Configuring Basic Parameters : Configuring SNMP ifIndex

Configuring SNMP ifIndex
This section explains how ifIndex values are assigned on Brocade devices.
On Brocade NetIron CES and Brocade NetIron CER only
On the Brocade NetIron CES and Brocade NetIron CER, the system automatically assign 64 indexes to each module on the device. This value is not configurable.
On Brocade NetIron XMR and Brocade MLX series only
On Brocade NetIron XMR and Brocade MLX series devices, SNMP Management Information Base (MIB) uses Interface Index (ifIndex) to assign a unique value to each port on a module or slot. The number of indexes that can be assigned per module is 20, 40, or 64, depending on the number of ports on the module.
Enter the following to change the number of indexes per module.
Brocade(config)# snmp-server max-ifindex-per-module 40
 
Syntax:
20 is the default.
You cannot change the maximum ifIndex per module to a number less than the number of ports.
After this command is issued the following are generated:
Configuration notes for the Brocade NetIron XMR and Brocade MLX series
Note the following if you are upgrading the software on the Brocade NetIron XMR and Brocade MLX series:
If you are running an earlier version of the software and you will be installing the NI-MLX-1Gx48-T module on you Brocade MLX series, you must configure the maximum ifIndex per module to 64. You must change the ifIndex allocation before installing the NI-MLX-1Gx48-T module; otherwise, the module status remains in the Offline state.
If you have a new Brocade MLX series (no previous software installed), and you will be installing an NI-MLX-1Gx48-T module, you must configure the maximum ifIndex per module to 64; otherwise, the module remains in the Offline state.
