Parameters
precedence: Specifies an IP precedence value in the range of 0 to 7.
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 drop probability in the range of 1 to 255.
Usage guidelines
Before configuring this command, make sure IP precedence-based WRED is enabled by using the wred
command.
Disabling WRED also removes the wred ip-precedence command configuration.
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 15.
