LLDP (Linker Layer Discovery Protocol) is a vendor-neutral Link Layer protocol, which
allows IP phones to receive and/or transmit device-related information from/to directly
connected devices on the network that are also using the protocol, and store the
information about other devices. LLDP transmits information as packets called LLDP
Data Units (LLDPDUs). An LLDPDU consists of a set of Type-Length-Value (TLV) elements,
each of which contains a particular type of information about the device or port
transmitting it.
