摘要：A network switch for network communications is disclosed. The switch includesa first data port interface supporting at least one data port transmitting and receivingdata at a first data rate and a second data port interface supporting at least one dataport transmitting and receiving data at a second data rate. The switch also has a CPUinterface configured to communicate with a CPU and a memory management unit forcommunicating data from at least one of the first and second data port interfaces and amemory. It also includes a communication channel for communicating data andmessaging information between the first and second data port interfaces and thememory management unit and a plurality of lookup tables, including an address

resolution lookup table and a VLAN table. One of the first or second data port interfacesis configured to determine an egress ports or egress ports for an incoming data packetfrom a search of the address resolution lookup table and the VLAN table using a VLANID derived from the incoming data packet. Methods directed to forwarding data packetand learning absent addresses are also disclosed.
