Abstract: A network switch that has a plurality of input ports that receive data packets. An external interface is connected to the plurality of input ports. The external interface externally transmits the data packets for processing, and receives the data packets after processing. A memory management unit is connected to the external interface and a plurality of output ports are connected to the memory management unit.

Abstract: A method of forwarding data in a network switch fabric is disclosed. An incoming data packet is received at a first port of the fabric and a first packet portion, less than a full packet length, is read to determine particular packet information, the particular packet information including a source address and a destination address. An egress port bitmap is determined based on a lookup in a forwarding table and it is determined if the destination address belongs to a trunk group of trunked ports. The incoming data packet is forwarded based on the egress port bitmap, when the destination address does not belong to the trunk group. When the destination address does belong to the trunk group, a particular trunked port of the trunk group is determined and the incoming data packet is forwarded thereto.
