Chapter 52 Configuring QoS
Configuring QoS on the Switch
Threshold 1 is the lowest-priority threshold. The priority increases with the threshold number.
This example shows how to associate the CoS value 3 to threshold 2:
Console> (enable) set qos map 1q8t rx 1 2 cos 3
QoS rx priority queue and threshold mapped to cos successfully.
Console> (enable)
1q2t Receive Queues
To associate the CoS values to the 1q2t receive-queue drop thresholds, perform this task in privileged
mode:
Threshold 1 is the low-priority threshold. Threshold 2, which is the high-priority threshold, is not
configurable.
This example shows how to associate the CoS value 3 to threshold 1:
Console> (enable) set qos map 1q2t rx 1 1 cos 3
QoS rx priority queue and threshold mapped to cos successfully.
Console> (enable)
1p1q4t Receive Queues
To associate the CoS values to the 1p1q4t receive-queue drop thresholds, perform this task in privileged
mode:
Queue 1 is the standard queue. Queue 2 is the strict-priority queue.
The threshold numbers range from 1 for low priority to 4 for high priority.
This example shows how to associate the CoS value 5 to the strict-priority receive-queue 2/threshold 1:
Console> (enable) set qos map 1p1q4t rx 2 1 cos 5
Qos rx strict queue and threshold mapped to cos successfully.
Console> (enable)
Task Command
Step 1
Associate the CoS value to a receive-queue drop
threshold.
set qos map 1q2t rx 1 1 cos coslist
Step 2
Verify the configuration. show qos info config 1q2t rx
Task Command
Step 1
Associate the CoS value to a receive-queue drop
threshold.
set qos map 1p1q4t rx q# thr# cos coslist
Step 2
Verify the configuration. show qos info config 1p1q4t rx
