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.
