QoS Modular QoS CLI (MQC)

MQC (Modular QoS CLI) is the CLI structure that allows you to enable QoS features in Cisco routers. It uses the following three steps to configure QoS:

  • Define a traffic class with the class-map command.
  • Create a traffic policy by associating the traffic class with one or more QoS features (using the policy-map command).
  • Attach the traffic policy to the interface with the service-policy command.

MQC has largely superseded the use of Multilayer Switch QoS or MLS QoS.
