Access Gateway trunking considerations for the Edge switch (Continued)TABLE 10
Category Description
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.
FC4-32 blade If an FC4-32 blade has the Trunk Area enabled on ports 16 - 31 and the blade is
swapped with a 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 when AG is enabled on a switch. This means 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.
Port speed Ports within a trunk must have the same port speed for a trunk to successfully be
created.
configDownload and
configUpload
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 Fast Write.
If you issue the configupload command, consider the following:
• ‐ A configuration file uploaded when AG mode is disabled cannot be
downloaded when AG mode is enabled.
‐ A configuration file uploaded when AG mode is enabled cannot be
downloaded when AG mode is disabled.
‐ A configuration file uploaded when the PG policy is enabled cannot be
downloaded when the APC policy is enabled.
‐ A configuration file uploaded when the APC policy is enabled cannot be
downloaded when the PG policy is enabled.
ICL port F_Port trunks are not allowed on ICL ports. The porttrunkarea command does not
allow it.
