Abstract

Method to perform an operation comprising, receiving a login request from an endpoint connected to first physical port of a first switch module of a distributed network switch, wherein the distributed network switch comprises a plurality of switch modules, wherein each switch module comprises a plurality of ASICs, responsive to the login request, storing, in a FCDF database, an entry comprising an identifier of the first physical port and a unique identifier of the endpoint, and responsive to receiving, from a cFCF, a zoning update comprising the unique identifier of the endpoint and an FCID for the endpoint, storing the FCID in the FCDF database entry for the endpoint, identifying a first ASIC, of the plurality of ASICs of the first switch module, connected to the first physical port, and updating a zoning table of the first ASIC to include the zoning update.
