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.
