1.3.6.1.2.1.2.2.1.1
A unique value for each interface.
The values range between 1 and the value of ifNumber. The value for each interface must
remain constant, at least from one reinitialization of the entity's network management
system to the next reinitialization.
For example, the number of entries inside the Core Switch 2/64, SAN Director 2/128,
and 4/256 SAN Director is 1, 2, or 3 for FCIP; otherwise, the value is 1 or 2.
1.3.6.1.2.1.2.2.1.2
A textual string containing information about the interface.
The ifDescr for non-bladed switches includes: lo, eth0, and fc0.
The ifDescr for Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director
includes: lo, eth0, and fc0, as well as fc1, eth0:1, and eth0:2.
1.3.6.1.2.1.2.2.1.3
The type of interface, designated by the physical/link protocols immediately below the
network layer in the protocol stack.
eth0 maps to 6 (Ethernet-csmacd).
lo0 maps to 24 (softwareLoopback).
fc0 maps to 56.
1.3.6.1.2.1.2.2.1.4
The size of the largest datagram that can be sent/received on the interface, specified in
octets.
For interfaces that are used to transmit network datagrams, the value is the size of the
largest network datagram that can be sent on the interface (these values are different for
Fabric OS 4.x).
fei0 returns 1500.
lo0 returns 3904.
fc0 returns 2024.
