QoS configuration approaches

Overview

You can configure QoS in these approaches:

Non-policy approach

Policy approach

Some features support both approaches, but some support only one.

Non-policy approach

In non-policy approach, you can configure QoS service parameters directly without using a QoS policy.

For example, you can use the line rate feature to set a rate limit on an interface without using a QoS
policy.

Policy approach

In policy 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 class is a set of match criteria for identifying traffic. It uses the AND or OR operator:

AND—A packet must match all the criteria to match the class.

OR—A packet matches the class if it matches any of the criteria in the 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 class in a QoS policy, you apply the specific set of QoS actions

to the class of traffic.
