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
AdaptersAdministrator's Guide .
QoS: Ingress rate limiting
Ingress rate limiting restricts the speed of traffic from a particular device to the switch port. On
switches in AG mode, you must configure ingress rate limiting on F_Ports.
For more information and procedures for configuring this feature, refer to "Ingress Limiting" in the
Fabric OS Administrator’s Guide .
QoS: SID/DID traffic prioritization
SID/DID traffic prioritization allows you to categorize the traffic flow between a given host and target as
having a high or low priority; the default is medium. For example, you can assign online transaction
processing (OLTP) to a high priority and the backup traffic to a low priority.
For detailed information on this feature, refer to "QoS: SID/DID traffic prioritization" in the Fabric OS
Administrator’s Guide.
