Abstract

Techniques are provided for synchronizing, in a distributed Fiber Channel fabric or a distributed FCoE fabric in which FC frames are encapsulated in Ethernet frames, a controlling FCoE forwarder (cFCF) with the FCoE data-plane forwarder (FDF). The operation includes entering a recovery mode at the FDF. The FDF is modified based on a route distribution message provided by the cFCF which includes fabric-provided MAC addresses (FPMAs). The FDF notifies the cFCF of differences between the FPMAs supplied by the route distribution message with the FPMAs known by the FDF. The FDF leaves the recovery mode and sends an acknowledgement to the cFCF.
