iPerf3 issue when generating uplink traffic

[mas-oliveira]

Hello everyone,

I've been making some tests with iPerf3 on the uplink, but I always observe the same behavior. After 20 minutes of sending data, I notice that the iPerf stops transporting data. This means that after 20 minutes, the bitrate and transfer go to zero.

The commands that I've been using are:
On the core => sudo iperf3 -s 1 -p 5202 --forceflush
On the UEs => sudo ip netns exec ue1 iperf3 -c 10.45.0.1 -p 5202 -u -b 1M -i 1 -t 9000

Has anyone faced this issue before? I was trying to see if on 5GC there was something limiting the connection time to 20 min appx but I couldn't find anything.

Thanks a lot,
Marco

It was related to the execution of iPerf on client-side.
