A L2 sub-interface is a logical bridging endpoint associated with traffic on an interface distinguished by 802.1Q tags, where each <interface, 802.1q tag> tuple is treated as a first class bridging interface. Like other types of interfaces, a L2 sub-interface is a normal bridging endpoint in the bridging domain.
