Abstract
Apparatuses and methods to manage a global forwarding table in a distributed switch are provided. A particular method may include managing a global forwarding table in a distributed switch. The distributed switch may include a plurality of switch forwarding units. The method may start a timer for an entry in the global forwarding table, and the entry may include a multicast destination address and corresponding multicast membership information. The method may also, in response to expiration of the timer of the entry, check at least one hit status to determine whether at least one switch forwarding unit of the plurality of switch forwarding units has forwarded multicast data to the corresponding multicast membership information of the multicast destination address of the entry. The method may further determine whether the entry is a cast-out candidate based on the hit status.
