Usage Guidelines

Usage Scenario

To perform the traffic policy based on the value of the next IPv6 header, you can run this command to configure a matching rule for complex traffic classification based on the value of the next IPv6 header. Then, you can configure the traffic behavior and traffic policy, and apply the policy to interfaces.

Prerequisites

A traffic classifier is configured in the system view and the traffic classifier view is displayed.

Configuration Impact

The traffic action in the traffic behavior bound to the traffic classifier is performed for the traffic matching the specified value of the next IPv6 header.

Follow-up Procedure

You need to configure the traffic behavior and traffic policy, bind the traffic behavior to the traffic classifier in the traffic policy, and apply the traffic policy to interfaces.

Precautions

You can configure more than one matching rules to match the next IPv6 header in one traffic classifier.

Example

# Define the traffic classifier class1. Set the value of the next IPv6 header matching the traffic classifer class1 to 43.
