FCoE uses a Fabric Provided MAC Address (FPMA) for SAN traffic. The ENode still gets a 24-bit FCID. FPMA is built by concatenating a 24-bit FCoE MAC address prefix (FC-MAP), ranging from 0x0E-FC-00 to 0x0E-FC-FF, to the 24-bit FCID, as shown in Figure 9-13. Being able to build a unique MAC address for the ENode […]
