RADIUS Authentication
Click the Configure button, the Security tab, and the Radius Auth sub-tab to set the IP address of the
RADIUS server containing the central list of MAC addresses allowed to access the network.
In large networks with multiple MP.11/a devices, you can maintain a list of MAC addresses on a
centralized location using a RADIUS authentication server that grants or denies access. If you use this
kind of authentication, you must specify at least the primary RADIUS server. The backup RADIUS
server is optional.
Encryption
You can protect the wireless data link by using encryption. Encryption keys can be 5 (64-bit), 13 (WEP
128-bit), or 16 (AES 128-bit) characters in length. Both ends of the wireless data link must use the
same parameter values. Advanced Encryption Standard (AES) encryption is supported on the MP.11a
only.
Click the Configure button, the Security tab, and the Encryption sub-tab to set encryption keys for the
data transmitted and received by the MP.11/a. Note that all devices in one network must use the same
encryption parameters to communicate to each other.

Static MAC Pair Filtering
The Static MAC Address Filter optimizes the performance of a wireless (and wired) network. Click the
Configure button, the Filtering tab, and the Static MAC Pair Filtering sub-tab to access the Static
MAC Address Filter.
The filter is an advanced feature that lets you limit the data traffic between two specific devices (or
between groups of devices based upon MAC addresses) through the wireless interface of the MP.11/a.
For example, if you have a server on your network with which you do not want wireless clients to
communicate, you can set up a Static MAC Filter to block traffic between these devices. However,
note that this is an advanced filter and it may be easier to control wireless traffic through other filter
options, such as Protocol Filtering.
The entry is enabled automatically when saved. To edit an entry, click Edit. To disable or remove an
entry, click Edit and change the Status field from Enable to Disable or Delete.
Wired MAC Address
Enter the MAC address of the device on the Ethernet network that you want to prevent from
communicating with a device on the wireless network.
Wired Mask
Enter the appropriate bit mask to specify the range of MAC addresses to which this filter is to apply.
To specify only the single MAC address you entered in the Wired MAC Address filter, enter
FF:FF:FF:FF:FF:FF (all zeroes).
Wireless MAC Address
Enter the MAC address of the wireless device that you want to prevent from communicating with a
device on the wired network.
Wireless Mask
Enter the appropriate bit mask to specify the range of MAC addresses to which this filter is to apply.
To specify only the single MAC address you entered in the Wireless MAC Address file, enter
FF:FF:FF:FF:FF:FF (all zeroes).

Status
The Status field can show Enable, Disable, or Delete.
Storm Threshold
Click the Configure button, the Filtering tab, and the Storm Threshold sub-tab to prevent
broadcast/multicast overload.
Storm Threshold is an advanced Bridge setup option that you can use to protect the network against
data overload by specifying:
▪ A maximum number of frames per second as received from a single network device (identified by its
MAC address).
▪ An absolute maximum number of messages per port.
The Storm Threshold parameters let you specify a set of thresholds for each port of the MP.11/a,
identifying separate values for the number of broadcast messages per second and multicast messages
per second.
When the number of frames for a port or identified station exceeds the maximum value per second, the
MP.11/a ignores all subsequent messages issued by the particular network device, or ignores all
messages of that type.
Per Address Threshold
Enter the maximum allowed number of packets per second.
Ethernet Threshold
Enter the maximum allowed number of packets per second.
Wireless Threshold
Enter the maximum allowed number of packets per second.

