R3303-HP HSR6800 Routers ACL and QoS Configuration Guide

Configuring packet information pre-extraction

On a logical interface, such as a tunnel, RPR logical, Layer 3 aggregate, or HDLC link bundle interface,

if the interface has processed the incoming IP packets, for example, if the tunnel interface has used GRE

to encapsulate packets, the GRE-encapsulated packets enter the QoS module for processing. As a result,

the QoS module cannot get the IP information of the original packets.

To process the original IP packets with QoS on the physical interface for a logical interface, configure

packet information pre-extraction on the logical interface.

Configuration procedure

To configure packet information pre-extraction:

Ste

Command Remarks

1. Enter system view.

system-view N/A

2. Enter interface view.

• interface tunnel interface-number

• interface rpr interface-number

• interface route-aggregation { interface-number

| interface-number.subnumber }

• interface hdlc-bundle bundle-id

Use any of the commands.

Support for interface types

depends on your device

model.

3. Enable packet

information

pre-extraction.

qos pre-classify

By default, packet

information pre-extraction

is disabled.
