2. Create a traffic behavior and
enter traffic behavior view.
traffic behavior behavior-name
The specified traffic behavior name
cannot be the name of any
system-defined behavior.
3. Configure the exponent for WRED
to calculate the average queue
size.
wred weighting-constant
exponent
The default exponent is 9.
Configuring the lower limit, upper limit, and drop probability denominator for each DSCP value in
WRED
To perform this configuration, make sure DSCP-based WRED has been enabled with the wred dscp
command.
Disabling WRED also removes the wred dscp command configuration.
Removing the queue af or queue wfq command configuration also removes the WRED-related
parameters.
To configure the lower limit, upper limit, and drop probability denominator for a DSCP value in WRED:

1. Enter system view.

2. Create a traffic behavior and
enter traffic behavior view.
traffic behavior behavior-name
The specified traffic behavior
name cannot be the name of any
system-defined behavior.
3. Configure the lower limit,
upper limit and drop
probability denominator for a
DSCP value in WRED.
wred dscp dscp-value low-limit
low-limit high-limit high-limit
[ discard-probability discard-prob ]
dscp-value: DSCP value in the
range of 0 to 63, which can also
be any of the following keywords:
ef, af11, af12, af13, af21, af22,
af23, af31, af32, af33, af41,
af42, af43, cs1, cs2, cs3, cs4, cs5,
cs6, cs7, and default.
Configuring the lower limit, upper limit, and drop probability denominator for each IP precedence value
in WRED
To perform this configuration, make sure IP precedence-based WRED has been enabled with the wred
ip-precedence 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.
To configure the lower limit, upper limit, and drop probability denominator for an IP precedence value
in WRED:
