PortCfgQos

PortCfgQos
Enables or disables QoS on a port, 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 ratelimit for the 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 new 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 This command is subject to Admin Domain restrictions that may be in place.
A Brocade 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:
--default
--disable
--enable
--resetratelimit
--setratelimit
--help
Examples To enable QoS on a port:
switch:admin>
To disable QoS on a port:
454
Applies the default Qos configuration to the specified port. QoS will be
enabled by best effort based on availability of buffers.
Disables Qos configuration on the specified port.
Enables Qos configuration on the specified port.
Turns off the ingress rate limiting feature on the specified port.
Sets a ingress rate limit to reduce traffic fromthe specified port. 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.
