Adaptive Networking on Access Gateway

Trunking considerations for Access Gateway mode

Consider the following for Trunking in Access Gateway mode:

Upgrade and downgrade considerations for Trunking in Access Gateway
mode
Upgrading and downgrading from Fabric OS v6.3.0 to Fabric OS v6.2.0 and earlier is supported.
Adaptive Networking on Access Gateway
Adaptive Networking (AN) ensures bandwidth for critical servers, virtual servers, or applications in
addition to reducing latency and minimizing congestion. Adaptive Networking works in conjunction
with the Quality of Service (QoS) feature on Brocade switches. 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.
The following must be appropriately installed:
•
•
To determine if these licenses are installed on the connected switch, issue the Fabric OS
licenseshow command. Refer to the Fabric OS Administrator's Guide for detailed information about
QoS.
You can configure the ingress rate limiting and SID/DID traffic prioritization levels of QoS for the
following configurations:
•
•
•
For additional information on the Brocades adapters, refer to the Brocade Adapters Administrator's
Guide (53-1001256-01).
QoS: Ingress Rate Limiting on AG
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 "QoS: Ingress Limiting" in
the Fabric OS Administrator's Guide.

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 Adaptive Networking (AN) license must be installed on all switches and AGs to take
advantage of the QoS and Ingress Rate Limiting features.
The Server Application Optimization (SAO) license must be installed to extend QoS features to
Brocade HBAs.
