Q Commands
The commands in this chapter apply to the Cisco MDS 9000 Family of multilayer directors and fabric switches. All commands are shown here in alphabetical order regardless of command mode. See the "Command Modes" section to determine the appropriate mode for each command. For more information, refer to the Cisco MDS 9000 Family Configuration Guide.
qos class-map
To create and define a traffic class with match criteria that will be used to identify traffic, use the qos class-map command in configuration mode. To remove a previously-configured class, use the no form of the command.
qos class-map class [match-all | match-any]
no qos class-map class
Syntax Description
Defaults
match-all
Command Modes
Configuration mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
You can access this command only if you enable the QoS data traffic feature using the qos enable command.
Examples
The following example shows how to create a QoS class map and enter class map configuration mode.
switch# config tswitch(config)# qos class-map MyClass1switch(config-cmap)#Related Commands
qos control priority
To enable the QoS priority assignment for control traffic feature on the Cisco MDS 9000 family of switches, use the qos control command in configuration mode. To revert to the factory default, use the no form of the command.
qos control priority 0
no qos priority control 0
Syntax Description
Defaults
Enabled and priority 7 are the defaults.
Command Modes
Configuration mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
None.
Examples
The following example sets the QoS priority assignment to the highest level.
switch# config tswitch(config)# no qos control priority 0Related Commands
qos enable
To enable the QoS priority assignment for data traffic feature on the Cisco MDS 9000 family of switches, use the qos enable command in configuration mode. To disable the QoS priority assignment for control traffic feature, use the no form of the command.
qos enable
no qos enable
Syntax Description
This command has no arguments or keywords.
Defaults
Disabled.
Command Modes
Configuration mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.3(1).
Usage Guidelines
None.
Examples
The following example disables the QoS priority assignment feature.
switch# config tswitch(config)# qos enableRelated Commands
qos dwrr-q
To associate a weight with a deficit weighted round robin (DWRR) scheduler queue, use the qos dwrr-q command in configuration mode. To remove a previously-configured class, use the no form of the command.
qos dwrr-q {high | low | medium} weight value
no qos dwrr-q {high | low | medium} weight value
Syntax Description
Defaults
10
Command Modes
Configuration mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.3(1).
Usage Guidelines
You can access this command only if you enable the QoS data traffic feature using the qos enable command.
Examples
The following example specifies the DWRR queue priority.
switch# config tswitch(config)# qos dwrr-q high weight 50The following example reverts to the default value of 10.
switch(config)# no qos dwrr-q high weight 50Related Commands
qos policy-map
To specify the class of service, use the qos policy-map command in configuration mode. To remove a previously-configured class, use the no form of the command.
qos policy-map policy-name -->
class class-name -->
dscp dscp-value
priority {high | low | medium}no qos policy-map policy-name -->
no class class-name -->
no dscp dscp-value
no priority {high | low | medium}Syntax Description
Defaults
The default DSCP value is 0.
The default priority is low.
Command Modes
Configuration mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.3(1).
Usage Guidelines
You can access this command only if you enable the QoS data traffic feature using the qos enable command.
As an alternative, you can map a classmap to a Differentiated Services Code Point (DSCP).The DSCP is an indicator of the service level for a specified frame. The DSCP value ranges from 0 to 63. A dscp value of 46 is disallowed.
Examples
The following example creates a policy map called MyPolicy and places you in the policy-map submode.
switch(config)# qos policy-map MyPolicyswitch(config-pmap)#The following example deletes the policy map called OldPolicy and places you in the policy-map submode.
switch(config)# no qos policy-map OldPolicyswitch(config)#The following example specifies the name of a predefined class and places you at the policy-map submode for that class.
switch(config-pmap)# class MyClassswitch(config-pmap-c)#The following example exits the policy-map submode for this class.
switch(config-pmap)# no class OldClassThe following example specifies the DSCP value to mark each frame matching this class.
switch(config-pmap-c)# dscp 2Operation in progress. Please check class-map parametersThe following example deletes a previously-assigned DSCP value.
switch(config-pmap-c)# no dscp 60Related Commands
qos service
To apply a service policy, use the qos service command in configuration mode. To remove a previously-configured class, use the no form of the command.
qos service policy policy-name vsan vsan-id
no qos service policy policy-name vsan vsan-id
Syntax Description
policy policy-name
Associates a policy map with the VSAN.
vsan vsan-id
