Configuring QoS
1p3q1t Transmit Queues
With 1p3q1t transmit queues, you can associate a CoS value with either the nonconfigurable tail-drop
threshold or the configurable WRED-drop threshold:
•
•
To associate CoS values to the 1p3q1t transmit-queue drop thresholds, perform this task in privileged
mode:
Task
Step 1
Associate a CoS value to a transmit-queue drop
threshold.
Step 2
Verify the configuration.
Queue 1 is standard low priority, queue 2 is medium priority, and queue 3 is high priority. Queue 4 is
strict priority.
To map CoS values to the tail-drop threshold, omit the threshold number or enter 0.
The WRED-drop threshold number is 1.
This example shows how to associate the CoS value 0 to transmit-queue 1/drop threshold 1:
Console> (enable) set qos map 1p3q1t tx 1 1 cos 0
Qos tx strict queue and threshold mapped to cos successfully.
Console> (enable)
Reverting to CoS Map Defaults
To revert to default CoS value/drop threshold mapping, perform this task in privileged mode:
Task
Step 1 Revert to QoS map defaults.
Step 2 Verify the configuration.
This example shows how to revert to QoS map defaults:
Console> (enable) clear qos map 1p3q1t tx
Qos map setting cleared.
Console> (enable)

To associate a CoS value with the tail-drop threshold, map the CoS value to the queue.
To associate a CoS value with the WRED-drop threshold, map the CoS value to the queue and
threshold.
