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.

Link Layer Discovery Protocol - Media Endpoint Discovery (LLDP-MED) is an

extension of LLDP intended for managing endpoint devices such as Voice

over IP phones and network switches. The LLDP-MED TLVs advertise

information such as network policy, power, inventory, and device location

details. LLDP and LLDP-MED information can be used by SNMP applications

to simplify troubleshooting, enhance network management, and maintain

an accurate network topology.
