QoS Commands

Enable WRED on the default CoS 0 queue for unmarked packets and set the 

green, yellow, and red colored traffic to utilize WRED starting at 3% of port 

congestion with a drop probability of 1%, 2% and 3%, respectively. In this 

configuration, non-TCP traffic uses tail-drop queue discipline with a drop 

threshold at 100% of the statically calculated port queue length vs. the 

dynamically calculated value used by the normal tail-drop mechanism 

(approx. 1/2 remaining free memory).

console(config)# cos-queue random-detect 0

console(config)# random-detect queue-parms 0 min-thresh 3 3 

3 100 max-thresh 10 10 10 100 drop-prob-scale 1 2 3 0

Use the cos-queue strict command in either Global Configuration mode or 

Interface Configuration mode to activate the strict priority scheduler mode 

for each specified queue. To restore the default weighted scheduler mode for 

each specified queue, use the no form of this command.

cos-queue strict {

queue-id-1} [{queue-id-2} … {queue-id-n}]

no cos-queue strict {

queue-id-1} [{queue-id-2} … {queue-id-n}]

• queue-id-1 — Specifies the queue ID for which you are activating the 

strict priority scheduler. You can specify a queue ID for as many queues as 

you have (queue-id 1 through queue-id-n). (Range: 0–6)

This command has no default configuration.

Global Configuration mode or Interface Configuration (gigabitethernet, 

port-channel, tengigabitethernet

, fortygigabitethernet) mode
