Trunking in Access Gateway mode

Table 9 describes the PWWN format for F_Port and N_Port trunk ports.
Trunking considerations for Access Gateway mode
Consider the following for trunking in Access Gateway mode:
• Access Gateway trunking is not supported on M-EOS or third-party switches.
• Trunk groups cannot span across multiple N_Port groups within an AG module in AG mode.
Multiple trunk groups are allowed within the same N_Port group. 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.
• The ag -wwnmapshow command will not display trunking for device-mapped ports. If a device
is mapped to a port with device mapping and that port is currently part of a trunk, then the
device will use that trunk. When trunking is used with the Device Load Balancing policy, then
the load on each trunk will be proportional to the number of ports in that trunk. Use the ag
-show command to determine the devices using a particular trunk.
Upgrade and downgrade considerations for trunking in Access Gateway
mode
Upgrading to Fabric OS v7.0.0 and downgrading to Fabric OS v6.4.0 and earlier is supported.
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.
