Table 11

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

Adaptive Networking on Access Gateway

Adaptive Networking (AN) services ensure bandwidth for critical servers, virtual servers, or
applications in addition to reducing latency and minimizing congestion. Adaptive Networking in
Access Gateway works in conjunction with the Quality of Service (QoS) feature on Brocade fabrics.
Fabric OS provides a mechanism to assign traffic priority, (high, medium, or low) for a given source
and destination traffic flow. By default, all flows are marked as medium.

You can configure the ingress rate limiting and SID/DID traffic prioritization levels of QoS for the
following configurations:

Supported HBA to AG to switch

Unsupported HBA to AG to switch

HBA (all) to Edge AG to Core AG to switch

For additional information on the QoS feature for Brocade adapters, refer to the Brocade Adapters
Administrator's Guide.
