Trunking in Access Gateway mode
3
Trunk area
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.
PWWN
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
Downgrade
You can have trunking on, but you must disable the trunk ports
before performing a firmware downgrade.
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.
Upgrade
No limitations on upgrade to Fabric OS v6.4.0 if the F_Port is
present on the switch. Upgrading is not disruptive.
HA Sync
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.
Port Types
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.
Default Area
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
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 blades
F_Port Trunking does not support shared area ports on the
Brocade FC8-48 blades in a 48000. F_Port Trunking is supported
on all ports on the Brocade FC8-48 in the DCX and DCX-4S.
