TRUNKING SUPPORT IN A HIGH PERFORMANCE NETWORK DEVICE

摘要

A method and apparatus for providing trunking support in a network device (201) is provided. The network device includes at least one port that is configured to be included in a trunk and a memory for storing a forwarding database (240). The forwarding database includes entries containing therein forwarding information for a subset of network addresses. The network device further includes a learning circuit (260) coupled to the trunked port and the memory. The learning circuit is configured to modify the forwarding database to reflect an association between the trunked port and a first address contained within a packet received by the trunked port. If the trunk is of a first type, the learning circuit updates the forwarding database based upon a trunk designator corresponding to the trunk, otherwise the learning circuit updates the forwarding data base based upon a port designator corresponding to the trunked port.
