Configuring a QoS policy
A QoS policy defines what QoS actions to take on what class of traffic for purposes such as traffic
shaping or traffic policing. Before configuring a QoS policy, be familiar with these concepts:
• Class
Classes identify traffic.
A class is identified by a class name and contains some match criteria for identifying traffic. The
relationship between the criteria can be AND or OR.
AND —A packet is considered belonging to a class only when the packet matches all the criteria
in the class.
OR —A packet is considered belonging to a class if it matches any of the criteria in the class.
• Traffic behavior
A traffic behavior, identified by a name, defines a set of QoS actions for packets.
•
Policy
A policy associates a class with a traffic behavior to define what actions to take on which class of
traffic.
You can define multiple class-traffic behavior associations in a policy.
You can apply a policy to a port to regulate traffic sent or received on the port. A QoS policy can
be applied to multiple ports, but in one direction (inbound or outbound) of a port, only one QoS
policy can be applied.
