2 Access Gateway mapping • When configuring secondary port mapping for failover and failback situations, make sure that initiator and target F_Ports will not fail over or fail back to the same N_Port. Brocade 8000 mapping differences The Brocade 8000 contains 24 internal FCoE ports and eight external Fibre Channel ports. In Access Gateway mode, the internal FCoE ports are configured logically as F_Ports, while the external Fibre Channel ports are configured as N_Ports. The FCoE ports are divided into six groups or trunks consisting of four ports each. All four ports in a group are mapped to one N_Port. Although you can change the default port mapping for these groups (refer to "Default port mapping" on page 12), consider the following when working with these FCoE ports: • All four FCoE ports in the group are mapped to the same N_Port. • You cannot map individual FCoE ports within the same port group to different N_Ports. • Any Access Gateway operation that involves moving F_Ports will move all FCoE ports in the group. • All four FCoE ports in a group will failover or failback to one N_Port. Default port mapping Table 5 shows the default port mapping. By default, Failover and Failback policies are enabled on all N_Ports. NOTE All POD licenses must be present to use Access Gateway on the Brocade 5100 and 300. .TABLE 5 Brocade Model VA40-FC Access Gateway default port mapping Total Ports F_Ports N_Ports 40 0-31 32-39 300 24 0-15 16 -23 Default Port Mapping 0-3 mapped to 32 4-7 mapped to 33 8-11 mapped to 34 12-15 mapped to 35 16-19 mapped to 36 20-23 mapped to 37 24-27 mapped to 38 28-31 mapped to 39 0, 1 mapped to 16 2, 3 mapped to 17 4, 5 mapped to 18 6, 7 mapped to 19 8, 9 mapped to 20 10, 11 mapped to 21 12, 13 mapped to 22 14, 15mapped to 23 12 Access Gateway Administrator's Guide 53-1001760-01
