1. A fibre channel switch element used for routing fibre channel frames, comprising:

  • a port having a receive segment for receiving fibre channel frames;

    a transmit segment for transmitting fibre channel frames virtual storage area network cache for generating a zone mask of a matching entry; and

    a common segment for storing a look up table that is indexed by port values of a frame'"'"'s destination identifier (D_ID) and a bit map to compare with the zone mask of the matching entry cache generated by the virtual storage area network (“

    VSAN”

    ) cache;

    wherein if the VSAN cache entry is to select a column from the look up table, a logical comparison is performed between the zone map and look up table entries; and

    if there is no match after the comparison and an encapsulation mode is enabled, then a tagging header is stripped from a frame before the frame is transmitted by the transmit segment.
