4.15 LLDP
Link Layer Discovery Protocol (LLDP) is used to discover basic information about neighboring devices on the local
broadcast domain. LLDP is a Layer 2 protocol that uses periodic broadcasts to advertise information about the sending
device. Advertised information is represented in Type Length Value (TLV) format according to the IEEE 802.1ab standard,
and can include details such as device identification, capabilities and configuration settings. LLDP also defines how to store
and maintain information gathered about the neighboring network nodes it discovers.