ADDITIONAL INTERFACE INFORMATION
Dynamic Frequency Selection (Tsunami MP.11a only)
With Tsunami MP.11a units, Dynamic Frequency Selection (DFS) is enabled automatically based upon
the country you select. You can tell DFS is in use because the frequency selection drop-down box on
the Interfaces page is grayed out (click the Configure button and the Interfaces tab); it displays only
the DFS-selected frequency. You cannot select a preferred frequency or band in which to operate.
DFS scans all available frequencies in all available bands to select the operating frequency
automatically.
To comply with your country’s regulations, change the DFS selection to specify your country. You can
do this by logging into the unit, clicking the Configure button and selecting the System tab. There is a
drop-down box labeled “Country” with all available countries from which to select. Choose your country,
configure the unit as required, and reboot for the settings to take effect.
Note: Because DFS must scan for radar and interference on multiple channels, you must allow a
sufficient amount of time for the units to start up. This is considerably longer than when the unit
is not using DFS. Startup time is usually within two to three minutes if no radar is detected. If
radar is detected, the unit may reboot multiple times before it becomes fully operational and can
take much longer to start. This is expected behavior.
DFS Requirement
Dynamic Frequency Selection (DFS) is required in ETSI countries and is enabled automatically when
you select a country with a regulatory domain that requires DFS. DFS is required in ETSI countries for
two purposes.
1. Radar avoidance both at startup and while operational. To meet these requirements, the Tsunami
MP.11a BSU scans available frequencies at startup for the presence of a radar signal on all
available frequencies; it does not use any frequency in which radar signals are detected. Once fully
operational on a frequency, the BSU actively monitors the occupied frequency for radar interference.
If radar interference is detected, the BSU logs a message and reboots to find a new frequency free
of interference.
Understand that radar detection is performed only by the BSU and not by the SU. When an SU is
set to a country in which DFS is used, it scans all available channels upon startup looking for a BSU
that best matches its connection criteria (such as Base Station System Name, Network Name,
and Shared Secret). The SU connects to the BSU automatically on whatever frequency the BSU
has selected. Because of this procedure, it is best to set up the BSU and have it fully operational
before installing the SU, although this is not required. If a BSU reboots because of radar
interference, the SU loses its WORP link and reboots to rescan available frequencies for an active
BSU.
Chapter 5. Web Interface 68
CPN 65755 Issue Date: August 2003
Tsunami MP.11and MP.11a Installation and Management
2. Guarantee the efficient use of available frequencies by all devices in a certain area. To meet this
requirement, the BSU scans each available frequency upon startup and selects a frequency based
upon the least amount of noise and interference detected. This lets multiple devices operate in the
same area with limited interference. This procedure is done only at startup; if another non-radar
device comes up on the same frequency, the BSU does not detect this or reboot because of it. It is
expected that other devices using these frequencies also are in compliance with country regulations,
so this should not happen.
Wireless Outdoor Router Protocol
The Wireless Outdoor Router Protocol (WORP) is a polling algorithm designed for wireless outdoor
networks. WORP takes care of the performance degradation incurred by the so-called “hidden-node”
problem, which can occur when standards-based 802.11b wireless LAN technology is used for outdoor
building-to-building connectivity. In this situation, when multiple radios send an RTS, if another radio is
transmitting, it corrupts all data being sent, degrading overall performance. The WORP polling algorithm
ensures that these collisions cannot occur, which increases the performance of the overall network
significantly.
WORP dynamically adapts to the number of satellites that are active on the network and the amount of
data they have queued to send.
Satellite Density
The Satellite Density setting is a valuable feature for achieving maximum bandwidth in a wireless
network. It influences the receive sensitivity of the radio interface. This feature improves operation in
environments with a high noise level. Reducing the sensitivity of the radio enables unwanted “noise” to
be filtered out. (It disappears under the threshold.)
You can configure the Satellite Density to be Large, Medium, Small, Mini, or Micro. The default
value for this setting is Large. The smaller settings are appropriate for high noise environments; a
setting of Large would be for a low noise environment.
A long distance link may have difficulty maintaining a connection with a small density setting because
the wanted signal can disappear under the threshold. Consider both noise level and distance between
the peers in a link when configuring this setting. The threshold should be chosen higher than the noise
level, but sufficiently below the signal level. A safe value is 10 dB below the present signal strength.
If the Signal-to-Noise Ratio (SNR) is not sufficient, a lower data rate selection may be necessary, or use
of antennas with higher gain to increase the margin between wanted and unwanted signals. In a point-
to-multipoint configuration, the Base should have a density setting suitable for all of its registered
Satellites, especially the ones with the lowest signal levels (longest links).
Take care when configuring a remote interface; check the available signal level first, using Remote Link
Test.

