Stealthy operation on LAN

I noticed that on LAN, the router emits several protocols.

For example:
  1. The Neighbors discovery (port 5678).
    It can be disabled from: IP->Neighbors->Discovery.
    (Link to similar thread.)
  2. The 802.2 protocol which has MAC destination address 01:80:C2:00:00:00.
    How do I disable it?
I want that for LAN, the router will be as silent as possible.

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.

I just unplug my pC when not in use. Super stealthy.

Thanks, it was initially set to RSTP.


About these functions:
  • auto time zone
  • cloud time sync
  • internet detect
They are transmitted from the WAN port, right?
(Assuming that the WAN port is the "default" route in the Routing Table.)
In that case, it is fine.
