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.

Fibre channel over ethernet (FCoE) zoning in a distributed ethernet switch

Techniques are provided for distributing a fabric name to switching elements of a distributed switch configured to forward Fibre Channel over Ethernet (FCoE) frames. A distributed switch membership distributed (DMFD) message is transmitted that includes names of all switching elements in the distributed switch, and further includes a fabric descriptor that contains the fabric name.

Maintaining a fabric name across a distributed switch

Systems, methods, and computer program products 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.

A method implemented as a computer program product for comparing two designs of electronic circuits, wherein the design representations comprise several hierarchically related sheets. The method comprises the steps of (a) identifying corresponding top-sheets of the first hierarchy level in the design versions; (b) generating a list of all sub-sheets for each top-sheet and comparing the lists to identify added, removed and common sheets of the corresponding top-sheets; (c) defining the common sheets as corresponding top-sheets of a next hierarchy level; and (d) repeating steps (a)-(c) until at least one of the top-sheets does not comprise any sub-sheet.
