ladvd sends LLDP (Link Layer Discovery Protocol) advertisements on all available interfaces. This makes connected hosts visible on managed switches. By default it will run as a privilege-separated daemon. Additional protocols can be enabled. Optionally a list of interfaces which ladvd should utilize can be supplied.

Hardware Donations:

To enable more interoperability testing some small LLDP-capable switches are needed. Please send a mail when you're able to donate test hardware.
