LLDP Overview
The Link Layer Discovery Protocol (LLDP) enables 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.
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 message sets are sent in the
packet’s Type Length Value (TLV) field.
LLDP devices must support chassis and port ID advertisements, as well as
system name, system ID, system description, and system capability
advertisements.
