Trunking in Access Gateway mode 3 TABLE 8 Category Access Gateway trunking considerations for the Edge switch Description Authentication Authentication occurs only on the F_Port trunk master port and only once per the entire trunk. This behavior is 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. Management Server Trunk area PWWN Downgrade Note: Switches in Access Gateway mode do not perform authentication. Registered Node ID (RNID), Link Incident Record Registration (LIRR), and (QSA) Query Security Attributes ELSs are not supported on F_Port trunks. The port must be disabled before assigning a Trunk Area on the Edge switch to the port or removing a Trunk Area from a trunk group. You cannot assign a Trunk Area to ports if the standby CP is running a firmware version earlier than Fabric OS V6.2.0. The entire Trunk Area trunk group share the same Port WWN within the trunk group. The PWWN is the same across the F_Port trunk that will have 0x2f or 0x25 as the first byte of the PWWN. The TA is part of the PWWN in the format listed in Table 9 on page 45. You can have trunking on, but you must disable the trunk ports before performing a firmware downgrade. Upgrade HA Sync Port Types Default Area portCfgTrunkPort port, 0 switchCfgTrunk 0 Port Swap Trunk Master Note: Removing a Trunk Area on ports running traffic is disruptive. Use caution before assigning a Trunk Area if you need to downgrade to a firmware earlier than Fabric OS v6.1.0. No limitations on upgrade to Fabric OS v6.3.0 if the F_Port is present on the switch. Upgrading is not disruptive. If you plug in a standby-CP with a firmware version earlier than Fabric OS v6.1.0 and a Trunk Area is present on the switch, the CP blades will become out of sync. Only F_Port trunk ports are allowed on a Trunk Area port. All other port types that include F/FL/E/EX are persistently disabled. Port X is a port that has its Default Area the same as its Trunk Area. The only time you can remove port X from the trunk group is if the entire trunk group has the Trunk Area disabled. portCfgTrunkPort port, 0 will fail if a Trunk Area is enabled on a port. The port must be Trunk Area-disabled first. switchCfgTrunk 0 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". Access Gateway Administrator's Guide 43 53-1001345-01
