Comware QoS Policy

QoS Policy

Configuring a VoIP QoS policy

Follow these steps to configure and use a QoS policy:

1. Create a class and define a set of match criteria in class view.

2. Create a traffic behavior and define a set of QoS actions in traffic behavior view.

3. Create a policy and associate the traffic behavior with the class in policy view.

4. Apply the QoS policy.

1. Defining a class

# Create a class named AutoQoS-VoIP-Control-Trust and enter its view.

# Define a match criterion for class AutoQoS-VoIP-Control-Trust to match the packets with a DSCP value of 24 or 26.

[H3C] traffic classifier AutoQoS-VoIP-Control-Trust operator or

[H3C-classifier-AutoQoS-VoIP-Control-Trust] if-match dscp 24 26 (cs3 or af31)

# Create a class named Auto AutoQoS-VoIP-RTP-Trust and enter its view.

# Define a match criterion for class AutoQoS-VoIP-RTP-Trust to match the packets with a DSCP value of 46

[H3C] traffic classifier AutoQoS-VoIP-RTP-Trust

[H3C-classifier-AutoQoS-VoIP-RTP-Trust] if-match dscp 46 (ef)

2. Defining a traffic behavior

To define a traffic behavior, you must first create a traffic behavior name and then configure attributes in traffic behavior view. A behavior is a set of QoS actions.

# Create name remark_to_ef and Set the DSCP value of packets to 46 (ef)

[H3C] traffic behavior  remark_to_ef

[H3C-behavior-remark_to_ef] remark dscp 46

# Create name remark_to_cs3 and Set the DSCP value of packets to 26 (cs3)

[H3C] traffic behavior remark_to_cs3

[H3C-behavior-remark_to_cs3] remark dscp 26

3. Defining a policy

A policy defines the mapping between a class and a traffic behavior. In a policy, multiple class-to-traffic-behavior mappings can be configured, and these mappings are executed according to the order configured.
