ABSTRACT:
A method and system for logical group endpoint discovery in a data communication network is disclosed. A network endpoint receives from a source a request identifying a logical group and determines whether a port associated with the endpoint is a member of the logical group. If a port associated with the endpoint is a member of the logical group, the endpoint transmits to the source a reply identifying the port and the logical group. The request may be multicast while the reply may be unicast. The logical group may be a VLAN or a multicast group. The source and endpoint are preferably 802.1ag maintenance endpoints. The request may include an IEEE 802.1ag continuity check multicast address as a destination address.
