Access Gateway trunking considerations for the Edge switch (Continued)TABLE 10
Category Description
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.

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 Gatewaymode
Upgrading to Fabric OS v7.1.0 and downgrading to Fabric OS v6.4.0 and earlier is supported.
