Abstract
A network device includes at least one source physical port configured to be coupled to a network, a plurality of egress ports, and a packet processor. The packet processor includes a processing stage configured to implement a logical port assignment mechanism to assign source logical port information to a data packet received via one of the at least one source physical port, wherein the source logical port information is based on characteristics of the data packet, wherein the source logical port information corresponds to a logical entity that is different from any source physical port, and a forwarding engine to determine one or more egress ports for forwarding the data packet based on at least the assigned source logical port information.
