ABSTRACT:
A switch includes a processor, an ingress port having ingress port logic, and an egress port. It may also include a virtual network identifier rewrite component for rewriting a virtual network identifier in a data frame received the ingress port with a new virtual network identifier. Also included is a virtual network identifier rewrite rule set, where a rule may have one or more of the following: a received virtual network identifier, a source Fibre Channel identifier (FCID) address, an ingress port identifier, and a new virtual network identifier. The ingress port logic may insert a received virtual network identifier into the data frame received at the ingress port, where the virtual network identifier may correspond to the ingress port. The virtual network identifier rewrite component may assign the new virtual network identifier to the data frame according to a specific virtual network identifier rewrite rule.
