Abstract
A network switch includes network switch ports, and switching logic for determining the output port for each received layer 2 type data packet. The switching logic includes an address table configured for storing address-based switching decisions, a trunk table configured for assigning each network switch port to a corresponding identified trunk, and a trunk distribution table identifying the network switch ports assigned to each identified trunk. The switching logic determines the output port for each corresponding received layer 2 type data packet based on a corresponding switching decision for the received layer 2 type data packet, and based on selection of an entry in the trunk distribution table based on information within the received layer 2 type data packet. Hence, the network switch is able to perform trunk-based switching with minimal complexity, ensuring switching of data packets at the wire rate.
