Trunking in Access Gateway mode

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.

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.

D,I Zoning
(D,I) AD
(D, I) DCC and (PWWN, I) DCC

Creating a Trunk Area may remove the Index (“I”) from the switch
to be grouped to the Trunk Area. All ports in a Trunk Area share
the same “I”. This means that Domain,Index (D,I), which refers to
an “I”, that might have been removed, will no longer be part of the
switch.

Note: Ensure to include AD, zoning, and DCC when creating a
Trunk Area.

You can remove the port from the Trunk Area to have the “I” back
into effect. D,I will behave as normal, but you may see the effects
of grouping ports into a single “I”.

Also, D,I continues to work for Trunk Area groups. The

“I” can be

used in D,I if the “I” was the “I” for the Trunk Area group.

Note: “I” refers to Index and D,I refers to Domain,Index.

Two masters

Two masters is not supported in the same F_Port trunk group.

QoS

Supported.
