3.3 Configuring Congestion Management
After congestion management is configured, if congestion occurs on a network, the S3700
determines the sequence of forwarding packets according to the defined scheduling policy.
3.3.1 Establishing the Configuration Task
Before configuring congestion management, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This will help
you complete the configuration task quickly and accurately.

Run the display drop-profile [ all | name drop-profile-name ] command to check the
configuration of the WRED drop profile.
Run the display qos configuration interface interface-type interface-number command
to check all the QoS configurations on the interface.
The same delay and jitter are set for various types of packets, and packets of core services
such as video and voice services need to be processed first.
Packets of non-core services of the same priority, such as email, are processed in a fair
manner, and services of different priorities are processed according to the weights.
Configuring priority mapping based on simple traffic classification
Configuring the remarking action of inner priorities based on complex traffic classification
NOTE
Before configuring congestion management, you need to perform either of the preceding tasks to map
packets to different queues for scheduling.
