Hi,

I would like to do this task : detect any unplugged cables/devices across the network. For examples : at time t, detect every connected device across the network. At time t+x, detect every connected device across the network and do the difference with the previous result. It should give me the devices that got unplugged.

The reason being, I have to deal with an existing network with 0 documentation and would like to map ethernet cables to the ethernet wall plugs' physical locations.

Thanks

Hi

if switch are Cisco, you can use Cisco network assistant for manage and showing topology of your new network.
