Default
By default, this option is disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
When a packet arrives, the current average queue size is calculated by hardware.
If the current average queue size is less than the minimum threshold value of the queue, the arriving
packet is queued. If the current queue length is between the minimum threshold value and the maximum
threshold value of the queue, the packet is either dropped or queued depending on the packet drop
probability. The drop probability is calculated by the following formula.
If the average queue size is greater than the maximum threshold value of the queue, all packets will be
dropped. If the specified profile does not exist, then default setting of the threshold will be associated.
Example
This example shows how to enable the WRED function on eth3/0/1 queue 5 and apply the WRED profile
10.
Switch# configure terminal
Switch(config)# interface eth3/0/1
Switch(config-if)# random-detect 5 profile 10
Switch(config-if)#
116-3 random-detect ecn
This command is used to enable the explicit congestion notification (ECN).Use the no form of the
command to disable it.
