Configuring a QoS policy

You can configure QoS by using the MQC approach or non-MQC approach. Some features support
both approaches, but some support only one.

Non-MQC approach

In the non-MQC approach, you configure QoS service parameters without using a QoS policy. For
example, you can use the rate limit feature to set a rate limit on an interface without using a QoS
policy.

MQC approach

In the modular QoS configuration (MQC) approach, you configure QoS service parameters by using
QoS policies. A QoS policy defines the shaping, policing, or other QoS actions to take on different
classes of traffic. It is a set of class-behavior associations.
A traffic class is a set of match criteria for identifying traffic, and it uses the AND or OR operator.
•
If the operator is AND, a packet must match all the criteria to match the traffic class.
•
If the operator is OR, a packet matches the traffic class if it matches any of the criteria in the
traffic class.
A traffic behavior defines a set of QoS actions to take on packets, such as priority marking and
redirect.
By associating a traffic behavior with a traffic class in a QoS policy, you apply QoS actions in the
traffic behavior to the traffic class.