Warning!
When the remote interface accidentally is set at too small a value and communication is lost, it
cannot be reconfigured remotely and a local action is required to bring the communication back.
Therefore, the best place to experiment with the level is at the unit that can be managed without
going through the link; if the link is lost, the setting can be adjusted to the correct level to bring
the link back.
To set the Satellite Density, click the Configure button, then the Interfaces tab and the Wireless sub-
tab. Make your density selection from the drop-down menu. This setting requires a reboot of the unit.
Sensitivity threshold settings related to the density settings are:
Satellite Density Large Medium Small Mini Micro
Receive Sensitivity Threshold -99 dBm -90 dBm -85 dBm -72 dBm -66 dBm
Defer Threshold -95 dBm -85 dBm -75 dBm -62 dBm -56 dBm

Chapter 6. Command Line Interface
The Command Line Interface (CLI) provides a text-based interface with which you can configure and
manage the MP.11/a using commands. You can enter these commands or submit them in the form of a
script to allow batch processing. Accessing the CLI is discussed in “Command Line Interface Overview”
in the Tsunami MP.11/a Installation and Management Guide..
Administrators use the CLI to control MP.11/a operation and monitor network statistics. The MP.11/a
supports two types of CLI—the Boot Loader CLI and the normal CLI. The Boot Loader CLI provides a
limited command set and is used when the current Image is bad or missing.
BOOT LOADER COMMAND LINE INTERFACE
The Boot Loader is started when the MP.11/a is switched on or reset, and is responsible for starting the
embedded software. The Boot Loader CLI is available when the MP.11/a embedded software is not
running.
The Boot Loader CLI is a minimal subset of the normal CLI used to perform initial configuration of the
MP.11/a. This interface is accessible only through the serial interface if the MP.11/a does not contain a
software image or a download image command over TFTP has failed.
The Boot Loader CLI lets you configure the initial setup parameters as well as download a software
image to the device.
The following commands are supported by the Boot Loader CLI:
▪ Set for configuration of initial device parameters
▪ Show to view the device’s configuration parameters
▪ Help to provide additional information about all commands supported by the Boot Loader CLI
▪ Reboot to reboot the device
The parameters supported by the Boot Loader CLI (for viewing and modifying) are:
▪ System name
▪ IP address assignment type
▪ IP address
▪ IP mask
▪ Gateway IP address
▪ TFTP Server IP address
▪ Image Filename (including the file extension)

set ipaddr 1 ipaddress 10.0.0.12
Some parameter values change only when the MP.11 is rebooted. In these cases, the CLI warns you
that a reboot is required for the change to take effect.
See “Show and Set Parameters” on page 89 for a list of parameters that can be used with the set
command.

Show Command
The show command lets you view parameter and statistical values. You can view a single parameter, a
group of parameters, or a table with parameters. (A table consists of rows with similar parameters.)
To see a definition and syntax example, enter only show. To see a list of available parameters, enter a
question mark after show (example show ?).
To view the current values of all system parameters: show system
See “Show and Set Parameters” on page 89 for a list of parameters that can be used with the show
command.
Upload Command
The upload command is used to transfer files from the MP.11/a to the TFTP server.
To upload a file from the MP.11/a to the TFTP server:
upload <tftpserveraddress> <path and filename> <filetype>
where <filetype> can be one of these four values:
config - Configuration file, the current settings of the MP.11/a
image - Image file, embedded software for the MP.11/a
bootloader - Boot software
license - License file
To issue repeated operations, use the asterisk (*) character in place of the options:
upload *
Previously used optional values for the upload command is stored in TFTP parameters that you can
view and change. See the TFTP parameter table for details.
CLI BASIC MANAGEMENT COMMANDS
There are a few basic configuration parameters that you may want to set up immediately when you
receive the MP.11/a. For example:
▪ Set System Name, Location, and Contact information
▪ Set IP address for the MP.11/a
▪ Configure interfaces
▪ Set WEP Encryption and passwords
▪ Download an MP.11/a configuration file from your TFTP server
▪ Backup your MP.11/a configuration file
▪ Reboot
▪ Reset to factory defaults

