QoS Policy Overview A QoS policy includes three elements: class, traffic behavior, and policy. You can
bind the specified class to a traffic behavior through the QoS policy so as to
configure QoS conveniently.
Class
A class is used to identify traffic.
Class elements include class name and rule.
You can define a series of rules by executing some commands to classify packets.
Also you can use commands to specify the relationship between rules: and and or.
■ and: The device considers a packet belongs to a class only when the packet
matches all rules.
■ or: The device considers a packet belongs to a class as long as the packet
matches one of the rules in the class.
Traffic behavior
A traffic behavior is used to define QoS actions conducted for packets.
Traffic behavior elements include traffic behavior name and actions defined in the
traffic behavior.
Users can use commands to define multiple actions in a traffic behavior.
Policy
A policy is used to bind a specific class to a specific traffic behavior.
Policy elements include policy name and name of the bound class and traffic
behavior.
