Interfaces Group (RFC 1573)

The evolution of the Interfaces Group of MIB II (RFC 1573 converted to

SNMP v1) consists of an object indicating the number of interfaces supported by the DSL router and an interface table containing an entry for each interface. Refer to Table C-3 for the objects supported for the DSL and Ethernet interfaces.

The Interface Stack Group table does not apply, but is required for MIB compliance. One row will be displayed with ifStackHigherLayer=0 and ifStackLowerLayer=0. The ifStackStatus=2 (enumerated value for notInService) and is read-only. The Interface Test Table and the Generic Receive Address Table are not supported.
