Chapter 3 QoS Policy Configuration

3.1 Overview

QoS policy includes the following three elements: class, traffic behavior and policy. You
can bind the specified class to the specified traffic behavior through QoS policies to
facilitate the QoS configuration.
I. Class
Class is used for identifying traffic.
The elements of a class include the class name and classification rules.
You can use commands to define a series of rules to classify packets. Additionally, you
can use commands to define the relationship among classification rules: and and or.
and: The devices considers a packet to be of a specific class when the packet
matches all the specified classification rules.
or: The device considers a packet be of a specific class when the packet matches
one of the specified classification rules.
II. Traffic behavior
Traffic behavior is used to define all the QoS actions performed on packets.
The elements of a QoS behavior include traffic behavior name and actions defined in
traffic behavior.
You can use commands to define multiple actions in a traffic behavior.
III. Policy
Policy is used to bind the specified class to the specified traffic behavior.
The elements of a policy include the policy name and the name of the
classification-to-behavior binding.

3.2 Configuring QoS Policy

The procedure for configuring QoS policy is as follows:
1) Define a class and define a group of traffic classification rules in class view.
2) Define a traffic behavior and define a group of QoS actions in traffic behavior view.
3) Define a policy and specify a traffic behavior corresponding to the class in policy
view.
4) Apply the QoS policy in Ethernet port view/port group view.
