5 Configuring FC ports • 300, 5300, and 5100 switches • Brocade VA-40FC • Brocade 8000 • Brocade 7800 For non-8 Gbps platforms, all functionality is available without EGM license. 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: • Brocade DCX • Brocade DCX-4S • Brocade DCX 8510 • Brocade Encryption Switch • Brocade 300 • Brocade 5100 • Brocade 5300 • Brocade 5410 • Brocade 5424 • Brocade 5450 • Brocade 5460 • Brocade 5470 • Brocade 5480 • Brocade 6510 • Brocade 6520 • Brocade 7800 66 Web Tools Administrator's Guide 53-1002756-01
