18 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.
This section describes the commands used to configure LLDP.
