Hi,
I've been using OmadaSDN for a year.
Used to have a WRT54, then three WRT54 with Tomato in "mesh" operation, so to speak, Then an Asus router with three access points, then a Fritzbox, four access points with several managed netgear switches, but I've never had anything as unreliable and unstable as my current OmadaSDN, and the whole thing then scolds itself as a business solution.
Several loop detections and port blockings are detected several times a week, then everything is not available again for a short time because it is newly integrated into OmadaSDN, sometimes hours later, sometimes days later everything starts all over again.
e.g. added a SG2008P to OmadaSDN yesterday.
No device is connected to the switch, only the uplink cable to Port1, two hours later I had a loop detection message on Port8 for the first time...
That can not be?
I switched off Mesh so that a loop doesn't occur somewhere via an EAP.
Have testet RSTP on and off, used Loopback detection or Spanning Tree,... no difference
Is there no technical possibility in Omada SDN to determine why this loop occurs?
It's a business system?????
What can i do, those loops are annoying 
Here is a simple sketch of my OmadaSDN
I primarily get the loop detection on SG2218 port 15 and T1600G port 24, but also always on other ports.
What i forgot, the OC200 is still connected to the R605 port4.
Maybe someone has a tip for me?
THANKS

Everything just annoying
@Tescophil
I have read the linked post.
This is pretty similar to my problem.
I also use a Sonos speaker, this is connected to the SG3428 via a LAN cable on Port3.
I don't understand, why do I then get a loop on the T1500G-PS?
What's the logic behind that?
@Somnus
The Lan cables are all okay.
The connections between the switches were all replaced with CAT7 cables last summer.
Has also done a specialist workshop and checked with appropriate equipment, was not a hobby project by myself 
So I don't think there is a problem with the LAN-Cables.
I don't want to radically turn off loop detection.
That doesn't solve the problem.
There must be some reason why OmadaSDN detects a loop.
I would have liked to have clarified that.
As mentioned above, we are talking about a business system here, I don't think it's the solution, just turn off the error message
@Hoamboy
I have already connected the OC200 to the SG3428 and the SG2218. There was no difference, always loops
@Tescophil
Had a similar idea this morning, and so I disabled all EAP.
without EAP, no Wifi, no Wifi no loopwith Sonos, or?
This is the result
I'll test it and unplug the Sonos.
But it is difficult to check, sometimes everything works for two or three days and then there are days like today where I had 8 loop detections so far...
Which I still don't understand why do the loops appear on the T1500G-10PS?
Nothing is plugged in except for the uplink cable?
