Configuring a QoS policy
A QoS policy involves three components: class, traffic behavior, and policy. You can associate a class
with a traffic behavior using a QoS policy.
1) Class
Classes are used to identify traffic.
A class is identified by a class name and contains some match criteria.
You can define a set of match criteria to classify packets. The relationship between criteria can be and
or or.
and: The device considers a packet belongs to a class only when the packet matches all the criteria
in the class.
or: The device considers a packet belongs to a class as long as the packet matches one of the
criteria in the class.
2) Traffic behavior
A traffic behavior, identified by a name, defines a set of QoS actions for packets.
3) Policy
You can apply a QoS policy to a port.
Applies a QoS policy to a port to regulate the inbound traffic of the port. A QoS policy can be applied to
multiple ports. Only one policy can be applied in inbound direction of a port.
