This object is an 'alias' name for the lower-layer interface on top of which this IP interface is defined. The alias is specified by the network manager, and provides a non-volatile 'handle' for the lower-layer interface. The semantics of the object are similar to the semantics of the ifAlias object, defined by the Interfaces MIB. At the time when this Madge MIB object was defined, the latest release of the Interfaces MIB was draft-ietf-ifmib-mib-05.txt. The purpose is to support all methods (static or dynamic) for creation of interfaces and to allow creation of IP table entries without the need of the layer 2 interface to be present on the device at the time of the creation. It is assumed that some implementation dependent mechanisms allow the IP application to be informed about the creation of new lower layer interfaces.
