Link flapping on TL-SG3428 v2.0 with client device
i've the problem on a omada-controller-managed tl-sg3428 v2 with latest firmware and a normal sff computer.
On this computer theres a windows 10 pro, latest patches and hyper-v role.
client has 2 dedicated nics (Realtek), one for external network/vlan, other is internal.
on that client im using a vm with sophos xg and several vlans.
the external nic on switchport 15 is always flapping. Even if i configure 1000/fdx (no auto) fixed i got these errors, but only with the external nic.
I dont have changed the switch-port so i cannot tell you, if the error go away after that. I've also disabled spanning tree or loopback protection.
But how can i see detailed logs on omada? Im just seeing that there is a connect/disconnect, but no errors on that port. :-/
Or am i misinterpreting these messages and the meaning is only for this named vlan and not the port/link itself?
If so, how can i configure it correctly to avoid this flapping behavior?
Thanks in advance,
