Abstract
A network switch configured for switching data packets across multiple ports uses an address table to generate frame forwarding information. A decision-making engine receives a source address, destination address and receive port number along with a virtual local area network (VLAN) ID, if applicable. The decision-making engine searches the address table twice to generate frame forwarding information. The first search is based on the source address and the receive port number of the frame and the second search is based on the destination address and a VLAN index for the received frame. The network switch uses the information generated from the searches to generate the frame forwarding information.
