ABSTRACT:
A bridge and method are described herein that translate at least a portion of a port VID (VLAN identifier) for an incoming tagged frame to form a relay VID for a corresponding relay tagged frame by using a VID mask table, a VID filter table, and a VID rule table. In an additional embodiment, the bridge and method also implement a port VLAN membership technique to ensure that an ingress port associated with the port VID is a member of the current VLAN.
