high-limit: Upper threshold value in the range of 1 to 1024. It is 30 by default.

discard-prob: Denominator of drop proportion in the range of 1 to 255. It is 10 by default.

Description

Using wred ip-precedencecommand, you can set precedence lower-limit, upper-limit and drop proportion denominator of WRED. Using undo wred ip-precedencecommand, you can remove the configuration.

This command can be used only after the wred command has been used to enable WRED drop mode based on DSCP. The configuration of wred will be deleted if the configuration of qos wred is deleted.

The configuration of drop parameters will be deleted if af is deleted.

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

Example

Set lower-limit to 20, upper-limit to 40 and discard probability to 15 for the packet with the precedence 3.
