
Use the undo stp root-protection command to restore the default status of
Root protection function.
By default, root protection is not enabled.
Following incorrect configuration or malicious attack, a legal root of the network
may receive a BPDU with higher priority and lose its status as root, which causes
problems with the network topology. Such problems may pull the higher-speed
traffic to lower-speed links and cause network congestion.
To avoid this problem, RSTP provides Root protection function. After being
configured with Root protection, a port always stays as a designated port. Once
this port receives a BPDU with higher priority, it turns to listening status and will

228

CHAPTER 10: USING RSTP COMMANDS

not forward any packets (as if the link to it is disconnected). It will resume normal
status if it receives no BPDU with higher-priority for a period of time.
Example
To enable Root protection function on Ethernet1/0/1 of the Switch, enter the
following:
<4500>system-view
System View: return to User View with Ctrl+Z.

Parameter
number: Specifies the multiple of hello time, ranging from 3 to 7.

Description
Use the stp timeout-factor command to configure the multiple of hello time
for the Switch.
Use the undo stp timeout-factor command to restore the default multiple
value.
By default, the multiple is 3.
The Ethernet Switch transmits RSTP packets every hello time seconds. By default, if
the Switch does not receive RSTP packets from the upstream Switch for 3 x hello
time seconds, the Switch will decide the upstream Switch is dead and will
recalculate the topology of the network. In a congested network, a system
administrator may want to increase the timeout interval to prevent an unnecessary
network topology change. This can be accomplished by using the timeout-factor
command to set the multiplier to the desired value. The higher the multiplier the
greater the timeout interval. It is recommended to set 5, 6 or 7 as the value of
multiple in the steady network.
Example
To set the multiple value of hello time to 7, enter the following:

System View
Parameter
centiseconds: Specifies the time of forward delay in centiseconds, ranging from

400 to 3000. By default, the value is 1500 centiseconds.
Description
Use the stp timer forward-delay command to configure the time of forward
delay for the Switch.
Use the undo stp timer forward-delay command to restore the default
forward delay time.
The value of forward delay is related to the “diameter” of the switching network.
The more extensive the switching network is, the longer the forward delay should
be set. You can use this command to modify the value of forward delay. The
default value, 1500, is recommended.
Related commands: stp timer hello, stp timer max-age.
Example
To set the forward delay of the device to 2000 centiseconds, enter the following:
<4500>system-view

Description
Use the stp timer hello command to configure hello time of the Switch.
Use the undo stp timer hello command to restore the default hello time.
The Ethernet Switch transmits RSTP packets every hello time seconds. A longer
hello time can ease the CPU load of the Switch, but it will also affect the
performances of RSTP in how rapidly it responds to changes. The stp timer
hello command can be used to modify the value of hello time. The default value
is recommended.

Parameter
centiseconds: Specifies the maximum age in centiseconds, ranging from 600 to
4000. By default, the value is 2000 centiseconds.

Description
Use the stp timer max-age command to configure the Max Age of the Switch.
Use the undo stp timer max-age command to restore the default Max Age.
Maximum age is used for judging if an RSTP packet is outdated. If the value is set
too small, the spanning tree will be computed too frequently because the network
congestion may be considered as a link failure. However, if the value is set too
large, the link failure may not be discovered in time. Maximum age is related to
the network “diameter”, or complexity of the switched network. The default
value, 2000, is recommended.
Related commands: stp timer forward-delay, stp timer hello.
Example
To set the Max Age of the Switch to 1000 centiseconds, enter the following:
<4500>system-view

Description
Use the stp transmit-limit command to set the maximum number of STP
packets the current port can send within one hello time.
Use the undo stp transmit-limit command to restore the default value.
The larger the value of packetnum is, the larger the transmission rate is. However,
more Switch resources will be used.
Example
To set the packetnum parameter of Ethernet1/0/1 to 5, enter the following:

Description
Use the dot1x command to enable 802.1x on the specified port or globally, (that is
on the current device). Use the undo dot1x command to disable the 802.1x on
the specified port or globally.
By default, 802.1x is disabled on all the ports and globally on the device.
This command is used to enable the 802.1x on the current device or on the
specified port. When it is used in System View, if the parameter ports-list is not
specified, 802.1x will be globally enabled. If the parameter ports-list is
specified, 802.1x will be enabled on the specified port. When this command is
used in Ethernet Port View, the parameter interface-list cannot be entered and
802.1x can only be enabled on the current port.
The configuration command can be used to configure the global or port 802.1x
performance parameters before or after 802.1x is enabled. Before 802.1x is

Parameter
Chap: Use CHAP authentication method.
Pap: Use PAP authentication method.
eap: Use EAP authentication method.

