Access Gateway Trunking Considerations For The Edge Switch; Table 6 Access Gateway Trunking Considerations For The Edge Switch - Brocade Communications Systems A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Trunking prevents reassignments of the Port ID (also referred to as the Address Identifier as
described in
You must install the Brocade ISL license on both the Edge switch and the module running in AG
mode and you must ensure that both modules running Fabric OS v6.1.0 or later.
All ports within a trunk group must be part of the same port group; ports outside of a port group
cannot form a trunk group. For more information on Port Groups, see
page 18.
NOTE
If a switch already has an ISL Trunking license, no new license is required to use it on AG N_Port
masterless trunking; Also, after a trunking license is installed on a switch in AG mode and you
change the switch to standard mode, you can keep the same license. Access Gateway does not work
on M-EOS or third party switches.
To implement F_Port masterless trunking on the Edge switch, 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. When a TA is
assigned to a port or trunk group, the ports will immediately acquire the TA as the area of its
process IDs (PID). And when a TA is removed from a port or trunk group, the port reverts to the
default area as its PID.

Access Gateway trunking considerations for the Edge switch
Description
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 F_Port trunk
group starting from port 0 on a Edge switch or blade.
The static trunk area you assign must be one of the port's default
areas of the trunk group.
Authentication occurs only on the F_Port trunk master port and
only once per the entire trunk. This behavior is 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.
Note: Switches in Access Gateway mode do not perform
authentication.
Registered Node ID (RNID), Link Incident Record Registration
(LIRR), and (QSA) Query Security Attributes ELSs are not
supported on F_Port trunks.
The port must be disabled before assigning a Trunk Area on the
Edge switch to the port or removing a Trunk Area from a trunk
group.
You cannot assign a Trunk Area to ports if the standby CP is
running a firmware version earlier than Fabric OS v6.2.0.
