Brocade Fabric OS MIB Reference - Supporting Fabric OS 5.3.0 (53-1000439-01, June 2007)

Fabric OS MIB Reference 21

53-1000439-01

ifIndex 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.

The number of entries inside the Brocade 12000, 24000, and 48000 directors is 1 to 3 for FCIP;

otherwise, the value is 1 or 2.

ifDescr 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 Brocade 12000, 24000, and 48000 directors includes:

lo, eth0, fc0, and sit0, as well as fc1, eth0:1, and eth0:2.

ifType 1.3.6.1.2.1.2.2.1.3

The type of interface, designated by the physical/link protocol(s) immediately below the network

layer in the protocol stack.

Values

• eth0 maps to 6 (Ethernet-csmacd)

• lo maps to 24 (softwareLoopback)

• fc0 maps to 56

ifMtu 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.

Values 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 v4.x).

• eth0 returns 1500

• lo returns 16436

• fc0 returns 2024

ifSpeed 1.3.6.1.2.1.2.2.1.5

An estimate (in bits per second) of the interface's current bandwidth.

Values For interfaces that do not vary in bandwidth or interfaces for which no accurate estimation can be

made, this object should contain the nominal bandwidth. For Fabric OS v4.x, 2 Gbit/sec returns.

• eth0 returns 107

• lo returns 0

• fc0 returns 2000000000
