The Link attribute/column shows which Network device a Device is connected to.
So, Link=Route10 may or may not be the right thing to show for other brands of switches and APs. Either it shows wrong because it believes it is directly attached to the Route10, or it shows correct (by design) because it is the nearest upstream Alta network device?!
The wired devices in @richardvaughan’s case showed Port=Lx and several devices on the same ports. I assumed the letter L in the Port meant a port on the Route10 while ports on Alta switches was number only. That’s how it works for all my devices attached to Alta Network devices. I don’t have any other branded managed switch in the network currently to check what that would look like.
My bet was that your devices’ Ports were actually wrong as well when the VLANs were wrong, while the Ports were correct (blank) when the VLANs were correct. At least, that was my thought according to
