A network switch includes a plurality of first network ports coupled to a first bus, a plurality of second network ports coupled to a second bus, a bridge interface enabling data transfer between the buses, a switch manager controlling the flow of network data, and a processor for performing supervisory and control functions. The first and second network ports operate according to different network protocols, and the first and second buses operate according to different bus standards. During packet data transfers across the first bus, the bridge interface emulates a first network port. During packet data transfers across the second bus, the bridge interface primarily acts as a slave to the second network ports by storing control lists for execution by the second network ports, thus relieving the processor of performing overhead functions associated with data transfers across the second bus.
