Abstract
A network switch and a method thereof for network communications include a first data port interface and a second data port interface supporting a data port transmitting and receiving data at a first data rate and a second data rate, respectively. The switch has a CPU interface to communicate with a CPU and a memory management unit to communicate data from at least one of the first and second data port interfaces and a memory. The switch includes a communication channel communicating data and messaging information between the first and second data port interfaces and the memory management unit and lookup tables, including an address resolution lookup table and a VLAN table. The first or second data port interfaces determine an egress port for an incoming data packet from a search of the address resolution lookup table and the VLAN table using a VLAN ID from the incoming data packet.