Description
Use the dot1x authentication-method command to configure the
authentication method for the 802.1x user. Use the undo dot1x
authentication-method command to restore the default authentication method

By default, CHAP authentication is used for 802.1x user authentication.
Password Authentication Protocol (PAP) is a kind of authentication protocol with
two handshakes. It sends the password in the form of simple text.
Challenge Handshake Authentication Protocol (CHAP) is a kind of authentication
protocol with three handshakes. It only transmits the username, not the password.
CHAP is more secure and reliable.
In EAP authentication, a Switch authenticates supplicant systems by encapsulating
802.1x authentication information in EAP packets and sending the packets to the
RADIUS server, instead of converting the packets into RADIUS packets before

namely authenticate the users, on the specified interface. When macbased is used,
the users accessing this interface must be authenticated independently, and as
such will be able to access the network as long as they independently require.
When portbased is used, only the first user on that port needs to be
authenticated. Subsequent users accessing the network through this port are
considered authenticated. However if the original user terminates his connection,
the other users will need to be re-authenticated.
This command has an effect on the interface specified by the parameter

Parameter
handshake-period: This timer begins after the user has passed authentication.

After setting the handshake-period, the system will send a handshake packet
every handshake period seconds. Suppose the dot1x handshake-period time is
configured as N, the system will consider the user as having logged off and will set
the user state as logoff if the system does not receive a response from the user for
N consecutive times.
handshake-period-value: Handshake period. The value ranges from 1 to 1024 in
units of second and defaults to 15.
quiet-period: Specify the quiet timer. If an 802.1x user has not passed the

authentication, the Authenticator will keep quiet for a while (which is specified by
quiet-period timer) before launching the authentication again. During the quiet
period, the Authenticator does not do anything related to 802.1x authentication.
quiet-period-value: Specify how long the quiet period is. The value ranges

from 10 to 120 in units of second and defaults to 60.

supp-timeout: Specify the authentication timeout timer of a Supplicant. After

the Authenticator sends Request/Challenge request packet which requests the
MD5 encrypted text, the supp-timeout timer of the Authenticator begins to run. If
the Supplicant does not respond back successfully within the time range set by
this timer, the Authenticator will resend the above packet.
supp-timeout-value: Specify how long the duration of an authentication
timeout timer of a Supplicant is. The value ranges from 10 to 120 seconds and
defaults to 30 seconds.
tx-period: Specify the transmission timeout timer. After the Authenticator sends

the Request/Identity request packet which requests the user name or user name
and password together, timer of the Authenticator begins to run. If the Supplicant
does not respond back with authentication reply packet successfully, then the
Authenticator will resend the authentication request packet.
tx-period-value: Specify how long the duration of the transmission timeout

timer is. The value ranges from 10 to 120 seconds and defaults to 30 seconds.

ISP domain where the users are located.) The argument minute defines the
idle-cut time, which is in the range of 60 to 7200 seconds.
access-limit max-user-number: Specifies the maximum number of users who
access the device using the current user name. The argument max-user-number is

in the range of 1 to 1024.
vlan vlanid: Sets the VLAN attribute of user, in other words, the VLAN to which
a user belongs. The argument vlanid is an integer in the range of 1 to 4094.
location: Sets the port binding attribute of user.
nas-ip ip-address: The IP address of the access server in the event of binding a
remote port with a user. The argument ip-address is an IP address in dotted
decimal format and defaults to 127.0.0.1.
port portnum: Sets the port to which a user is bound. The argument portnum is

represented by “SlotNumber SubSlotNumber PortNumber”. If any of these three
items is absent, the value 0 will be used to replace it.
Description
Use the attribute command to configure some attributes for specified local user.
Use the undo attribute command to cancel the attributes that have been
defined for this local user.
It should be noted that the argument nas-ip must be defined for a user bound
with a remote port, which is unnecessary, however, in the event of a user bound
with a local port.
Related command: display local-user.

System View
Parameter
isp-name: Specifies an ISP domain name. The name is expressed with a character
string not exceeding 24 characters, excluding “/”, “: ”, “*”, “? ”, “<”, and “>”.
default enable isp-name: Enables the default ISP domain specified by
isp-name.
default disable: Restores the default ISP domain to system.

