Table 82 F_Port masterless trunking considerations Category Description portCfgTrunkPort , 0 switchCfgTrunk 0 Port Swap Trunk Master Fastwrite FICON FC8-48 and FC4-48C blades FC4-32 blade Access Gateway mode Trunking PID format Long Distance Port mirroring configdownload The portCfgTrunkPort , 0 command will fail if a Trunk Area is enabled on a port. The port Trunk Area must be disabled first. The switchCfgTrunk 0 command will fail if a port has TA enabled. All ports on a switch must be TA disabled first. When you assign a Trunk Area to a trunk group, the Trunk Area cannot be port swapped; if a port is swapped, then you cannot assign a Trunk Area to that port. No more than one trunk master in a trunk group. The second trunk master will be persistently disabled with reason "Area has been acquired". When you assign a Trunk Area to a trunk group, the trunk group cannot have fastwrite enabled on those ports; if a port is fastwrite enabled, the port cannot be assigned a Trunk Area. FICON is not supported on F_Port trunk ports. However, FICON can still run on ports that are not F_Port trunked within the same switch. F_Port masterless trunking is supported on ports 16-43 on the FC8-48 blade. On the FC8-48 and FC4-48C blades F_Port trunking supported only on ports 0 - 15. If an FC4-32 (Electron) blade has the Trunk Area enabled on ports 16 - 31 and the blade is swapped with an FC4-48C and FC8-48 blade, the Trunk Area ports will be persistently disabled. You can run the portTrunkArea command to assign a Trunk Area on those ports. Does not support F_Port trunking. It only supports N_Port trunking in AG mode. You must first enable Trunking on the port before the port can have a Trunk Area assigned to it. F_Port masterless trunking is only supported in the CORE PID format. Long distance is not allowed on F_Port trunks, which means a Trunk Area is not allowed on long-distance ports; you cannot enable long distance on ports that have a Trunk Area assigned to them. Port mirroring is not supported on Trunk Area ports or on the PID of an F_Port trunk port. 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. ICL Port AD Note: Configurations that are not compatible with F_Port trunking are long distance, port mirroring, non-CORE_PID, and fastwrite. F_Port trunks are not allowed on ICL Ports. The portTrunkArea command does not allow it. You cannot create a Trunk Area on ports with different Admin Domains. You cannot create a Trunk Area in AD255. 368 Administering ISL Trunking
