In the camera table view, in the LLDP column, does it matter what device I see? In some cases I see a switch, in others a nearby IP phone, and in others another Meraki camera. I'm not familiar with LLDP; any insight is appreciated.
LLDP basically gives you information about other devices on the same lan segment. It's not always enabled or supported on network equipment. You may also see LLDP information about devices that don't connect directly to whatever you're looking at.
So if you don't see LLDP info? It may just mean that whatever your camera is connected to, LLDP is disabled or not supported.
If you see multiple devices? Then your device is getting LLDP responses from a number of devices, possibly due to a misconfiguration somewhere along the way between your camera and the random other device.
