Usage Guidelines

Usage Scenario

The lengths of user packets change after the user packets are processed by a module, which affects traffic shaping precision. To resolve this problem, the network-header-length command can be used to set a network header length for compensating processed packets with a certain length.

Prerequisites

The service-template command has been used to create a service profile.

Precautions

The network-header-length outbound adjust-on-etm command configures a precision compensation value for the eTM module. In the same service template, you can specify precision compensation values for both the non-eTM and eTM modules, which is unnecessary to consider the type of application interface. This command is mutually exclusive with adjust-on-card configured in a QoS profile or interface SQ scenario.

Example

# Set a network header length to 10 for a service profile in the inbound direction.

<HUAWEI> system-view
[~HUAWEI] service-template template1
[*HUAWEI-service-template-template1-slot-all] network-header-length 10 inbound

# Set a network header length to 10 on ETM for a service profile in the inbound direction.

<HUAWEI> system-view
[~HUAWEI] service-template template 1
[*HUAWEI-service-template-template1-slot-all] network-header-length 10 outbound adjust-on-etm
