(Optional) Configuring a Service Profile
You can configure a network header length in a service profile to compensate a processed packet with the length, precisely controlling traffic.
Context
The length of user packets varies according to the processing mode of the scheduling module, which affects the accuracy of traffic shaping. In this case, you can configure a network header length in a service profile to compensate a processed packet with the length, improving the accuracy of traffic shaping.
Procedure
- Run system-view
The system view is displayed.
- Run service-template service-template-name
The service profile view is displayed.
- Run network-header-length network-header-length { inbound | outbound }
A network header length is configured for the service profile.
To specify network header lengths for both non-eTM and eTM subcards, you must configure them separately in the global service profile. The detailed operations are as follows:
Run the network-header-length network-header-length outbound command in the service profile view to configure a network header length. After the service profile is applied to a QoS profile, the network header length takes effect on a non-eTM subcard in the outbound direction.
- Run the network-header-length network-header-length outbound command in the service profile view to configure a network header length. After the service profile is applied to a QoS profile and the adjust-on-card parameter is specified to make the service profile take effect on an eTM subcard, the network header length takes effect on an eTM subcard in the outbound direction.
- Run the network-header-length network-header-length outbound adjust-on-etm command in the service profile view to configure a network header length in the service profile and make it take effect on an eTM subcard. After the service profile is applied to a QoS profile, the network header length takes effect on an eTM subcard in the outbound direction.
- Run commit
The configuration is committed.
