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:
