Hello Rene, Thanks a lot for your explanation. However, still needs some more clarification. Lets’ say I have an interface GIg 0/1 that is capable of handling 100 packets per second. I have three different kinds of traffic passing through the interface. They are Traffic A, B and C. And the QoS is configured like this: Traffic A: Priority 50 packets Traffic B: Bandwidth 25 packets Traffic C: Bandwidth 25 packets I am just using packets per second instead of MB or KB per second. As far as my understanding goes, QoS will work like this: #Every second the interface will send out 100 packets totally, but QoS will make sure that out of those 100 packets, the interface will send 50 packets of Traffic A first and then 25 packets from Traffic B and 25 packets from Traffic C.Is it correct? If I draw this, the queue will be like this: B + C + A =========\>\>Out 25 + 25 + 50 or C + B + A ===========\>Out 25 + 25 + 50 Meaning Traffic A will be delivered first. Is it correct? Thank you so much. Azm --- _[View the full topic](https://forum.networklessons.com/t/qos-llq-low-latency-queueing-on-cisco-ios/1817)._
