Abstract

Techniques are provided for two components in a distributed Fiber Channel Forwarder (FCF) to establish a link between them at a level of operation that is mutually compatible with respect to the various capabilities offered by the two components. A controlling switch in the distributed FCF may simultaneously operate at different levels with different Fiber Channel Data-Plane Forwarders (FDFs), on a per-pair basis. The level of operation is established at the granularity of an individual capability offered by a switching element. When switching elements are upgraded, the switching elements can dynamically switch to higher or lower levels of operation for any or all of the capabilities defined per pair of switching element.
