The Interfaces Table
The Interfaces table contains information on the entity's interfaces. Each interface
is thought of as being attached to a `subnetwork'. This term should not be
confused with `subnet' which refers to an addressing partitioning scheme used in
the Internet suite of protocols.
ifIndex (1.3.6.1.2.1.2.2.1.1)
A unique value for each interface. Its value ranges between 1 and the value of
ifNumber. The value for each interface must remain constant at least from one
re-initialization of the entity's network management system to the next
re-initialization. The range will be non-contiguous.