Description
Use the domain command to configure an ISP domain or enter the view of an
existing ISP domain. Use the undo domain command to cancel a specified ISP
domain.
By default, a domain named system has been created in the system. The
attributes of system are all default values.
ISP domain is a group of users belonging to the same ISP. Generally, for a
username in the userid@isp-name format, taking gw20010608@3Com163.net as an
example, the isp-name (that is, 3Com163.net) following the @ is the ISP domain
name. When 3Com 4500 Series Ethernet Switches control user access, as for an
ISP user whose username is in userid@isp-name format, the system will take
userid part as username for identification and take isp-name part as domain
name.
The purpose of introducing ISP domain settings is to support the application
environment with several ISP domains. In this case, an access device may have
supplicants from different ISP domains. Because the attributes of ISP users, such as
username and password structures, service types, may be different, it is necessary
to separate them by setting ISP domains. In ISP Domain View, you can configure a
complete set of exclusive ISP domain attributes for each ISP domain, which
includes AAA schemes ( RADIUS scheme applied and so forth.)

AAA and RADIUS Configuration Commands

261

For a Switch, each supplicant belongs to an ISP domain. The system supports up to
16 ISP domains. If a user has not reported its ISP domain name, the system will
put it into the default domain.
When this command is used, if the specified ISP domain does not exist, the system
will create a new ISP domain. All the ISP domains are in the active state when
they are created.
Related commands: access-limit, radius scheme, state, display domain.
Example
To create a new ISP domain, marlboro.net, and enters its view, enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]domain marlboro.net

idle-cut

Syntax
idle-cut { disable | enable minute flow }

View
ISP Domain View
Parameter
disable: means disabling the user to use idle-cut function .
enable: means enabling the user to use the function.
minute: Specifies the maximum idle time, ranging from 1 to 120 and measured in

minutes.
flow: The minimum data traffic, ranging from 1 to 10,240,000 and measured in

bytes.
Description
Use the idle-cut command to configure the user template in the current ISP
domain.
By default, after an ISP domain is created, this attribute in user template is
disable, that is, the user idle-cut is disabled.
The user template is a set of default user attributes. If a user requesting for the
network service does not have some required attributes, the corresponding
attributes in the template will be endeavored to him as default ones. The user
template of the Switch you are using may only provide user idle-cut settings. After
a user is authenticated, if the idle-cut is configured to enable or disable by neither
the user nor the RADIUS server, the user will adopt the idle-cut state in the
template.
Because a user template only works in one ISP domain, it is necessary to configure
user template attributes for users from different ISP domain respectively.

262

CHAPTER 11: USING AAA AND RADIUS COMMANDS

Related command: domain
Example
To enable the user in the current ISP domain, 3Com163.net, to use the idle-cut

By default, the user priority level is 0.
Related command: local-user
If the configured authentication mode is none authentication or password
authentication, the command level that a user can access after login depends on
the priority of user interface. In the case of authentication requiring both
username and password, however, the accessible command level depends on user
priority level.
Example
To set the priority level of the user 3Com to 3, enter the following:

Parameter
limit: Remaining-online-time threshold in minutes, in the range of 1 to 60. When

the remaining online time of a user is equal to this threshold, the Switch begins to
send alert messages to the client.
interval: Sending interval of alert messages in minutes, in the range of 5 to 60
(must be a multiple of 5).

Description
Use the messenger time enable command to enable messenger alert and
configure the related parameters.
Use the messenger time disable command to disable messenger alert.
Use the undo messenger time command to restore messenger alert to default
settings.
By default, the messenger alert is disabled on the Switch.
This function allows the clients to inform the online users about their remaining
online time through message alert dialog box.
The implementation of this function is as follows:
■

On the Switch, use the messenger time enable command to enable this
function and to configure the remaining-online-time threshold (the limit
argument) and the alert message interval.

■

If the threshold is reached, the Switch sends messages containing the user's
remaining online time to the client at the interval you configured.

View
ISP Domain View
Parameter
radius-scheme-name: RADIUS scheme, a character string not exceeding 32

characters.
local: Local authentication.
none: No authentication.

Description
Use the scheme command to configure the AAA scheme to be referenced by the
current ISP domain. Use the undo scheme command to restore the default AAA
scheme.
The default AAA scheme in the system is local.
The system adopts three types of AAA schemes to perform authentication and/or
accounting: local authentication, no authentication and RADIUS scheme.
■

When using radius-scheme radius-scheme-name local in the configuration
command, the local refers to the alternative authentication scheme if the
RADIUS server does not respond normally. Therefore, when the RADIUS server
operates normally, the local scheme is not used otherwise, the local scheme is
used.

