F_Port masterless trunking 19 NOTE You do not need to manually map the host to the master port because Access Gateway will perform a cold failover to the master port. To implement F_Port masterless trunking, you must first configure an F_Port trunk group and statically assign an Area_ID within the trunk group. Assigning a Trunk Area (TA) to a port or trunk group enables F_Port masterless trunking on that port or trunk group. F_Port masterless trunking considerations Table 89 describes the F_Port masterless trunking considerations. TABLE 89 Category F_Port masterless trunking considerations Description Access Gateway mode AD Area assignment Does not support F_Port trunking. It only supports N_Port trunking in AG mode. You cannot create a Trunk Area on ports with different Admin Domains. You cannot create a Trunk Area in AD255. You statically assign the area within the trunk group on the edge switch. That group is the F_Port masterless trunk. The static trunk area you assign must fall within the ASIC's trunk group of the switch or blade starting from port 0. The static trunk area you assign must be one of the port's default areas of the trunk group. Authentication 10-bit addressing is the default mode for all dynamically created partitions in the Brocade DCX platform. Authentication occurs only on the F_Port trunk master port and only once per the entire trunk. This behavior is the same as E_Port trunk master authentication. Because only one port in the trunk does FLOGI to the switch, and authentication follows FLOGI on that port, only that port displays the authentication details when you issue the portShow command. configdownload Note: Switches in Access Gateway mode do not perform authentication. If you issue the configDownload command for a port configuration that is not compatible with F_Port trunking, and the port is Trunk Area-enabled, then the port will be persistently disabled. Note: Configurations that are not compatible with F_Port trunking are long distance, port mirroring, non-CORE_PID, and Fast Write. Fabric OS Administrator's Guide 435 53-1001763-01
