Wred Ip-Precedence - H3C SR6600 Command Reference Manual

Removing the wred command configuration removes the wred dscp command configuration as well.
The drop-related parameters are removed if the configuration set with the queue af command or the
queue wfq command is removed.
Related commands: qos policy, traffic behavior, and classifier behavior.
