Abstract
Apparatuses and methods to request multicast membership information in a distributed switch are provided. A particular method may include requesting multicast membership information of a group identified by a multicast destination address in a distributed switch. The distributed switch may include a plurality of distributed switch elements with a plurality of switch forwarding units. The method may generate a miss event indicating that the multicast destination address is unregistered in a switch forwarding unit of a distributed switch element and there is a need for the multicast membership information. The method may also request the multicast membership information of the multicast destination address in response to the miss event. The method may further initiate a query for the multicast membership information of the multicast destination address in response to the request.
