Section 13. Configuring LLDP
Link Layer Discovery Protocol
(LLDP) is a Layer 2 protocol that allows a network device supporting the 802.1ab
standard to advertise its identity and capabilities on a local network. LLDP allows network managers to
troubleshoot and enhance network management by discovering and maintaining network topologies over
multi-vendor environments. LLDP discovers network neighbors by standardizing methods for network devices to
advertise themselves to other systems, and to store discovered information. Device discovery information
includes:
•
Device Identification
•
Device Capabilities
•
Device Configuration
The advertising device transmits multiple advertisement message sets in a single LAN packet. The multiple
advertisement sets are sent in the packet Type Length Value (TLV) field. LLDP devices must support chassis and
port ID advertisement, as well as system name, system ID, system description, and system capability
advertisements.
