4.12 LLDP

4.12.1 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.
