3 Trunking in Access Gateway mode AG trunking considerations for the Edge switch Table 10 describes the Access Gateway trunking considerations for the Edge switch. TABLE 10 Category Access Gateway trunking considerations for the Edge switch Description Area assignment 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 F_Port trunk group starting from port 0 on an Edge switch or blade. Authentication The static trunk area you assign must be one of the port's default areas of the trunk group. 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. Management Server Trunk area PWWN Downgrade Note: Authentication is also supported on switches configured in AG mode. Registered Node ID (RNID), Link Incident Record Registration (LIRR), and Query Security Attributes (QSA) Extended Link Service Requests (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 shares 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 11 on page 65. You can have trunking on, but you must disable the trunk ports before performing a firmware downgrade. Upgrade HA Sync Port Types 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 7.1.0 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. 62 Access Gateway Administrator's Guide 53-1002743-01
