Access Gateway trunking considerations for the Edge switch (Continued)TABLE 10
Category Description
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.
AD You cannot create a Trunk Area on ports with different Admin Domains. You cannot
create a Trunk Area in AD255.
DCC Policy DCC policy enforcement for the F_Port trunk is based on the Trunk Area; the FDISC
request to a trunk port is accepted only if the WWN of the attached device is part of the
DCC policy against the TA. The PWWN of the FLOGI sent from the AG will be dynamic
for the F_Port trunk master. Because you do not know ahead of time what PWWN AG
will use, the PWWN of the FLOGI will not go through DCC policy check on an F_Port
trunk master. However, the PWWN of the FDISC will continue to go through DCC
policy check.
