After installing the FDDI application, you can configure the FDDI capability for the network you are managing. To configure the FDDI capability to manage your FDDI resources, you use SMIT to define values for:
This chapter describes how to carry out these tasks.
The configuration parameters that you define in SMIT are saved in files with an extension of .conf in the /usr/CML/conf/lnmfddimon directory. These files are read each time LAN Network Manager is started.
In order for SNMP agent programs to forward trap information to LAN Network Manager applications, the agents must be specifically configured. There are two parameters that you might need to configure in the agent programs to communicate with LAN Network Manager and NetView for AIX:
The IP address of the station on which Nways Manager-LAN is installed must be configured in each of the SNMP agent programs. If an agent is not configured with the correct IP address, LAN Network Manager applications cannot correlate traps and provide network topology and status changes.
The steps for configuring an agent program depend on the type of SNMP agent you are configuring. Refer to the documentation for each agent for configuration instructions.
A community name is a password that enables SNMP access to MIB values on an agent. To retrieve and update MIB values, LAN Network Manager applications use the SNMP community names defined in NetView for AIX to build SNMP queries. For these queries to be successful, the community name defined in each SNMP agent program must match the community name defined in NetView for AIX for the agent.
To ensure that the community names match, check the community defined in each agent program, then verify that the names match those defined on the NetView for AIX SNMP Configuration window. To open the SNMP Configuration window, select Options -> SNMP Configuration from the NetView for AIX menu bar.
If the community names do not match, you can change the community name defined either on the NetView for AIX SNMP Configuration window or in the agent program. If the community name defined for an agent in the agent program is public, you do not have to define the community name in NetView for AIX; public is the default community name.
Any change you make to a community name takes effect immediately. It is not necessary to stop and restart Nways Manager-LAN to activate the change. For more information about configuring agent community names, refer to the NetView for AIX User's Guide.
In order for an SNMP bridge or SNMP token-ring to be fully managed by LAN Network Manager, you must configure its time-out parameter with a large enough value so that the resources can be discovered by Nways Manager-LAN. The time-out parameter defines the number of seconds that Nways Manager-LAN waits before updating its LAN submaps.
If you have a large network, be sure to define a longer time-out period so that the agent has enough time to provide all its configuration information before Nways Manager-LAN updates the LAN topology in the LAN submaps.
To change the time-out period defined for an agent program, select Options -> SNMP Configuration from the NetView for AIX menu bar and enter a new time-out value in the SNMP Configuration window.
After you have installed an FDDI SNMP proxy agent on a workstation in each segment that you are managing, configure each agent so that Nways Manager-LAN can communicate with it.
Each FDDI SNMP agent is managed by the LAN Network Manager component and has a configuration file that you can modify using SMIT. With SMIT, you can define the IP address of the agent, the number of the segment on which the agent resides, and the polling interval that the agent uses.
To modify the configuration of an FDDI agent, follow these steps:
