Usage Guidelines

Usage Scenario

After the WRED objects are configured on port queues, the display port-wred configuration command can be used to check whether the configurations of WRED objects for the port queues are correct.

Prerequisites

The port-wred command has been run to create a WRED object.

Precautions

If the port-wred command has not been run to configure a WRED object, the display port-wred configuration command output will show that the number of WRED objects is 0.

Example

The actual command output varies according to the device. The command output here is only an example.
