Ingress rate limit

Ingress rate limiting is a licensed feature that requires the Adaptive Networking license.

NOTE

For Brocade 6520, ingress rate limit can be configured without Adaptive Networking (AN) and Server
Application Optimization (SAO) licenses. For other platforms, these licenses are required.

Ingress rate limiting restricts the speed of traffic from a particular device to the switch port,
allowing latency-sensitive applications to share the storage resources alongside
throughput-intensive applications. Ingress rate limiting delays the return of BB credits to the
external device. By limiting the throughput on the ingress side of a port, existing congestion can be
removed or avoided.

The implication is as follows:

Ingress rate limiting is not supported if the F_Port is in AOQ.

Ingress rate limiting is not supported if the F_Port is part of Trunk.

Ingress rate limiting is not supported if the F_Port is not QoS enabled, but it connects to a QoS
enabled AG switch port.

Ingress rate limiting is applicable only to F_Ports and FL_Ports and is available only on the following
platforms:
