Description: Type of group address.

Setting this object to the value invalid(2) invalidates the corresponding entry in the ieee8023GroupTable. That is, it effectively disassociates the interface identified with said entry from the group address identified with said entry. Whether the agent removes an invalidated entry from the table is an implementation-specific matter. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such entries requires examination of the relevant ieee8023GroupType object.

A value of flatnet(3) indicates a multicast address for Synoptics autotopology flat net hello messages. A value of segmentnet(4) indicates a multicast address for Synoptics autotopology segment net hello messages.
