Is there a queue flow diagram available that shows the packet flow through the queues? i.e., if you have queue trees, simple queues, etc configured, what is the packet flow. The only diagram I have found is the overall packet flow diagram.
There are no such thing as queue flow - there are 4 places where queuing can take place - global-in, global-out, global-total, and interface queue.
Try to place one simple queue and one queue tree queue for the same traffic in the same place and you will be able to find out which is taking traffic first.
There can be a queue flow diagram. You have global-in, global-out, global-total, and interface queue. From a packet’s point of view, ingress is policed and egress is shaped. You can create queue trees, simple queues, etc. A queue flow diagram would show the flow through the different queues as you move from input to output. Why should I have to experiment with simple queues, queues trees, etc. and empirically determine the exact flow? It should be documented.
