F_Port masterless trunking

NOTE
You do not need to manually map the host to the master port because Access Gateway will perform
a cold failover to the master port.

To implement F_Port masterless trunking, you must first configure an F_Port trunk group and
statically assign an Area_ID within the trunk group. Assigning a Trunk Area (TA) to a port or trunk
group enables F_Port masterless trunking on that port or trunk group.

You cannot create a Trunk Area on ports with different Admin Domains. You cannot

Area assignment
You statically assign the area within the trunk group on the edge switch. That group
is the F_Port masterless trunk.

The static trunk area you assign must fall within the ASIC's trunk group of the switch

Authentication
Authentication occurs only on the F_Port trunk master port and only once per the
entire trunk. This behavior is the same as E_Port trunk master authentication.
Because only one port in the trunk does FLOGI to the switch, and authentication
follows FLOGI on that port, only that port displays the authentication details when
you issue the portShow command.

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.
