Abstract:
1. A method comprising: at a first switch in a network, receiving a login request from a first endpoint device that is associated with a first FC identifier (FCID) that was previously assigned to the first endpoint device by a second switch in the network, wherein the second switch is associated with a different domain than the first switch; determining that the first endpoint device has been migrated to the first switch; responding to the login request with the first FCID; assigning the first endpoint device a second FCID associated with a domain of the first switch, wherein the second FCID is used as a proxy FCID between switches in the network for the first endpoint device; receiving a first frame from the first endpoint device with a source FCID comprising the first FCID and a destination FCID comprising an FCID for a second endpoint device; overwriting the source FCID in the first frame with the second FCID such that the first frame is associated with the domain of the first switch domain after transmission from the first switch; and forwarding the first frame to the second endpoint device associated with a third switch.
