Modular QoS CLI

• The MQC provides a modular approach to configuration of QoS mechanisms.

First, build modules defining classes of traffic.

Then, build modules defining QoS policies and assign classes to policies.

Finally, assign the policy modules to interfaces.

The MQC was introduced to allow any supported classification to be used with any QoS mechanism.

The separation of classification from the QoS mechanism allows new Cisco IOS versions to introduce new QoS mechanisms and reuse all available classification options. On the other hand, old QoS mechanisms can benefit from new classification options.

Another important benefit of the MQC is the reusability of configuration. MQC allows the same QoS policy to be applied to multiple interfaces. The MQC, therefore, is a consolidation of all the QoS mechanisms that have so far only been available as standalone mechanisms.
