Configuring LLDP
The
Link Layer Discovery Protocol
(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
system, 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.
The
LLDP Properties
page contains fields for configuring LLDP.
