Explanation

FC Addressing in Switched Fabric An FC address is dynamically assigned when a node port logs on to the fabric. The FC address has a distinct format, as shown in the slide. The first field of the FC address contains the domain ID of the switch. A Domain ID is a unique number provided to each switch in the fabric. Although this is an 8-bit field, there are only 239 available addresses for domain ID because some addresses are deemed special and reserved for fabric management services. For example, FFFFFC is reserved for the name server, and FFFFFE is reserved for the fabric login service.
