Traffic not shaping

[felixkinaro]

Hello, we have a deployment setup done and traffic is going through the interfaces. We have gone over the config but traffic is still not shaping, although we are not getting any errors. We have 1 site in the network.json file. DL and UL statistics do not show up under tree. The site has one child site with multiple access points. For the child site and access points we are only getting the RTT latency stats. The attached clients show only the DL limit while UL limit reads NaN

Server setup:

CPU: 16 core Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz NIC 1 and 2: NetXtreme BCM5720 Gigabit Ethernet PCIe

I had an issue on a development branch last night where it looked correct, traffic was flowing through the box, but there was nothing being reported in the gui. Restarting lqosd fixed it. I had been manipulating the network.json file. After a restart everything was stable, even after I continued editing the network file more.

Please try sudo systemctl restart lqosd sudo systemctl stop lqos_scheduler sudo python3 LibreQoS.py It should show if there was an error applying the network.json or ShapedDevices.csv. Once thats resolved you can start lqos_scheduler again.

@rchac I have done this. Running shell sudo python3 LibreQoS.py did not return any error

[rchac]

Have you tried switching interfaceA and interfaceB values in ispconfig.py, then running reload?

@felixkinaro - is this still an issue? If so, please join us in the #libreqos:matrix.org chat.

It appears that the principal ip address was being natted.
