QoS configuration approaches
Overview
You can configure QoS in these approaches:
•
•
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.