To enter a string with spaces, use single or double quotes. For example, there is no need for quotes in
the following command because the string contains no spaces:
set sysname Lobby
The following string, however, requires quotes because of the space between the words Front and
Lobby.
set sysname “Front Lobby”

Viewing Table Contents
You can view the contents of a table as follows:
show <table name>
Example: This command displays all parameter values of the SNMP IP access table
(snmpipaccesstbl).
show snmpipaccesstbl
Creating a Table Row
You can create a table row as follows:
set <table name> 0 <parameter 1 name> <value 1> … <parameter n name> <value n>
When you create a table row, you must use 0 as row index. Only the mandatory parameters are
required. Optional parameters automatically receive the default value unless a value is given.
Example:
set snmpipaccesstbl 0 ipaddr 10.0.0.10 submask 255.255.0.0
This command adds a row to the SNMP IP access table (snmpipaccesstbl) with the IP address
(ipaddr) and subnet mask (submask) parameters, which are respectively assigned 10.0.0.10 and
255.255.0.0.
Modifying a Table Entry
If you want to change a table entry, you must indicate the index of the table row and the parameter that
must be modified.
Example:
set snmpipaccesstbl 1 ipaddr 10.0.0.11
This command changes the IP address (ipaddr) at row index 1 of the SNMP IP access table
(snmpipaccesstbl) into 10.0.0.11.
Modifying Several Table Entries
You can also modify several table entries at once by indicating the index of the table row and the
parameters that must be modified. With the search command, you can see which parameters are in
the table.
Example:
set snmpipaccesstbl 1 ipaddr 10.0.0.12 submask 255.255.255.248 cmt “First Row”

Enabling, Disabling, or Deleting a Table Row
You can also enable, disable, or delete a row in a table. The syntax of this command is:
<table name> <row> <enable/disable/delete>, or
<table name> <row> status <1/2/3>
Example 1: The following command enables the row at index 2 of the SNMP IP access table
(snmpipaccesstbl).
set snmpipaccesstbl 2 enable
Example 2: The following command disables the row at index 2 of the SNMP IP access table
(snmpipaccesstbl). The status codes have the following meaning: 1 is enable, 2 is disable, 3 is
delete.
set snmpipaccesstbl 2 status 2

Chapter 7. Procedures
This chapter contains a set of procedures, as described in the following table:
Procedure Description
TFTP Server Setup Prepares the TFTP server for transferring files to and from the MP.11/a.
This procedure is used by the other procedures that transfer files.
Image File Download Upgrades the embedded software.
Configuration Backup Saves the configuration of the MP.11.
Configuration Restore Restores a previous configuration through configuration file download.
Soft Reset to Factory
Default
Resets the MP.11/a to the factory default settings through the Web or
Command Line Interface.
Hard Reset to Factory
Default
In some cases, it may be necessary to revert to the factory default
settings (for example, if you cannot access the MP.11/a or you lost the
password for the Web Interface.
Force Reload Completely resets the MP.11 and erases the embedded software. Use
this procedure only as a last resort if the MP.11 does not boot and the
“Hard Reset to Factory Default” procedure did not help. If you perform
a “Forced Reload,” you must download a new image file as described
in “Image File Download with the Boot Loader.”
Image File Download
with the Boot Loader
If the MP.11/a does not contain embedded software, or the embedded
software is corrupt, you can use this procedure to download a new
image file.
TFTP SERVER SETUP
To download or upload a file, you must connect to the computer with the TFTP server through the
MP.11/a’s Ethernet port. This can be any computer in the network or a computer connected to the
MP.11/a with a cross-over Ethernet cable. For information about installing the TFTP server, see
“Installing Documentation and Software” on page 15.
Ensure that the upload or download directory is correctly set, the required file is present in the directory,
and the TFTP server is running. The TFTP server must be running only during file upload and
download. You can check the connectivity between the MP.11/a and the TFTP server by pinging the
MP.11/a from the computer that hosts the TFTP server. The ping program should show replies from the
MP.11/a.

