Parameters
dscp-value: Specifies a DSCP value in the range of 0 to 63. This argument can also be represented
by using one of the keywords listed in
low limit low-limit: Specifies the lower WRED limit (in packets) in the range of 1 to 1024.
high-limit high-limit: Specifies the upper WRED limit (in packets) in the range of 1 to 1024.
discard-probability discard-prob: Specifies the denominator for drop probability calculation, in the
range of 1 to 255.
Usage guidelines
Before configuring this command, enable DSCP-based WRED on the interface with the qos wred
dscp enable command. The upper and lower limits restrict the average queue length.
Examples
# Configure the following parameters for packets with DSCP value 63 on GigabitEthernet 2/1/1:
lower limit 20, upper limit 40, and drop probability denominator 15.
