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.
