19 F_Port masterless trunking TABLE 85 F_Port masterless trunking considerations (Continued) Category Description portCfgTrunkPort port, 0 switchCfgTrunk 0 Port Swap The portCfgTrunkPort port, 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. Trunk Master Fastwrite FICON FC4-48 blade FC4-32 blade Access Gateway mode Trunking PID format Long Distance Port mirroring 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. On the FC4-48 blade, F_Port trunking is supported only on ports 0 - 15. If an FC4-32 blade has the Trunk Area enabled on ports 16 - 31 and the blade is swapped with an FC4-48 or 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. configdownload 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 DCC Policy Note: Configurations that are not compatible with F_Port trunking are long distance, port mirroring, non-CORE_PID, and Fast Write. F_Port trunks are not allowed on Inter-Chassis Link (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. DCC policy enforcement for the F_Port trunk is based on the Trunk Area; the FDISC requests to a trunk port are accepted only if the WWN of the attached device is part of the DCC policy against the TA. The PWWN of the FLOGI sent from the AG will be dynamic for the F_Port trunk master. Because you do not know ahead of time what PWWN AG will use, the PWWN of the FLOGI will not go through DCC policy check on an F_Port trunk master. However, the PWWN of the FDISC will continue to go through DCC policy check. 440 Fabric OS Administrator's Guide 53-1001336-01
