undo wred [ ip-dscp ip-precedence ]

View

Policy-class view

Parameter

ip-dscp: Indicate that DSCP value is used when calculating drop proportion for a packet.

ip-precedence: Indicate that IP precedence value is used when calculating drop proportion for a packet. By default, ip-precedenceis configured.

Description

Using wred command, you can configure drop mode as WRED. Using undo wred command, you can delete the configuration.

To use this command, the af command must have been configured. For default-class, the af or wfq command must be configured before using the command.The wred and queue-lengthcommands cannot be configured at a time. When canceling this configuration, the WRED-related configuration will be deleted. When a policy configured with wred is applied on an interface, the previous WRED configuration on interface will become ineffective.

For default-class, only ip-precedencecan be configured.By default, the parameter of wred is ip-precedence.

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

Example

Configure WRED for a behavior named database and drop proportion is calculated by IP precedence.
