Abstract:
1. A method, comprising: receiving a data packet at a network switch, the packet having a destination address that is reached via a Link Aggregation group on a virtual local area network (VLAN); performing a forwarding database lookup to determine a Link Aggregation port reference number for the data packet on the VLAN; searching a Link Aggregation port table to determine a primary Link Aggregation port and a backup Link Aggregation port for forwarding the packet based at least on the Link Aggregation port reference number; searching a port array to determine if the primary Link Aggregation port is valid; forwarding the packet on the primary Link Aggregation port if the primary port is valid; and forwarding the packet on the backup Link Aggregation port if the primary port is not valid.