AAA and RADIUS Configuration Commands

■

If the local or none scheme applies, no RADIUS scheme can be adopted.

■

If you want to specify the ISP domain to adopt RADIUS scheme, then the
RADIUS scheme must have already been configured.

267

You can use either scheme or radius-scheme command to specify the RADIUS
scheme for an ISP domain. If both of these two commands are used, the latest
configuration will take effect.
Related command: radius scheme, display radius
Example
To specify the current ISP domain, 3Com163.net, to use the RADIUS scheme
3Com, enter the following:

Parameter
url-string: The URL address of the page used to change the user password on

the self-service server, a string with 1 to 64 characters. This string cannot contain
"?" character. If "?" is contained in the URL address, you must replace it with "|"
when inputting the URL address in the command line.
Description
Use the self-service-url enable command to configure self-service server
URL.
Use the self-service-url disable command to remove the configuration.
By default, self-service server URL is not configured on the Switch.
This command must be incorporated with a RADIUS server (such as a CAMS
server) that supports self-service. Self-service means that users can manage their
accounts and card numbers by themselves. And a server with the self-service
software is called a self-service server.
Once this function is enabled on the Switch, users can locate the self-service server
and perform self-management through the following operations:
■

Select "Change user password" on the 802.1x client.

■

After the client opens the default explorer (IE or NetScape), locate the specified
URL page used to change the user password on the self-service server.

■

Change user password on this page.

268

CHAPTER 11: USING AAA AND RADIUS COMMANDS

The "Change user password" option is available only after the user passed the
authentication; otherwise, this option is in grey and unavailable.

Parameter
accounting: Configures to set/delete the authentication key for the RADIUS

accounting packet.
authentication: Configures to set/delete the encryption key for RADIUS
authentication/authorization packet.
string: Specifies the key with a character string not exceeding 16 characters. By
default, the key is “3Com”.

Description
Use the key command to configure encryption key for RADIUS
authentication/authorization or accounting packet. Use the undo key command
to restore the default key.
RADIUS client (Switch) and RADIUS server use MD5 algorithm to hash the
exchanged packets. The two ends verify the packet through setting the key. Only
when the keys are identical can both ends accept the packets from each other and
give responses. So it is necessary to ensure that the keys set on the Switch and the
RADIUS server are identical. If the authentication/authorization and accounting are
performed on two different servers with different keys, you should set two keys
respectively.

Parameter
retry-times: Specifies the maximum times of retransmission, ranging from 1 to

20. By default, the value is 3.
Description
Use the retry command to configure the RADIUS request retransmission times.
Use the undo retry command to restore the retry-times to default value.
Because RADIUS protocol uses UDP packets to carry the data, its communication
process is not reliable. If the RADIUS server has not responded NAS until timeout,
NAS has to retransmit RADIUS request packet. If it transmits more than the
specified retry-time, NAS considers that the communication with the current
RADIUS server has been disconnected and it will transmit request packet to other
RADIUS servers.
Setting a suitable retry-time according to the network situation can speed up the
system response.
Related command: radius scheme
Example
To set to retransmit the RADIUS request packet no more than 5 times via the server
3Com in the RADIUS scheme, enter the following:

Parameter
retry-times: Specifies the maximum times of real-time accounting request

failing to be responded, ranging from 1 to 255. By default, the accounting request
can fail to be responded up to 5 times.
Description
Use the retry realtime-accounting command to configure the maximum
number of retries for real-time accounting requests. Use the undo retry
realtime-accounting command to restore the maximum number of retries for
real-time accounting requests to the default value.
RADIUS server usually checks if a user is online with timeout timer. If the RADIUS
server has not received the real-time accounting packet from NAS, it will consider
that there is line or device failure and stop accounting. Therefore, it is necessary to
disconnect the user at the NAS end and on the RADIUS server synchronously when
unexpected failure occurs. The Switch 4500 Series supports a maximum number
of times that real-time accounting requests can fail to be responded to. NAS will
disconnect the user if it has not received a real-time accounting response from the
RADIUS server for the number of specified times.
How is the value of count calculated? Suppose RADIUS server connection will
timeout in T and the real-time accounting interval of NAS is t, then the integer
part of the result from dividing T by t is the value of count. Therefore, when
applied, T is suggested the numbers which can be divided exactly by t.
Related command: radius scheme.
Example
To allow the real-time accounting request failing to be responded for up to 10
times, enter the following:

Description
Use the retry stop-accounting command to configure the maximal
retransmission times after stopping accounting request. Use the undo retry
stop-accounting command to restore the retransmission times to the default
value.
Because the stopping accounting request concerns account balance and will affect
the amount of charge, which is very important for both the user and ISP, NAS shall
make its best effort to send the message to RADIUS accounting server.
Accordingly, if the message from the Switch to RADIUS accounting server has not
been responded, the Switch shall save it in the local buffer and retransmit it until
the server responds or discard the messages after transmitting for specified times.
Related commands: reset stop-accounting-buffer, radius scheme, display

accounting: Configures to set the state of RADIUS accounting server.

