random-detect discard-class
random-detect discard-class
To configure the weighted random early detection (WRED) parameters for a discard-class value for a
class policy in a policy map, use the random-detect discard-class command in QoS policy-map class
configuration mode. To disable the discard-class values, use the no form of this command.
random-detect discard-class value min-threshold max-threshold max-probability-denominator
no random-detect discard-class value min-threshold max-threshold max-probability-denominator
Syntax Description
Command Default For all precedence levels, the max-probability-denominator default is 10 packets; 1 out of every 10
packets is dropped at the maximum threshold.
Command Modes QoS policy-map class configuration
Command History
value Discard class. This is a number that identifies the drop eligibility of a
packet. Valid values are 0 to 7.
min-threshold Specifies the minimum number of packets allowed in the queue. When
the average queue length reaches the minimum threshold, WRED
randomly drops some packets with the specified DSCP, IP
precedence, or discard-class value. Valid minimum threshold values
are 1 to 16384.
max-threshold Specifies the maximum number of packets allowed in the queue.
When the average queue length exceeds the maximum threshold,
WRED drops all packets with the specified DSCP, IP precedence, or
discard-class value. Valid maximum threshold values are 1 to 16384.
max-probability-denominator 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. Valid values are 1 to
65535.
