Description Use the qos wred apply command to apply WRED table on an interface.

Use the undo qos wred apply command to restore the default dropping method. This command also deletes the application of WRED table.

By default, the dropping method of a queue is tail drop.

The queue-based WRED table can be applied only on a Layer 2 interface and on a layer 2 interface only the queue-based WRED table can be applied.

Execute the command in interface view, and the setting is valid on the current interface only. Execute the command in interface group view, and the setting is valid on all interfaces in the interface group.

Parameters queue-value: Queue number, which is applicable to L2 port only. It ranges from 0 to 3.

low-limitlow-limit: Lower threshold, in the range 1 to 128. It defaults to 10.

discard-probabilitydiscard-prob: Denominator of drop probability; each drop level has an independent drop probability denominator. It ranges from 1 to 16 and defaults to 10.

Description Use the queue command to edit the content of the queue-based WRED table.

Use the undo queue command to restore the content to be default value.

By default, the queue-based WRED global table has a set of usable default parameters. Therefore, there are no default values for the parameters during editing. As long as no value is specified, the default values keep unchanged.
