摘要

An apparatus comprising a Virtual Local Area Network (VLAN) mapper associated with a plurality of interfaces and a plurality of ports corresponding to the interfaces, wherein the VLAN mapper is configured to direct a plurality of packets between the interfaces and the corresponding ports based on a VLAN mapping table. Also included is an apparatus comprising at least one processor configured to implement a method comprising receiving a packet via an interface, determining whether the packet is tagged, mapping the packet to a port corresponding to the interface using a mapping table if the packet is tagged, and mapping the packet to a designated port using a default marking attribute if the packet is untagged.
