Usage Guidelines Fibre Channel standards require a unique FCID to be allocated to an N port attached to a Fx port in any switch. To conserve the number of FCIDs used, Cisco Nexus 5000 Series switches use a special allocation scheme. Some HBAs do not discover targets that have FC IDs with the same domain and area. The switch software maintains a list of tested company IDs that do not exhibit this behavior. These HBAs were allocated with single FC IDs, and for others a full area was allocated. To allow further scalability for switches with numerous ports, the switch software maintains a list of HBAs exhibiting this behavior. Each HBA is identified by its company ID (also known as Organizational Unique Identifier, or OUI) used in the pWWN during a fabric log in. A full area is allocated to the N ports with company IDs that are listed and for the others, a single FC ID is allocated. Regardless of the type (whole area or single) of FC ID allocated, the FC ID entries remain persistent. Examples The following example adds a new company ID to the default area company ID list: switch(config)# fcid allocation area company-id 0x003223 8-56 Cisco Nexus 5000 Series Command Reference OL-16599-01
