Changing bandwidth of root queue kills traffic (states?)

    1. Get a bunch of torrents running to max out parent WAN queue.
    2. Open WAN traffic graph in browser tab 1.
    3. In browser tab 2, change the bandwidth of parent WAN queue. Save and Apply.

    Watch Wan traffic graph in tab 1. Within a few seconds in and out traffic will drop to 0, then eventually climb back up. You would see the same pattern if you reset firewall states, although I don't know how to confirm whether this is what's actually happening. This did not happen on older snapshots, and throughput would continue unchanged except to adapt to new bandwidth limit as set in the shaper.

    Is this a known behaviour? It seems like a negative change to me.



  • Where is the proof that states have been dropped i do not see?!



  • No, I said "traffic will drop to 0, then eventually climb back up. You would see the same pattern if you reset firewall states". If you have a web page loading at the same momemt it will also freeze.

    I don't assert that the states are dropped, but from a user's point of view that's exactly what it looks like.
