ifIndex
OID 1.3.6.1.2.1.2.2.1.1
Description A unique value for each interface.
Note 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.
ifDescr
OID 1.3.6.1.2.1.2.2.1.2
Description A textual string containing information about the interface.
Note 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.
ifType
OID 1.3.6.1.2.1.2.2.1.3

ifMtu
OID 1.3.6.1.2.1.2.2.1.4
Description The size of the largest datagram that can be sent/received on the interface, specified in