RADIUS Protocol Configuration Commands

287

authentication: Configures to set the state of RADIUS
authentication/authorization.
block: Configures the RADIUS server to be in the state of block.
active: Configures the RADIUS server to be active, namely the normal

operation state.
Description
Use the state command to configure the state of RADIUS server.
By default, as for the newly created RADIUS scheme, the primary and secondary
accounting/authentication servers are in the state of block; as for the "system"
RADIUS scheme created by the system, the primary accounting/authentication
servers are in the state of active, and the secondary accounting/authentication
servers are in the state of block.
For the primary and second servers (no matter an authentication/authorization or
an accounting server), if the primary server is disconnected to NAS for some fault,
NAS will automatically turn to exchange packets with the second server. However,
after the primary one recovers, NAS will not resume the communication with it at
once, instead, it continues communicating with the second one. When the second
one fails to communicate, NAS will turn to the primary one again. This command
is used to set the primary server to be active manually, in order that NAS can
communicate with it right after the troubleshooting.
When the primary and second servers are all active or block, NAS will send the
packets to the primary server only.
Related commands: radius scheme, primary authentication, secondary
authentication, primary accounting, secondary accounting.
Example
To set the second authentication server of RADIUS scheme, “3Com”, to be active,
enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]radius scheme 3Com
[4500-radius-3Com]state secondary authentication active

CHAPTER 11: USING AAA AND RADIUS COMMANDS

Description
Use the stop-accounting-buffer enable command to configure to save the
stopping accounting requests without response in the Switch buffer. Use the undo
stop-accounting-buffer enable command to cancel the function of saving the
stopping accounting requests without response in the Switch buffer.
By default, enable to save the stopping accounting requests in the buffer.
Because the stopping accounting request concerns the account balance and will
affect the amount of charge, which is very important for both the user and ISP,
NAS shall make its best effort to send the message to the RADIUS accounting
server. Accordingly, if the message from the Switch to the RADIUS accounting
server has not been responded to, the Switch shall save it in the local buffer and
retransmit it until the server responds or discard the messages after transmitting
for a specified number of times.
Related commands: reset stop-accounting-buffer, radius scheme, display
stop-accounting-buffer.
Example
To indicate that, for the server “3Com” in the RADIUS scheme, the Switch will
save the stopping accounting request packets in the buffer, enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]radius scheme 3Com
[4500-radius-3Com]stop-accounting-buffer enable

timer

Syntax
timer seconds
undo timer

View
RADIUS Scheme View
Parameter
seconds: RADIUS server response timeout timer, ranging from 1 to 10 and
measured in seconds. By default, the value is 3.

Description
Use the timer command to configure RADIUS server response timer. Use the undo
timer command to restore the default value of the timer.
After a RADIUS (authentication/authorization or accounting) request packet has
been transmitted for a period of time, if NAS has not received the response from
the RADIUS server, it has to retransmit the message to guarantee RADIUS service
for the user. The period taken is called RADIUS server response timeout time,
which is controlled by the RADIUS server response timeout timer in the Switch.
This command is used to set this timer.
Setting a suitable timer according to the network situation will enhance system
performance.

Related commands: radius scheme, retry.
Example
To set the response timeout timer of RADIUS scheme, 3Com, to 5 seconds, enter
the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]radius scheme 3Com
[4500-radius-3Com]timer 5

timer quiet

Syntax
time quiet minutes
undo timer quiet

View
RADIUS Scheme View
Parameter
minutes: Quiet time interval, ranging from 1 to 255 in minutes. The default value

is 5.
Description
Use the timer quiet command to set the quiet time interval after which the
primary and secondary RADIUS scheme servers switch over. Use the undo timer
quiet to set the quiet time interval to its default value.
The functions of the quite time interval are as follows:
1 The Switch sends RADIUS packets to the primary RADIUS server.
2 If the Switch affirms that the primary server does not respond, it then sends
RADIUS packets to the secondary RADIUS server.
3 After each quiet time interval, the Switch sets the status of the primary RADIUS
server to active and sends RADIUS packets to it next time.
Example
To set the quiet time interval of the RADIUS server group ‘3Com’ to 3 minutes,
enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z
[4500]radius scheme 3com
[4500-radius-3com]timer quiet 3

CHAPTER 11: USING AAA AND RADIUS COMMANDS

Parameter
minutes: Real-time accounting interval, ranging from 3 to 60, measured in
minutes in multiples of 3. By default, the value is 12.

