Access Gateway N_Port trunking

portCfgTrunkPort <port>, 0 portCfgTrunkPort <port>, 0 will fail if a Trunk Area is enabled on a
port. The port must be Trunk Area disabled first.
switchCfgTrunk 0 switchCfgTrunk 0 will fail if a port has TA enabled. All ports on a
switch must be TA disabled first.
Port Swap 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 No more than one trunk master in a trunk group. The second
trunk master will be persistently disabled with reason "Area has
been acquired”.
Fast Write When you assign a Trunk Area to a trunk group, the trunk group
cannot have fast write enabled on those ports; if a port is fast
write enabled, the port cannot be assigned a Trunk Area.
FICON 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.
FC8-48 and FC4-48C blades F_Port masterless trunking is supported on ports 16-43 on the
FC8-48 blade. On the FC8-48 and FC4-48C blades F_Port
trunking supported only on ports 0 - 15.
FC4-32 blade If an FC4-32 (Electron) blade has the Trunk Area enabled on ports
16 - 31 and the blade is swapped with an FC4-48C and 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.
Trunking You must first enable Trunking on the port before the port can
have a Trunk Area assigned to it.
PID format F_Port masterless trunking is only supported in CORE PID format.
Long Distance 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 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.
Note: Configurations that are not compatible with F_Port trunking
are long distance, port mirroring, non-CORE_PID, and fastwrite.
ICL Port F_Port trunks are not allowed on ICL Ports. The porttrunkarea
command does not allow it.
AD You cannot create a Trunk Area on ports with different Admin
Domains. You cannot create a Trunk Area in AD255.
