Abstract:
1. A method for routing a frame received at a receive segment of a port of a network device, comprising: (a) determining if support for routing the frame in a virtual storage area network (“VSAN”) is enabled at the port of the network device; (b) when the frame includes a VSAN identifier, comparing the VSAN identifier of the frame with a plurality of entries stored for the port; (c) when there is a match with one of the entries, then setting an indicator indicating that a match was found; (d) using the VSAN identifier for determining a destination port; (e) determining if VSAN encapsulation mode is enabled for adding a tagging header to the frame; wherein the tagging header includes the VSAN identifier value for identifying the VSAN; and (f) when VSAN encapsulation mode is enabled, then adding the tagging header to the frame, before routing the frame to the destination port.
