RFC 2863: The Interfaces Group MIB
RFC 2863: The Interfaces Group MIB
RFC 2863 is supported only on the Brocade NetIron XMR, Brocade NetIron MLX, Brocade MLXe,
Brocade NetIron CES, and Brocade NetIron CER series devices.
ifIndex
On the Brocade NetIron XMR, Brocade NetIron MLX, and Brocade MLXe devices, there can be 20,
40, 48, or 64 ifIndexes per module. (Refer to the Configuring SNMP ifIndex section of the
Configuring Basic Parameters chapter in the NetIron Configuration Guide for details.) The default
is 20. Issue the snmp-server max-ifindex-per-module 40 CLI command to change the ifIndex to 40
(for example, for backward-compatibility).
On the Brocade NetIron XMR, Brocade NetIron MLX, and Brocade MLXe devices, every trunk group
will appear as a row within the ifTable and ifXTable. The ifIndex range involves all the physical ports,
virtual ports, loopback ports, multicast tunnels, GRE tunnels, MPLS tunnels, and Trunks in that
order.
Use the Get operations on snInterfaceLookupIfIndex (indexed by ifIndex) to get InterfaceId (in a
simple OID form).
Table 2 details the XMR or MLX index ranges and they are subject to change from one release to
the next.
