Configure LNM Software on the Management Stations to Communicate with the Router

Configuring Source-Route Bridging BC-129

When SRB is enabled on the router, configuring the Cisco IOS software to perform the functions of

an IBM Bridge for communication with LNM occurs automatically. Therefore, if SRB has been

enabled, you do not need to perform any tasks to enable LNM support. However, the LNM software

residing on a management station on a Token Ring on the network should be configured to properly

communicate with the router.

There are several options for modifying LNM parameters in the Cisco IOS software, but none are

required for basic functionality. For example, because users can now modify the operation of the

Cisco IOS software through SNMP as well as through LNM, there is an option to exclude a user from

modifying the Cisco IOS software configuration through LNM. You also can specify which of the

three LNM services (CRS, REM, RPS) the source-route bridge will perform.

To configure LNM support, perform the tasks in the following sections:

• Configure LNM Software on the Management Stations to Communicate with the Router

• Disable LNM Functionality

• Disable Automatic Report Path Trace Function

• Prevent LNM Stations from Modifying Cisco IOS Software Parameters

• Enable Other LRMs to Change Router Parameters

• Apply a Password to an LNM Reporting Link

• Enable LNM Servers

• Change Reporting Thresholds

• Change an LNM Reporting Interval

• Enable the RPS Express Buffer Function

• Monitor LNM Operation

Configure LNM Software on the Management Stations to Communicate with the

Router

Because configuring an LNM station is a fairly simple task and is well covered in the LNM

documentation, it is not covered in depth here. However, it is important to mention that you must

enter the MAC addresses of the interfaces comprising the ports of the bridges as adapter addresses.

When you configure the router as a multiport bridge, configuring an LNM station is complicated by

the virtual ring that is involved. The basic problem extends from the fact that LNM is designed to

only understand the concept of a two-port bridge, and the router with a virtual ring is a multiport

bridge. The solution is to configure a virtual ring into the LNM Manager station as a series of

dual-port bridges.

Disable LNM Functionality

Under some circumstances, you can disable all LNM server functions on the router without having

to determine whether to disable a specific server, such as the ring parameter server or the ring error

monitor on a given interface.

To disable LNM functionality, use the following command in global configuration mode:

Command Purpose

lnm disabled Disable LNM functionality.
