‐ Simplifies the use of and enhances the ability of network management tools in multi-vendor
environments
‐ Enables discovery of accurate physical network topologies such as which devices are
neighbors and through which ports they connect
‐ Enables discovery of stations in multi-vendor environments
• Network Inventory Data:
‐ Supports optional system name, system description, system capabilities and management
address
‐ System description can contain the device product name or model number, version of
hardware type, and operating system
‐ Provides device capability, such as switch, router, or WLAN access point
• Network troubleshooting:
‐ Information generated by LLDP can be used to detect speed and duplex mismatches
‐ Accurate topologies simplify troubleshooting within enterprise networks
‐ Can discover devices with misconfigured or unreachable IP addresses
LLDP-MED overview
LLDP-MED is an extension to LLDP. This protocol enables advanced LLDP features in a Voice over IP
(VoIP) network. Whereas LLDP enables network discovery between Network Connectivity devices,
LLDP-MED enables network discovery between Network Connectivity devices and media Endpoints
such as, IP telephones, softphones, VoIP gateways and conference bridges.
The following diagram illustrates LLDP-MED connectivity.
