5.22 LLDP Commands
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.
