Abstract
A method of packet processing includes receiving a packet at one of a plurality of network ports at a switch device, tagging the packet with a first identification, tagging the packet with a second identification, using a first table to determine a first set of output port identifications based at least in part on the first identification, using a second table to determine a second set of output port identifications based at least in part on the second identification, and performing a logical operation using the first set of output port identifications and the second set of output port identifications to identify one or more of a plurality of output ports at the switch device.
