What I can tell you is Loop Protection was fixed in v1.5.0rc1 for SFP ports, it was broken and not working.
Not everyone can use Loop Protection with their network configuration and the equipment they use especially large flat networks.
I would suggest you use STP instead of Loop Protection.
If your positive this is a FALSE Loop detection then DIsable Loop Protection. If it is a False Loop Protection report then nothing bad will happen.
So today I had to disable RSTP at all. About 24 hours later (without any RSTP issue) one Netonix switch (WS-10-250-AC) started to repeat RSTP messages discarding / learning / forwarding on one port. All clients behind this port in switch started to complain about repeated 15s timeouts. Then I have found this thread
https://forum.netonix.com/viewtopic.php?f=6&t=2018&start=30 . There is not a result how it was solved. But maybe I have some important information to this topic...
1/ Device in this problematic port is Ubiquiti PowerBeam M5 as one of our P2P link to other location - other end PowerBeam M5 again is connected to Ubiquiti Edgeswitch 8XP (previously called ToughSwitch)
2/ There are another two P2P links to other locations in the same Netonix switch (other end is connected directly to client's router, no Netonix or other RSTP switch)
3/ And one P2P link as "uplink" and identified as "root" in RSTP tab - other end is connected to another Netonix WS-10-250-AC.
4/ The state of discarding / learning / forwarding started EXACTLY at the time when I changed configuration of that P2P link connected to that port (I switch role of P2P link from STA-AP to AP-STA).
I think that the problem would not be the fact, that I had changed the config of that link, but the fact that during this change the unit reboot itself and generated port down / up state. Since this time loop of RSTP discarding / learning / forwarding started. I had no chance to test more (reboot that PowerBeam again, reboot other unit connected to the switch, reboot the switch itself...), I had just quickly disabled RSTP which solved the problem at all. It could be also related with the fact that on other side is EdgeSwitch 8XP (ToughSwitch). I was on fw 1.4.8 in Netonix and 1.4.1 in EdgeSwitch 8XP.
Any advice / explanation?