CPN 65755 Issue Date: August 2003
Tsunami MP.11and MP.11a Installation and Management
IMAGE FILE DOWNLOAD WITH THE BOOTLOADER
The following procedures download an image file to the MP.11/a after the embedded software has been
erased with Forced Reload or when the embedded software cannot be started by the Boot Loader.
A new image file can be downloaded to the MP.11/a with ScanTool or the Command Line Interface
through the MP.11/a serial port. In both cases, the file is transferred through Ethernet with TFTP.
Because the CLI serial port option requires a serial RS-232C cable, Proxim recommends the ScanTool
option.
Download with ScanTool
To download an image file with the ScanTool:
1. Set up the TFTP server as described in “TFTP Server Setup” on page 104.
2. Run ScanTool on a computer that is connected to the same LAN subnet as the MP.11/a. ScanTool
scans the subnet for MP.11/a units and displays the found units in the main window. If in Forced
Reload state (Power and Ethernet LEDs are amber), ScanTool will not find the device until the
MP.11/a bootloader times out, and the Power LED turns RED and the Ethernet LED goes OFF.
Click Rescan to re-scan the subnet and update the display.
3. Select the MP.11/a to which you want to download an image file and click Change.
4. Ensure that IP Address Type Static is selected and fill in the following details:
º IP Address and Subnet Mask of the MP.11/a.
º TFTP Server IP Address and, if necessary, the Gateway IP Address of the TFTP server.
º Image File Name of the file with the new image.
5. Click OK to start the file transfer.
The MP.11/a downloads the image file. The TFTP server program should show download activity
after a few seconds. When the download is complete, the LED pattern should return to Forced
Reload state (Power and Ethernet LEDs are amber). the MP.11/a is ready to start the embedded
software.
6. Press and release the Reset button. It may take several seconds to cycle through the Forced
Reload LED pattern and through the initialization LED sequence.
After a Forced Reload procedure, the MP.11/a returns to factory default settings and must be
reconfigured. ScanTool can be used to set the system name and IP address.
To access the MP.11/a see “Chapter 3. Management Overview” on page 19.
Download with CLI
To use the CLI through the serial port of the MP.11/a you need the following items:
▪ A serial RS-232C cable with a male and a female DB-9 connector.
▪ An ASCII terminal program such as HyperTerminal.

Tsunami MP.11and MP.11a Installation and Management
The MP.11/a Responds Slowly
If the MP.11/a takes a long time to become available, it could mean that:
▪ No DHCP server is available.
▪ The IP address of the MP.11/a is already in use.
Verify that the IP address is assigned only to the MP.11/a. Do this by switching off the MP.11/a and
then pinging the IP address. If there is a response to the ping, another device in the network is
using the same IP address. If the MP.11/a uses a static IP address, switching to DHCP mode could
remedy this problem. Also see “Dynamic IP Address with DHCP” on page 21.
▪ There is too much network traffic.
Web Interface Does Not Work
If you cannot connect to the MP.11/a Web server through the network:
1. Connect a computer to the serial port of the MP.11/a and check the HTTP status. The HTTP status
can restrict HTTP access at different interfaces. For more information, see “Serial Port” on page
25.
2. Open a command prompt window and enter:
ping <ip address MP.11> (for example ping 10.0.0.1)
If the MP.11/a does not respond, ensure that you have the correct IP address. If the MP.11/a
responds, the Ethernet connection is working properly, continue with this procedure.
3. Ensure that you are using one of the following Web browsers:
º Microsoft Internet Explorer version 5.0 or later (Version 6.0 or later recommended)
º Netscape version 6.0 or later
4. Ensure that you are not using a proxy server for the connection with your Web browser (with the CLI
command show pelsessions).
5. Ensure that
you have not exceeded the maximum number of Web Interface sessions.

