ifNumber 1.3.6.1.2.1.2.1
ifNumber 1.3.6.1.2.1.2.1
The number of network interfaces and existing FC ports present on this system, regardless of their
current state. This number will vary across platforms (switches).
The return value is dynamic for all Brocade switches and depends on the number of GbE ports, FC
ports and transport interfaces.
ifTable 1.3.6.1.2.1.2.2
A list of interface entries. The number of entries is given by the value of ifNumber.
The Interfaces table contains information on the entity's interfaces. Each interface is thought of as
being attached to a subnetwork. Note that this term should not be confused with subnet, which
refers to an addressing partitioning scheme used in the Internet suite of protocols.
ifEntry 1.3.6.1.2.1.2.2.1
An interface entry containing objects at the subnetwork layer and below, for a particular interface.
Index ifIndex
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.
For Network Interface, the number starts from 805306369 and increments with the interface
count. For FC ports, the number starts from 1073741824 and increments with the existing FC
ports. Similarly the index value range for the interfaces are as follows:

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.
