Overview
QoS Feature Configuration with MQC
You use MQC to configure QoS features. The MQC configuration commands are shown in the table below:
Table 2: MQC Configuration Commands
MQC Command
class-map
table-map
policy-map
You can modify or delete MQC objects, except system-defined objects, when the objects are not associated
with any interfaces. For information on system-defined MQC objects, see "Using Modular QoS CLI."
After a QoS policy is defined, you can attach the policy map to an interface by using the interface configuration
command shown in the table below.
Table 3: Interface Command to Attach a Policy Map to an Interface
MQC Command
service-policy
For information on how to use MQC, see "Using Modular QoS CLI."
QoS Statistics
Statistics are maintained for each policy, class action, and match criteria per interface. You can enable or
disable the collection of statistics, you can display statistics using the show policy-map interface command,
and you can clear statistics based on an interface or policy map with the clear qos statistics command. Statistics
are enabled by default and can be disabled globally.
For information about monitoring QoS statistics, see "Monitoring QoS Statistics."
Default QoS Behavior
The QoS queuing features are enabled by default. Specific QoS-type features, policing and marking, are
enabled only when a policy is attached to an interface. Specific policies are enabled when that policy is attached
to an interface.
