2 PortCfgQos PortCfgQos Synopsis Enables or disables QoS, sets the default configuration, and sets and resets the ingress rate limit. portcfgqos --default | --disable | --enable [slot/]port portcfgqos --setratelimit [slot /]port ratelimit portcfgqos --resetratelimit [slot/]port portcfgqos --help Description Use this command to enable or disable Adaptive Networking/Quality of Service (AN/QoS) on a port, to set or reset the ingress rate limit for the specified port, and to set the default behavior. The Adaptive Networking with QoS feature allows latency-sensitive applications to share 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 proactively avoided. Notes The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command Availability" for details. An Adaptive Networking license is required for using the QoS feature. The QoS configuration of a port is applicable to that port only when it comes up as an E_Port to form an interswitch link (ISL). QoS configuration is persistent across system reboots. Operands This command has the following operands: slot For bladed systems only, specify the slot number of the port to configure, followed by a slash (/). port Specify a port number to configure, relative to its slot for bladed systems. Use switchShow to display a list of valid ports. This operand is optional; if omitted, this command displays the persistently enabled condition for all ports. --default Applies the default QoS configuration to the specified ports. QoS is enabled by best effort based on availability of buffers. --disable Disables QoS configuration on the specified ports. --enable Enables QoS configuration on the specified ports. --resetratelimit Turns off the ingress rate limiting feature on the specified ports. --setratelimit Sets an ingress rate limit to reduce traffic fromthe specified ports. This configuration is applicable only to F/F_Ports. For E/EX_Ports, this configuration would not be effective. The ingress rate limit is enforced only when a given port can run at a speed higher than the speed specified in the configuration. For example if the rate limit is set at 4 Gbps and the port comes online only at 2 Gbps, no enforcement is needed. Specify an ingress rate in Mbps. Supported values for --setratelimit are: 200, 400, 600, 800, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 5000, 6000, 7000, 8000. --help Displays command usage. 576 Fabric OS Command Reference 53-1001186-01
