random-detect
To configure weighted random early detection (WRED) on both ingress and egress queues by setting
aggregate minimum and maximum packet drop threshold default values for specific class of service
(CoS) values, use the random-detect command. To remove a WRED configuration, use the no form of
this command.
Syntax Description
cos cos-list
minimum-
threshold
min-threshold
packets

maximum-
threshold
max-threshold

-qsize
Defaults Thresholds are in packets by default.
The random-detect cos-based command must be specified for a queue to establish default thresholds
for any CoS values that are not specified in random-detect commands for the same queue.

minimum guaranteed link rate.
Specifies the percentage of the threshold.
Minimum percentage of the buffer memory used by the queue. Valid values are
from 1 to 100.
(Optional) Specifies the maximum threshold.
Maximum threshold. Valid values are from 1 to 52428800.
(Optional) Maximum percentage of the buffer memory used by the queue. Valid
values are from 1 to 100.
