3 Adaptive Networking on Access Gateway 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 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: • 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. 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: • Brocade HBA to AG to switch • Non-Brocade HBA to AG to switch • HBA (Brocade or non-Brocade) to Edge AG to Core AG to switch 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. 46 Access Gateway Administrator's Guide 53-1001345-01

Adaptive Networking on Access Gateway

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
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:
•
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.
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:
•
Brocade HBA to AG to switch
•
Non-Brocade HBA to AG to switch
•
HBA (Brocade or non-Brocade) to Edge AG to Core AG to switch
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
