Usage Guidelines

Usage Scenario

If you need to set different upper and lower drop thresholds for packets of different colors in queues, run the port-wred command to create a port-WRED profile.

Configuration Impact

Packets of different colors in port queues are processed based on the upper drop threshold, lower drop threshold, and drop probability in a configured WRED profile.

Follow-up Procedure

Configure an upper drop threshold, a lower drop threshold, and a drop probability, and then apply them to port queues.

Precautions

The system has a default WRED object. If no user-defined WRED object can be used, the default WRED object is used.

Example

# Create a WRED object named pw for a port queue.

[~HUAWEI] port-wred pw
