Trunking in Access Gateway mode
3
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 Fastwrite.
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 requests 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.
