HP HSR6800 Command Reference Manual page 131

Default command level
2: System level
Parameters
dscp: Uses DSCP for calculating drop probability for a packet.
ip-precedence: Uses IP precedence for calculating drop probability for a packet. If neither dscp nor
ip-precedence is specified, IP precedence applies by default.
Usage guidelines
You can configure a WRED drop action only after you have configured the queue af command or the
queue wfq command. The WRED settings in QoS policies override the WRED settings directly configured
on interfaces.
Examples
# Configure IP precedence-based WRED in traffic behavior database.
<Sysname> system-view
[Sysname] traffic behavior database
[Sysname-behavior-database] queue wfq
[Sysname-behavior-database] wred