Glossary
ARP DHCP Relay Agent
The Address Resolution Protocol (ARP) is intended
to find the MAC address belonging to an IP address. A feature of the MP.11/a that intercepts DHCP
requests from clients and forwards them to a DHCP
server. For the client, the DHCP Relay Agent of the
MP.11/a functions like a DHCP server. This enables
DHCP requests to pass router boundaries; for
example, it is not required to have a DHCP server on
every IP subnet.
Authentication method
The process the MP.11/a uses to decide whether a
station that wants to register is allowed or not.
IEEE 802.11 specifies two forms of authentication:
open system and shared key; WORP only supports
shared key because of security constraints. Domain Name Server (DNS)
A domain name server is an Internet service that
translates domain names into IP addresses. For
example, www.ietf.org will be translated in
4.17.168.6.
Authentication server “Shared Secret”
This is a kind of password shared between the
MP.11/a and the RADIUS authentication server. This
password is used to encrypt important data
exchanged between the MP.11/a and the RADIUS
server Download
Downloading a file means copying a file from a
remote server to a device or host. In case of the
MP.11/a downloading means transferring a file from
a TFTP server to the MP.11/a.
Authentication server authentication port
This is a UDP port number (default is 1812), which is
used to connect to the authentication server for
obtaining authentication information. Downstream
Downstream means a data stream from the central
part of the network to the end user. See also
upstream.
Backbone
The central part of a network; the backbone network
connects all remote and sub networks to each other
and to the central infrastructure (such as the mail
server, Internet gateway, and so on). Dynamic Host Configuration Protocol
Dynamic Host Configuration Protocol (DHCP) is a
method to dynamically assign IP addresses. If DHCP
is enabled, the device or computer will broadcast a
request that will be answered by a DHCP Server.
Base
If an interface is running in Outdoor mode (WORP), it
is either a base or a satellite interface. A base
interface controls the communication on the channel
and is located in the central part of the network cell.
Multiple satellites can connect to one base; two
bases cannot communicate with each other.
Encryption
Encryption is a means of coding data with a key
before sending it across a network. The same key
must be used to decode the information at the
receiver. This way prevents unauthorized access to
the data that is send across the network.
Broadcast Storm
A broadcast storm is a large series of broadcast
packets (most often caused by wrong network
configuration) that severely impact the network
performance.
Ethernet
Ethernet is the most widely installed Local Area
Network (LAN) technology. The MP.11/a supports
both 10 and 100 Mbps and half and full duplex.
Client IP Address Pool
This a pool of IP addresses from which the MP.11/a
can assign IP addresses to clients, which perform a
DHCP Request.
Gateway
A gateway is network device that connects multiple
(IP) networks to each other. A gateway can perform
protocol conversion.
Configuration Files
A configuration file contains the MP.11/a
configuration details. Configuration items include
among others the IP address and other network-
specific values. Configuration files may be uploaded
to a TFTP server for backup and downloaded into the
MP.11/a for restoring the configuration.
Group
A group is logical collection of network parameters.
For example, the System Group is composed of
several parameters and tables giving system
information of the MP.11/a. All items for a group are
grouped under one tab of the Web Interface and start
with the same prefix for the command line interface.

