LDWin is an application to assist in identifying switch port information. And, it can be used by almost anyone. Can’t access a network closet to identify the switch port information? Just use LDWin. Have a technician in the field that isn’t network savvy? Use LDWin!
Because LLDP and CDP are Layer 2 protocols, the connected device doesn’t require full network access for the application to gather the appropriate information.
I’ve included a link below to Github where the application can be downloaded. The page includes sample images and instruction on how to use the application.
