Configuring QoS on the Switch
1p2q2t Transmit Queues
To associate the CoS values to the 1p2q2t transmit-queue drop thresholds, perform this task in privileged
mode:
Task
Step 1 Associate the CoS value to a transmit-queue drop
threshold.
Step 2 Verify the configuration.
Queue 1 is standard low priority, queue 2 is high priority, and queue 3 is strict priority.
Threshold 1 is low priority, and threshold 2 is high priority.
This example shows how to associate the CoS value 5 to the strict-priority transmit-queue 3/drop
threshold 1:
Console> (enable) set qos map 1p2q2t tx 3 1 cos 5
Qos tx strict queue and threshold mapped to cos successfully.
Console> (enable)
Associating the 1p1q0t/1p3q1t Ports
On the 1p1q0t/1p3q1t ports, you configure the receive queues and the transmit queues separately.
1p1q0t Receive Queues
To associate the CoS values to the 1p1q0t receive queues, perform this task in privileged mode:
Task
Step 1 Associate the CoS value to a receive queue.
Step 2 Verify the configuration.
Queue 1 is the standard queue, and queue 2 is the strict-priority queue.
This example shows how to associate the CoS value 5 to the strict-priority receive-queue 2:
Console> (enable) set qos map 1p1q0t rx 2 cos 5
QoS queue mapped to cos successfully.
Console> (enable)
1p3q1t Transmit Queues
With the 1p3q1t transmit queues, you can associate a CoS value with either the nonconfigurable
tail-drop threshold or the configurable WRED-drop threshold as follows:

52-70
To associate the CoS value with the tail-drop threshold, map the CoS value to the queue.
To associate the CoS value with the WRED-drop threshold, map the CoS value to the queue and
threshold.