HTTP Parameter
Hypertext Transfer Protocol (HTTP) is the protocol to
transport Web pages. When you access the Internet
with your browser, the HTTP protocol is used for data
transport (http://www.Tsunamiwireless.com). When
you access the MP.11/a using the Web Interface,
HTTP is used to transport the information.
A parameter is fundamental value that can be
displayed and changed. For example, the MP.11/a
must have a unique IP address and the PC Cards
must know which channels to use. You can view and
change parameters with the Web Interface,
command line interface and SNMP.
ICMP Password
Internet Control Message Protocol (ICMP) is used by
computers and devices to report errors encountered
during processing packets, and to perform other IP-
layer functions, such as diagnostics (‘ping’).
The MP.11/a is password protected. To access the
MP.11/a you need to enter a password before you
can view or change its settings. The default
password is ‘public’.
Image Ping
The image is the binary executable of the embedded
MP.11/a software. To update the MP.11/a you must
download a new image file.
Ping is a basic Internet program that lets you verify if
a particular computer or device with a certain IP
address is reachable. If the computer or device
receives the ping packet, it responds which gives the
ping program the opportunity to display the round-trip
time.
IP Address
A unique numerical address of a computer attached
to the Internet or Intranet. An IP (Internet Protocol)
address consists of a network part and part for a host
(computer) number. An IP address is represented by
four numbers in the range 0 - 255 separated by dots:
for example 10.0.10.1 and 172.21.43.214. See also
subnet mask.
Remote
A remote is a base or a satellite interface. For a base
interface, the number of remotes is the number of
satellites registered; for a satellite interface, there will
be only one remote, which is the base.
LAN RIP
A Local Area Network (LAN) is a network of limited
size to which computers and devices can connect so
that they can communicate with each other.
Routing Information Protocol (RIP) is used between
routers to update routing information so that a router
automatically ‘knows’ which port to use for a certain
destination IP address.
License file
Router
A license file is used to enable certain features of the
MP.11/a. The MP.11/a already has a license file
when it is shipped. When more features become
available, you can purchase a license file and
download it to the MP.11/a to enable these additional
features.
Routers forward packets from one network to another
based on routing information. A router uses a
dynamic routing protocol like RIP or static routes to
base its forwarding decision on.
Satellite
MAC Address If an interface is running in outdoor mode (WORP), it
is either a base or a satellite interface. Satellite
interface behavior is controlled by the base to which
it is registered. Satellites are located in the remote
locations of a network cell. Multiple satellites can
connect to one base; two satellites cannot
communicate with each other. See also WORP and
base.
A MAC (Media Access Control) address is a globally
unique network device address, which is hardware
bound. It used to identify a network device in a LAN.
A MAC address is represented by six two-digit
hexadecimal numbers (0 - 9 and A - F) separated by
colons: for example 00:02:2D:47:1F:71 and
00:D0:AB:00:01:AC.
ScanTool
Management Information Block (MIB)
A computer program that can be used to retrieve or
set the IP address of a locally connected MP.11/a.
A Management Information Block (MIB) is a formal
description of a set of network objects that can be
managed with the Simple Network Management
Protocol (SNMP). A MIB can be loaded by a
management application so that it knows the
MP.11/a specific objects. .
Network Mask
See subnet mask.

Simple Network Management Protocol (SNMP)
A protocol used for the communication between a
network management application and the devices it
is managing. The network management application is
called the SNMP manager; the devices it manages
have implemented SNMP agents. Not only the
MP.11/a but also almost every network device
contains a SNMP agent. The manageable objects of
a device are arranged in a Management Information
Base, also called MIB. The Simple Network
Management Protocol (SNMP) allows managers and
agents to communicate for accessing these objects.
Spanning Tree Protocol (STP)
The Spanning Tree Protocol (STP) can be used to
create redundant networks (“hot standby”) and to
prevent loops. If enabled, spanning tree prevents
loops by disabling redundant links; if a link fails, it
can automatically enable a backup link.
Subnet Mask
A subnet mask is a bit mask that defines which part
of an IP address is used for the network part and
which part for a host (computer) number. A subnet
mask is like an IP address represented by four
numbers in the range 0 - 255 separated by dots.
When the IP address 172.17.23.14 has a subnet
mask of 255.255.255.0, the network part is 172.17.23
of the host number is 14. See also IP address.
Table
Tables hold parameters for several related items. For
example, you can add several potential managers to
the SNMP IP access table. Tables can be displayed
using with the Web Interface, command line interface
and SNMP.
Topology
Topology is the physical layout of network
components (cable, stations, gateways, hubs, and so
on).
Trap
A trap is used within SNMP to report an unexpected
or unallowable condition.
Trivial File Transfer Protocol (TFTP)
Trivial File Transfer Protocol (TFTP) is a lightweight
protocol for transferring files that is like a simple form
of File Transfer Protocol (FTP). A TFTP client is
implemented on the MP.11/a; using the upload and
download commands, the MP.11/a can respectively
copy a file to or from a TFTP server. TFTP server
software is provided on the MP.11/a CD-ROM.
Upload
Uploading a file means copying a file from a network
device to a remote server. In case of the MP.11/a
uploading means transferring a file from the MP.11/a
to a TFTP server. See also download.
Upstream
Upstream means a data stream from the end users
to the central part of the network. See also
downstream.
WEP
The Wired Equivalent Privacy (WEP) algorithm is the
standard encryption method used to protect wireless
communication from eavesdropping.
WORP
The Wireless Outdoor Router Protocol (WORP) was
designed to optimize long distance links and
multipoint networks with Hidden Node effect to
eliminate collisions and loss of bandwidth.
