Abstract
A method and apparatus for packet switching using distributed address tables. A first table of station addresses and their associated switching device ports is maintained on a central node of a switching device. Entries in the first table are based on learning information associated with packets forwarded by the central node. A second table of station addresses and their associated switching device ports is maintained on a local node of the switching device. Entries in the second table are based on learning information associated with packets forwarded by the local node. The packets forwarded by the local node include packets not forwarded by the central node so that the first and second tables of station addresses are different from one another.
