4. Configure the Scheduler Mode for the CoS Queues
This step enables strict priority scheduling on one or more CoS queues
(traffic classes). Strict priority scheduling ensures that packets assigned to a
higher CoS queue number are serviced before packets assigned to lower CoS
queue numbers. The strict priority setting does not restrict frame ingress. Use
the 'no' command to disable strict priority mode scheduling.
It is recommended that all queues enabled for strict priority scheduling be
assigned to a single strict-priority-enabled TCG other than TCG0.
The following example sets CoS queue (traffic class) number 3 to be serviced
with strict priority:
console(config-if-Te1/0/1)#cos-queue strict 3
To show the minimum bandwidth and scheduler modes for CoS queues, use
the following command.
console#show interfaces cos-queue tengigabitethernet 1/0/1
Interface...................................... Te1/0/1
Interface Shaping Rate......................... 0 kbps
WRED Decay Exponent............................ 9
Queue Id Min. Bandwidth

0 20
1 35
2 35

4 0
5 0
6 0
5. Map the CoS Queues to TCGs
In this step, CoS queues are mapped to Traffic Class Groups (TCGs). Since
TCGs are serviced from highest numbered TCG to lowest, higher priority
traffic should be assigned to higher numbered TCGs. In general, strict
priority traffic (typically control plane or low bandwidth, low latency traffic) is
assigned the highest numbered TCG. It is recommended that WDRR queues
be assigned to TCG0.
