dscp
dscp
To change the minimum and maximum packet thresholds for the differentiated services code point
(DSCP) value, use the dscp command in random-detect-group configuration mode. To return the
minimum and maximum packet thresholds to the default for the DSCP value, use the no form of this
command.
dscp dscp-value min-threshold max-threshold [mark-probability-denominator]
no dscp dscp-value min-threshold max-threshold [mark-probability-denominator]
Syntax Description
Command Default If WRED is using the DSCP value to calculate the drop probability of a packet, all entries of the DSCP
table are initialized with the default settings shown in Table 2 of the “Usage Guidelines” section.
Command Modes Random-detect-group configuration
Command History
dscp-value Specifies the DSCP value. The DSCP value can be a number from
0 to 63, or it can be one of the following keywords: ef, af11, af12,
af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2,
cs3, cs4, cs5, or cs7.
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) randomly drops some packets with the specified DSCP
value.
max-threshold Maximum threshold in number of packets. The value range of this
argument is the value of the min-threshold argument to 4096. When
the average queue length exceeds the maximum threshold, WRED
drops all packets with the specified DSCP value.
mark-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, one 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; one out of every ten
packets is dropped at the maximum threshold.