Description
Use the timer realtime-accounting command to configure the real-time
accounting interval. Use the undo timer realtime-accounting command to
restore the default interval.
To implement real-time accounting, it is necessary to set a real-time accounting
interval. After the attribute is set, NAS will transmit the accounting information of
online users to the RADIUS server regularly.
The value of minutes is related to the performance of NAS and RADIUS server. The
smaller the value is, the higher the requirement for NAS and RADIUS server is.
When there are a large amount of users (more than 1000, inclusive), we suggest a
larger value. The following table recommends the ratio of minutes value to
number of users.

Parameter
seconds: RADIUS server response timeout timer, ranging from 1 to 10 seconds. By
default, the value is 3.

RADIUS Protocol Configuration Commands

291

Description
Use the timer response-timeout command to configure the RADIUS server
response timer.
Use the undo timer command to restore the default.
If the NAS receives no response from the RADIUS server after sending a RADIUS
request (authentication/authorization or accounting request) for a period of time,
the NAS resends the request, thus ensuring the user can obtain the RADIUS
service. You can specify this period by setting the RADIUS server response timeout
timer, taking into consideration the network condition and the desired system
performance.
Related commands: radius scheme, retry.
Example
To set the response timeout timer in the RADIUS scheme 3Com to 5 seconds,
enter the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]radius scheme 3Com
[4500-radius-3Com]timer response-timeout 5

user-name-format

Syntax
user-name-format { with-domain | without-domain }

View
RADIUS Scheme View
Parameter
with-domain: Specifies to send the username with domain name to RADIUS

server.
without-domain: Specifies to send the username without domain name to

RADIUS server.
Description
Use the user-name-format command to configure the username format sent to
RADIUS server.
By default, the username sent to RADIUS servers includes the ISP domain name.
The supplicants are generally named in userid@isp-name format. The part
following “@” is the ISP domain name. The Switch will put the users into certain
ISP domains according to the domain names. However, some earlier RADIUS
servers reject the username including the ISP domain name. In this case, the
username will be sent to the RADIUS server after its domain name is removed.
Accordingly, the Switch provides this command to decide whether the username
that is to be sent to RADIUS server carries the ISP domain name or not.
If a RADIUS scheme is configured to reject usernames including ISP domain names,
the RADIUS scheme shall not be simultaneously used in more than one ISP

292

CHAPTER 11: USING AAA AND RADIUS COMMANDS

domains. Otherwise, the RADIUS server will regard two users in different ISP
domains as the same user by mistake, if they have the same username (excluding
their respective domain names.)
Related command: radius scheme.
Example
To specify to send the username without domain name to RADIUS server, enter
the following:
<4500>system-view
System View: return to User View with Ctrl+Z.
[4500]radius scheme 3Com
[4500-radius-3Com]user-name-format without-domain

Parameter
count: Enter a value in the range 0 to 32768 to specify how many MAC
addresses a port can learn. 0 means that the port is not allowed to learn MAC
addresses.

Description
Use the mac-address max-mac-count command to configure the maximum
number of MAC addresses that can be learned by a specified Ethernet port. The
port stops learning MAC addresses when the specified limit is reached.
Use the undo mac-address-table max-mac-count command to cancel the
maximum limit on the number of MAC addresses learned by an Ethernet port. This
is the default. If you set no maximum limit, the MAC address table controls the
number of MAC addresses a port can learn.

undo mac-address timer aging

View
System view
Parameter
aging age: Specifies the aging time (measured in seconds) of the Layer-2 dynamic

address table entry, ranging from 10 to 1000000; by default, the aging time is 300
seconds.
no-aging: No aging time.

338

CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS

Description
Use the mac-address timer command to configure the aging time of the Layer-2
dynamic address table entry. Use the undo mac-address timer command to
restore the default value.
Setting the aging time on the switch to be too long or too short will cause the
switch to broadcast data packets without MAC addresses, this will affect the
operational performance of the switch.
If the aging time is set too long, the switch will store out-of-date MAC address
tables. This will consume MAC address table resources and the switch will not be
able to update MAC address table according to the network change.
If aging time is set too short, the switch may delete valid MAC address table
entries.
Example
Configure the entry aging time of Layer-2 dynamic address table to be 500
seconds.

information that can be displayed on your Switch 4500.
Syntax

undo debugging { all | module-name [ debugging-option ] }

View
User view
Parameter
all: Disable all the debugging.
timeout interval: The interval during which the debugging command is valid.
The interval value can range from 1 to 1440 minutes.
module-name: Specify the module name.
debugging-option: Debugging option.

