I have discovered interesting behaviour of the clearfogpro switching between lk4.19 and 5.8 and would like to know if others are able to reproduce. And maybe have ideas on how to fix.
- set the lan1-6 interfaces to bridging (example via following /etc/network/interfaces : https://pastebin.com/dpXEBe6g )
- reboot
- plug into your network should be GBit (on lan1-5). Verify you get ip, and can reach other devices.
- run iperf3 between clearfogpro and other gbit device in your network. Should yield about 900MBit/s
Now the interesting part:
- attach another device to the switch
- see how both status leds blink when transfering data via iperf3 ? The bridge seems to run as a hub and not a switch.
- now plug a 100mbit/s device into the bridge.
- test speed to a gbit device with iperf (both directions): one direction will only yield about 100mbit/s.
- while iperf3 is running to the gbit device, unplug and replug the 100mbit/s device on the switch, you should see the rate jump between 100 and 1000.....
NOTICE: This only happens in the direction where the clearfogpro is receiving data. Send speed is still at 1gbit/s.
Now use armbian-config and switch to LK4.19, reproduce steps from above. You should only see one activity led blinking and the switch functioning correctly at 1gbit/s even with a 100mbit/s device connected.
So this leads me to think there's either some difference in the handling of the clearfogpro switch chip (between LK4 and 5) or some difference in bridge package.
It would be great if someone could confirm so I am sure, it is not a problem with my setup.

Hello,
I have discovered interesting behaviour of the clearfogpro switching between lk4.19 and 5.8 and would like to know if others are able to reproduce. And maybe have ideas on how to fix.
Steps to reproduce:
- have a clearfogpro
- get the current armbian image https://archive.armbian.com/clearfogpro/archive/ 20.08
- 'apt update && apt full-upgrade'
- set the lan1-6 interfaces to bridging (example via following /etc/network/interfaces : https://pastebin.com/dpXEBe6g )
- reboot
- plug into your network should be GBit (on lan1-5). Verify you get ip, and can reach other devices.
- run iperf3 between clearfogpro and other gbit device in your network. Should yield about 900MBit/s
Now the interesting part:
- attach another device to the switch
- see how both status leds blink when transfering data via iperf3 ? The bridge seems to run as a hub and not a switch.
- now plug a 100mbit/s device into the bridge.
- test speed to a gbit device with iperf (both directions): one direction will only yield about 100mbit/s.
- while iperf3 is running to the gbit device, unplug and replug the 100mbit/s device on the switch, you should see the rate jump between 100 and 1000.....
