3 Trunking in Access Gateway mode TABLE 8 Category Access Gateway trunking considerations for the Edge switch (Continued) Description FC4-32 blade Trunking PID format Long Distance If an FC4-32 blade has the Trunk Area enabled on ports 16 - 31 and the blade is swapped with a 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. 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 CORE PID format. Long distance is not allowed when AG is enabled on a switch. This means you cannot enable long distance on ports that have a Trunk Area assigned to them. Port mirroring Port speed configdownload and configupload Port mirroring is not supported on Trunk Area ports or on the PID of an F_Port trunk port. Ports within a trunk must have the same port speed for a trunk to successfully be created. 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 Fastwrite. ICL port AD DCC Policy If you issue the configupload command, consider the following: • A configuration file uploaded when AG mode is disabled cannot be downloaded when AG mode is enabled. • A configuration file uploaded when AG mode is enabled cannot be downloaded when AG mode is disabled. • A configuration file uploaded when the PG policy is enabled cannot be downloaded when the APC policy is enabled. • A configuration file uploaded when the APC policy is enabled cannot be downloaded when the PG policy is enabled. 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. DCC policy enforcement for the F_Port trunk is based on the Trunk Area; the FDISC requests to a trunk port is 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. 56 Access Gateway Administrator's Guide 53-1001760-01
