# Define a traffic behavior, and enable EF and set a maximum bandwidth percentage of 30% (both

bandwidth and delay are guaranteed for EF traffic) in the traffic behavior.

# Define a QoS policy and associate the configured traffic behaviors with classes in the QoS policy.

# Apply the QoS policy to the outgoing traffic of GigabitEthernet 2/1/0.

[RouterA] interface gigabitethernet 2/1/0

[RouterA-GigabitEthernet2/1/0] ip address 1.1.1.1 255.255.255.0

[RouterA-GigabitEthernet2/1/0] qos apply policy dscp outbound

The configuration enables EF traffic to be forwarded preferentially when congestion occurs.

Configuring packet information pre-extraction

If a tunnel 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 obtain the IP information of the original packets.

To process the original IP packets with QoS on the physical interface for a tunnel 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 tunnel interface view.

interface tunnel interface-number N/A

3. Enable packet information

pre-extraction on the tunnel

interface.

qos pre-classify

By default, packet information

pre-extraction is disabled on a

tunnel interface.

Configuration example