Description
Use the debugging command to enable the system debugging. Use the undo
debugging command to disable the system debugging.
By default, all the debugging processes are disabled.
The Switch provides various kinds of debugging functions for technical support
personnel and experienced maintenance staff to troubleshoot the network.
Enabling the debugging will generate a large amount of debugging information
and decrease the system efficiency. If the debugging all command is used, it will
adversely affect the operational performance of the network. Use the undo
debugging all command to disable all debugging.
By default, if multiple devices form a fabric, the debugging information of the
master is broadcasted within the fabric and the debugging information of the
slave is only displayed on the slave device. You can view the debugging
information including that of the master and the device in which the login port
resides.
You can enable the logging, debugging and trap information switches within the
fabric by executing the info-center switch-on all command. Synchronization
is a process that each switch sends its own information to the other switches in
the fabric, and meantime receives information from others to update local
information, ensuring the consistency of logging, debugging and trap information
in a fabric.
After the synchronization of the whole fabric, a great deal of terminal display is
generated. You are recommended not to enable the information synchronization
switch of the whole fabric. If you enabled the information synchronization switch,

352

CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS

after the synchronization information statistics and detection, you must execute
the undo info-center switch-on command to disable the switch in time.
For the related commands, see display debugging.

By default, when the parameters are not specified:
■

the ECHO-REQUEST message will be sent for 5 times,

■

socket is not in DEBUGGING mode,

■

the TTL value for echo requests is 255,.

■

host will be treated as IP address first. If it is not an IP address, perform domain
name resolution,

■

the default padding operation starts from 0x01 and ends on 0x09
(progressively), then performs again,

■

show all the information including statistics,

■

routes are not recorded,

■

■

default length of ECHO-REQUEST is 56 bytes.,

■

default timeout of ECHO-RESPONSE is 2000ms,

■

do not display other ICMP packets (non ECHO-RESPONSE),

■

the TOS value of echo requests is 0.

The ping command sends ICMP ECHO-REQUEST message to the destination. If
the network to the destination works well, then the destination host will send
ICMP ECHO-REPLY to the source host after receiving ICMP ECHO-REQUEST.
Perform the ping command to troubleshoot the network connection and line
quality. The output information includes:
■

Responses to each of the ECHO-REQUEST messages. If the response message is
not received until timeout, output "Request time out". Or display response
message bytes, packet sequence number, TTL and response time.

Description
Remote-ping is a network diagnostic tool used to test the performance of
protocols (only ICMP by far) operating on network. It is an enhanced alternative to
the ping command.
Remote-ping test group is a set of remote-ping test parameters. A test group
contains several test parameters and is uniquely identified by an administrator
name plus a test tag.
You can perform an remote-ping test after creating a test group and configuring
the test parameters.
Different from the ping command, remote-ping does not display the round trip
time (RTT) and timeout status of each packet on the console terminal in real time.
You need to execute the display remote-ping command to view the statistic results
of your remote-ping test operation. remote-ping allows administrators to set the
parameters of remote-ping test groups and start remote-ping test operations.

string: IP address of the destination host or the hostname of the remote system.

360

CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS

Description
Use the tracert command to check the reachability of network connection and
troubleshoot the network. User can test gateways passed by the packets
transmitted from the host to the destination.
By default, when the parameters are not specified,
first-TTL is 1,
max-TTL is 30,
port is 33434,
nqueries is 3 and
timeout is 5s.

The tracert command sends a packet with TTL 1, and the first hop will send an
ICMP error message back to indicate this packet cannot be transmitted (because
of TTL timeout). Then this packet will be sent again with TTL 2, and the second
hop will indicate a TTL timeout error. Perform this operation repeatedly till
reaching the destination. These processes are operated to record the source
address of each ICMP TTL timeout so as to provide a path to the destination for an
IP packet.
After the ping command finds some error on the network, perform tracert to
locate the error.
The output of the tracert command includes IP address of all the gateways to
the destination. If a certain gateway times out, output "***".
Example
Test the gateways passed by the packets to the destination host at 18.26.0.115.

