PortCfgQos

PortCfgQos
Enables or disables QoS, sets the default configuration, and sets and resets the ingress rate limit.
Synopsis 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, a feature available in
the Condor2/Goldeneye 2 ASIC, allows the ASIC to delay 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 Admin Domain restrictions that may be in place. Refer
to chapter1, "Understanding Admin Domain Restrictions" 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 inter-switch link (ISL).
QoS configuration is persistent across system reboots.
Operands This command has the following operands:
slot
port
--default
--disable
--enable
--resetratelimit
--setratelimit
462
For bladed systems only, specify the slot number of the port to configure,
followed by a slash (/).
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.
Applies the default QoS configuration to the specified ports. QoS is enabled
by best effort based on availability of buffers.
Disables QoS configuration on the specified ports.
Enables QoS configuration on the specified ports.
Turns off the ingress rate limiting feature on the specified ports.
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.
