Hello,

I'm sorry, but PRTG cannot discover what is connected to a switch/router and then automatically draw a network map. We find that most all automatic-generated network maps differ so much from the "real network" or what one thinks of the structure of a network that one spends a lot of time re-arranging such an "auto-map".
But map ins PRTG, which have to be made manually, can of course show you the state of a connection between devices. You can either do that by placing stats-icon map-objects of certain sensors near a connection-line between devices on a map, or use the connection-line itself, which will change its color slightly, according to the 'worst' sensor-state on the attached device.

best regards.
