The documentation of devices that are connected to a certain switch is usually done by sending and receiving LLDP/CDP packets. Computers, which use Windows as operating system are not able to send LLDP/CDP packets themselves, so the documentation of these computers had to be done manually until now. Because of this manual documentation, there is a risk of having an incorrect and outdated documentation of the network infrastructure. To prevent these problems from happening, this project was created and should result in a service for Windows computers to send LLDP/CDP packets.

The project contains a Windows service, which is distributed via a central server onto all clients. If the service is enabled, it sends LLDP/CDP packets from the computers to the network device, where it is plugged in.  It should also use as few authorizations as possible and its operation should always be in the background. To use the program, all you have to do is install it on all clients that should identify themselves to the network device. To configure the service, a group policy template for Windows servers was created. If the parameters are changed on the server, it automatically updates the services on all clients. The code is open source to maximize the reliability of our program.
