AG trunking considerations for the Edge switch
Table 10
describes the Access Gateway trunking considerations for the Edge switch.
TABLE 10
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 an 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 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.
Note:
Authentication is also supported on switches configured in
AG mode.
Management Server
Registered Node ID (RNID), Link Incident Record Registration
(LIRR), and Query Security Attributes (QSA) Extended Link Service
Requests (ELSs) are not supported on F_Port trunks.
Trunk area
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.
PWWN
The entire Trunk Area trunk group shares the same Port WWN
within the trunk group. The PWWN is the same across the F_Port
trunk that will have 0x2f or 0x25 as the first byte of the PWWN.
The TA is part of the PWWN in the format listed in
Table 11
on
page 65.
Downgrade
You can have trunking on, but you must disable the trunk ports
before performing a firmware downgrade.
Note:
Removing a Trunk Area on ports running traffic is disruptive.
Use caution before assigning a Trunk Area if you need to
downgrade to a firmware earlier than Fabric OS v6.1.0.
Upgrade
No limitations on upgrade to Fabric OS 7.1.0 if the F_Port is
present on the switch. Upgrading is not disruptive.
HA Sync
If you plug in a standby CP with a firmware version earlier than
Fabric OS v6.1.0 and a Trunk Area is present on the switch, the CP
blades will become out of sync.
Port Types
Only F_Port trunk ports are allowed on a Trunk Area port. All other
port types that include F/FL/E/EX are persistently disabled.
