Usage guidelines
Before configuring this command, make sure IP precedence-based WRED is enabled by using the
wred command.
The wred ip-precedence command configuration is deleted when the undo wred command is
executed.
Removing the queue af or queue wfq command configuration also removes the WRED-related
parameters.
Examples
# Configure the following parameters for packets with IP precedence value 3: lower limit 20, upper
limit 40, and drop probability denominator 15.
