Software Configuration of ATM ISE Line Cards for Cisco 12000 Series Routers
random-detect dscp
To change the minimum and maximum cell thresholds for the differentiated services code point (DSCP)
value, use the random-detect dscp command in interface configuration mode. To return the minimum
and maximum packet thresholds to the default for the DSCP value, use the no form of this command.

Modification
The cells keyword was added.
This command was introduced.
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.
Minimum threshold in number of cells. The value range of this
argument is from 1 to 262,143. When the average queue length
reaches the minimum threshold, Weighted Random Early Detection
(WRED) randomly drops some packets with the specified DSCP
value.
On the 4-Port ATM ISE line card for the Cisco 12000 Series Router,
the min-threshold and max-threshold values must be specified as a
count of ATM cells.
Maximum threshold in number of cells. The value range of this
argument is from the value of the min-threshold argument to
262143. When the average queue length exceeds the maximum
threshold, WRED drops all packets with the specified DSCP value.
(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 32,768.
For the 4-Port ATM ISE line card, the mark probability
Note
denominator is rounded to the nearest power of 2.
