www.dell.com | support.dell.com 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. To open the LLDP Properties Page, click Security → LLDP → LLDP Properties in the tree view. Figure 1-1.