Description
Use the info-center source command to add/delete a record to the information
channel. Use the undo info-center source command to delete the contents of
the information channel.
For example, for the filter of IP module log output, you can configure to output
the logs at a level higher than warnings to the log host and output those higher
than informational to the log buffer. You can also configure to output the trap
information on the IP module to a specified trap host, etc.
The channels for filtering in all the directions are specified by this configuration
command. All the information will be sent to the corresponding directions
through the specified channels. You can configure the channels in the output
direction, channel filter information, filtering and redirecting of all kinds of
information.
At present, the system distributes an information channel in each output direction
by default, shown as follows:

CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS

After the forming of a Fabric by switches which support the XRN, the log,
debugging and trap information among the switches is synchronous. The
synchronization process is as follows: each switch sends its own information to
other switches in the Fabric and meantime receives the information from others,
and then the switch updates the local information to ensure the information
coincidence within the Fabric.
The switch provides command line to turn on/off the synchronization switch in
every switch. If the synchronization switch of a switch is turned off, it does not
send information to other switches but still receives information from others.
Example
To turn on the trapping information synchronization switch of the unit 2, enter the
following:

3Com recommends that you do not use the notify-view parameter when
configuring an SNMP group, for the following reasons:
■

The snmp-agent target-host command automatically generates a
notify-view for a user, and adds it to the corresponding group.

■

Any change of the SNMP group notify-view will affect all the users related to
this group.

Example
To create an SNMP group named 3Com, enter the following:

NTP Configuration
Commands

To protect unused sockets against attacks by malicious users and improve security,
the Switch 4500 Family provides the following functions:
■

UDP port 123 is opened only when the NTP feature is enabled.

■

UDP port 123 is closed as the NTP feature is disabled.

These functions are implemented as follows:

By default, all protocols are supported.
The configuration takes effect at the next login. After enabling SSH you cannot
login through SSH if the client RSA key is not configured.
If the supported protocol configured in the user interface is SSH, you must ensure
you configure the corresponding authentication mode to authentication-mode
scheme (using AAA authentication mode).
If the authentication mode is configured as authentication-mode password or
authentication-mode none, the configuration of protocol inbound ssh will
fail. However, if a user interface is configured to support the SSH protocol, you will
be unable to configure authentication-mode password and
authentication-mode none.

get a warning asking if you want to replace the existing one. Note that the host
key and the server key must have a difference of 128 bits at least, and that the
minimum and maximum lengths for the host key and the server key are 512 bits
and 2048 bits respectively.
When the client version is SSH 2.0, the RSA key of the SSH server must be no less
than 1024 bits in length, otherwise the authentication will fail
Generating the RSA key pair of the server is the first step to perform after SSH
login. You will not need to generate the RSA key pair after rebooting the Switch.

Parameter
None
Description
Use the ssh client first-time enable command to set the SSH client to
perform the first-time authentication of the SSH server to be accessed.
Use the undo ssh client first-time command to cancel the first-time
authentication.
The first-time authentication means that when the SSH client accesses the server
for the first time in the case that there is no local copy of the server's public key,
the user can proceed to access the server and save a local copy of the server's
public key; when the client accesses the server next time, it uses the saved public
key to authenticate the server.
If the first-time authentication is not supported, when there is no local copy of the
public key of the connected server, the client assumes that the server is illegal and
will refuse to access the server. The user can save a copy of the server's public key
locally by other means beforehand.
By default, the client perform the first-time authentication.
Example
To set the SSH client to perform the first-time authentication of the SSH server to
be accessed, enter the following:

Use the password-control aging enable command to enable password
aging.

■

Use the password-control length enable command to enable the limitation
of the minimum password length.

■

Use the password-control history enable command to enable the history
password recording.
When a password used to log in the switch expires, the switch requires the
user to update the password, and automatically saves the history (old)
password to a file in the flash memory. In this way, the switch can prevent any
user from using one single password for a long time or an old password that
was once used to enhance the security.

■

Use the undo password-control { aging | length | history } enable
command to disable password control.
By default, password aging, limitation of minimum password length, and
history password recording are all enabled.
Related command: password-control.

# Enable password aging.
[4500]password-control aging enable
Password aging enabled for all users. Default: 90 days.

# Enable the limitation of the minimum password length.
[4500]password-control length enable
Password minimum length enabled for all users. Default: 10
characters.

# Disable password aging.
[4500]undo password-control aging
Password aging disabled for all users.

# Enable history password recording.
[4500]password-control history enable
Password history enabled for all users.

# Disable history password recording.
[4500]undo password-control history
