Adaptive Networking on Access Gateway 3 Table 11 describes the PWWN format for F_Port and N_Port trunk ports. TABLE 11 PWWN format for F_Port and N_Port trunk ports NAA = 2 2f:xx:nn:nn:nn:nn:nn:nn (1) Port WWNs for: switch FX_Ports. The valid range of xx is [0 - FF], for maximum of 256. NAA = 2 25:xx:nn:nn:nn:nn:nn:nn (1) Port WWNs for: switch The valid range of xx is [0 - FF], FX_Ports for maximum of 256. 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.

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.
