Parameter

queue-length: Maximum threshold value of the queue in the range of 1 to 1024. The default drop mode is tail drop.

Description

Using queue-lengthcommand, you can configure maximum queue length. Using undo queue-lengthcommand, you can delete configuration.

This command can be used only after the af or wfq command is configured.

If you run the undo af command after configuring the queue-lengthcommand, the latter will be deleted at the same time.

After configuring queue-length, if you enable random drop with the wred command, the former will be canceled.

By default, tail drop is configured.

For the related command, see qos policy, qos-class.

Example

Configure tail drop and the maximum queue length as 16.
