I have noticed that the neighbor map often includes devices that are not actually neighbors (unless my idea of what constitutes a neighbor is incorrect).
My expectation is that the neighbor map would include only devices physically connected to the device.
For example, I have one server that shows several neighbors in the map, even though it has one interface connected to a switch - and that switch is not even shown in the map!
Meanwhile, the neighbor list is totally empty.
I have both xdp and mac enabled for mapping.
There are a number of relationships showing up in the network map that don’t actually exist. I’m wondering what I need to do to troubleshoot this stuff.
Here’s the output of my validate.php:
