{ and | or } ]
By default, the operator of a class is AND.
The operator of a class can be AND or OR.
• AND—A packet is assigned to a class only when
the packet matches all the criteria in the class.
• OR—A packet is assigned to a class if it matches
any of the criteria in the class.
3. Configure match
criteria.

ACL and QoS Command Reference.
Defining a traffic behavior
A traffic behavior is a set of QoS actions (such as traffic filtering, shaping, policing, and priority marking)
to take on a class of traffic.
The system predefines some traffic behaviors and defines general QoS actions for them. A user-defined
behavior cannot be named the same as a system-defined behavior. You can use these behaviors when
defining a policy. The system-defined behaviors are as follows:
• ef—Expedited forwarding.
• af—Assured forwarding.
• be—Best-effort.
• be-flow-based—Uses the weighted random early detection (WRED) drop policy.
For more information about these system-defined behaviors, see "Configuring congestion management."
To define a traffic behavior:

3. Configure actions in the traffic
behavior.
See the subsequent chapters, depending on the purpose of the traffic
behavior: traffic policing, traffic filtering, traffic redirecting, priority
marking, traffic accounting, and so on.
Defining a policy
You associate a behavior with a class in a QoS policy to perform the actions defined in the behavior for
the class of packets.
You can configure multiple class-behavior associations in a QoS policy, which are matched in the order
they are configured.
The system provides a predefined QoS policy named default. It includes the associations between
predefined classes and predefined traffic behaviors:
• Class ef with behavior ef.
• Classes af1 through af4 with behavior af.
• Class default-class with behavior be.
