I'm trying to do a "map" of my company's network to see all of its devices (switch, router... ). After some research, Zenmap (GUI of Nmap) semmed to be a good tool. But when I scanned the network on a specific IP adresse range, all of the devices found weren't connected to switchs that I discovered (and they should be !). For example, the switch 192.168.50.61 should be connected with the switch 192.168.50.62 (I saw the physical link between them).
Are there any plugins or Nmap commands to solve this issue ?
