ABSTRACT:
A Fibre Channel Switch element and method for Inter-Fabric routing is provided. The switch element includes a switch port whose worldwide port number is used in a zone set to enable Inter-Fabric frame routing without using Inter-Fabric frame headers. The method includes querying a Name Server to determine world wide port numbers of devices; storing query results in an Inter-Fabric Name Server module; extracting world wide port numbers for each switch port; registering Proxy Devices with the Name Server, wherein the Proxy Devices interface with the switch ports as if it was they were actual devices to route Inter-Fabric frames; and establishing Fabric Address Translator entries so that source identification values and destination identification values are mapped to route Inter-Fabric frames without using Inter-Fabric frame headers.
