Configuring packet information pre-extraction

If a tunnel interface has processed an incoming IP packet, for example, if the tunnel interface has used GRE to encapsulate a packet, the GRE-encapsulated packet enters 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.
