- The Neighbors discovery (port 5678).
It can be disabled from: IP->Neighbors->Discovery.
(Link to similar thread.)
- The 802.2 protocol which has MAC destination address 01:80:C2:00:00:00.
How do I disable it?
Thanks, it was initially set to RSTP.On bridge, set STP protocol to none.
Also disable auto time zone and cloud time sync and internet detect, as these are other sources of unwanted traffic.
