Assigning a Trunk Area

Ports from different ADs are not allowed to join the same Trunk Area group. The portTrunkArea
command prevents the different ADs from joining the TA group.
When you assign a TA, the ports within the TA group have the same Index. The Index that was
assigned to the ports is no longer part of the switch. Any Domain,Index (D,I) AD that was assumed
to be part of the domain may no longer exist for that domain because it was removed from the
switch.

F_Port masterless trunking considerations (Continued)
Description
Registered Node ID (RNID), Link Incident Record Registration (LIRR), and Query
Security Attribute (QSA) ELSs are not supported on F_Port trunks.
Supported on F_Port master trunk.
F_Port masterless trunking is only supported in the CORE PID format.
Port mirroring is not supported on Trunk Area ports or on the PID of an F_Port trunk
port.
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.
Only F_Port trunk ports are allowed on a Trunk Area port. All other port types are
persistently disabled.
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 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 has 0x2f or 0x25 as the
first byte of the PWWN. The TA is part of the PWWN in the format listed in
on page 434.
Not currently supported.
Routing will route against the F_Port trunk master. Port and exchange-based routing
is supported on the F_Port trunk masters. Bandwidth information will be modified
accordingly as the F_Port trunk forms.
The switchCfgTrunk 0 command will fail if a port has TA enabled. All ports on a
switch must be TA-disabled first.
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.
No more than one trunk master in a trunk group. The second trunk master will be
persistently disabled with reason "Area has been acquired".
You must first enable Trunking on the port before the port can have a Trunk Area
assigned to it.
Two masters are not supported in the same F_Port trunk group.
There are no limitations on upgrading to Fabric OS v6.4.0 if the F_Port is present on
the switch. Upgrading is not disruptive.
