Flow rules and IP filtering

Q/A

I’d like to control Flow Rules by Webconsole, are there any examples for that?

I’ve tried following

I was expecting that bandwidth will be limited to 5 Mbps.
But there is no effect on it from UE perspective, tested with iperf3 (tcp).
I have also tried following rules

permit in 6 from any to any
permit out 6 from any to any

permit in 6 from any to 10.100.201.11
permit out 6 from 10.100.201.11 to any

permit out 6 from any to any

Am i using invalid syntax or this is not implemented?

Hi @konradkar2

I think your configuration is well.
But the free5GC is not support QoS enforcement currently.

If you just want to verify your rules, you can use the commands below:

sudo echo #gtpiface #id > /proc/gtp5g/pdr
sudo cat /proc/gtp5g/pdr
sudo echo #gtpiface #id > /proc/gtp5g/far
sudo cat /proc/gtp5g/far
sudo echo #gtpiface #id > /proc/gtp5g/qer
sudo cat /proc/gtp5g/qer

Thanks.

Thank you
So none of the rules on the screen will actually impact the session?

I’m kinda lost with the kernel module,
what exactly you mean by #gtpiface and #id?

I’m guessing gtpiface is linux interface name.
And for ID, is it session id?
