4.14.1 Link Layer Discovery Protocol

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.
