if-match ip-precedence

Function

The if-match ip-precedence command configures a matching rule based on the IP precedence of packets in a traffic classifier.

The undo if-match ip-precedence command deletes a matching rule based on the IP precedence of packets in a traffic classifier.

By default, a matching rule based on the IP precedence of packets is not configured in a traffic classifier.

Format

if-match ip-precedence ip-precedence-value &<1-8>

undo if-match ip-precedence

Parameters

Parameter	Description	Value
ip-precedence-value	Specifies the IP precedence.	The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority of packets.

Views

Traffic classifier view

2: Configuration level

Usage Guidelines

Usage Scenario

You can run the if-match ip-precedence command to classify packets based on the IP precedence so that the device processes packets matching the same traffic classifier in the same manner.

Prerequisites

A traffic classifier has been created using the traffic classifier command in the system view.

Precautions

After the if-match ip-precedence command is run, IP precedences are listed in ascending order.

If you enter multiple IP precedences in the if-match ip-precedence command, a packet matches a rule as long as it matches one of the IP precedence values, regardless of whether the relationship between traffic classification rules is AND or OR.

In a traffic classifier where the relationship between rules is AND, the if-match dscp and if-match ip-precedence commands cannot be used simultaneously.

If you run the if-match ip-precedence command in the same traffic classifier view multiple times, only the latest configuration takes effect.

Example

# Configure a matching rule based on the IP precedence of 1 in the traffic classifier class1.

<HUAWEI> system-view
[HUAWEI] traffic classifier class1
[HUAWEI-classifier-class1] if-match ip-precedence 1
