Interfaces Group

The Interfaces Group as defined in RFC 1573 consists of an object indicating the

number of interfaces supported by the unit and an interface table containing an

entry for each interface. Since RFC 1573 is an SNMPv2 MIB, it is converted to

SNMPv1 for support by the unit. The following table provides clarification for

objects contained in the Interfaces group when it is not clear how the object

definition in RFC 1573 is supported by the unit.
