random-detect dscp
random-detect dscp
To change the minimum and maximum packet thresholds for the differentiated services code point
(DSCP) value, use the random-detect dscp command in interface or QoS policy-map class
configuration mode. To return the minimum and maximum packet thresholds to the default for the DSCP
value, use the no form of this command.
random-detect dscp dscp-value min-threshold max-threshold [max-probability-denominator]

Command History
dscp-value DSCP value. The DSCP value can be a number from 0 to 63, or it
can be one of the following keywords: af11, af12, af13, af21, af22,
af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3, cs4, cs5, cs7,
ef, or rsvp.
min-threshold Minimum threshold in number of packets. The value range of this
argument is from 1 to 4096. When the average queue length reaches
the minimum threshold, Weighted Random Early Detection
(WRED) or distributed WRED (dWRED) randomly drops some
packets with the specified DSCP value.
max-threshold Maximum threshold in number of packets. The value range of this
argument is from the value of the min-threshold argument to 4096.
When the average queue length exceeds the maximum threshold,
WRED or dWRED drops all packets with the specified DSCP value.
max-probability-denominator (Optional) Denominator for the fraction of packets dropped when
the average queue depth is at the maximum threshold. For example,
if the denominator is 512, 1 out of every 512 packets is dropped
when the average queue is at the maximum threshold. The value
range is from 1 to 65536. The default is 10; 1 out of every 10 packets
is dropped at the maximum threshold.
