Trunking in Access Gateway mode

Disabling F_Port trunking
Use the following steps to disable F_Port Trunking.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the porttrunkarea --disable
command.
switch:admin> porttrunkarea --disable 36-39
ERROR: port 36 has to be disabled
Disable each port prior to removing ports from the TA. Then reissue the command:
switch:admin> porttrunkarea --disable 36-39
Trunk area 37 disabled for ports 36, 37, 38 and 39.
Trunking monitoring
For F_Port masterless trunking, you must install Filter, EE or TT monitors on the F_Port trunk port.
Whenever the master port changes, it is required to move the monitor to the new master port. For
example, if a master port goes down, a new master is selected from the remaining slave ports. APM
must delete the monitor from the old master and install the monitor on new master port. If you
attempt to add a monitor to a slave port, it is automatically added to the master port.
Trunking considerations for the Edge switch
Table 8 describes the Access Gateway trunking considerations for the Edge switch.
TABLE 8 Access Gateway trunking considerations for the Edge switch
Category Description
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 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 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.
Management Server Registered Node ID (RNID), Link Incident Record Registration
(LIRR), and (QSA) Query Security Attributes ELSs are not
supported on F_Port trunks.
