Abstract
A method and system for forwarding traffic through a network node involve translating a virtual local area network identifier (VLAN ID) of received VLAN traffic from an input VLAN ID to an output VLAN ID (or VLAN IDs) before the traffic is transmitted from the network node. In an embodiment, the input VLAN ID is different from the output VLAN ID. In an embodiment, VLAN ID translation occurs at port interfaces within the network node that receive incoming VLAN traffic. In an embodiment, each port interface can be configured to independently translate input VLAN IDs to output VLAN IDs and output ports.
