PortCfgQoS

PortCfgQoS
Enables or disables QoS, sets the default configuration, and sets and resets the ingress rate limit.
Synopsis portcfgqos --disable | --enable | --default [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 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 this command.
This command is not supported on all platforms. Refer to the Fabric OS Administrator's Guide for
more information.
The configuration changes effected by this command are persistent across system reboots.
The Fabric OS port configuration commands are not supported on FCoE ports.
Operands This command has the following operands:

For bladed systems only, specifies the slot number of the port to configure,
followed by a slash (/).
Specifies the port to be configured, relative to its slot for bladed systems. Use
switchShow for a listing of valid ports.
Applies the default QoS configuration to the specified ports. This command
attempts to enable QoS; success depends on availability of buffers.
Disables the QoS configuration on the specified port. Qos is by default
enabled.
Enables the QoS configuration on the specified port.
Turns off the ingress rate limiting feature on the specified port.
Sets an ingress rate limit to reduce traffic from the specified port. This
configuration is applicable only to F/FL_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
