LLDP-MED class

An LLDP-MED class specifies an Endpoint type and its capabilities. An Endpoint can belong to one of three LLDP-MED class types:

  • Class 1 (Generic endpoint) - A Class 1 Endpoint requires basic LLDP discovery services, but does not support IP media nor does it act as an end-user communication appliance. A Class 1 Endpoint can be an IP communications controller, other communication-related server, or other device requiring basic LLDP discovery services.
  • Class 2 (Media endpoint) - A Class 2 Endpoint supports media streams and may or may not be associated with a particular end user. Device capabilities include media streaming, as well as all of the capabilities defined for Class 1 Endpoints. A Class 2 Endpoint can be a voice/media gateway, conference, bridge, media server, etc.
  • Class 3 (Communication endpoint) - A Class 3 Endpoint supports end user IP communication. Capabilities include aspects related to end user devices, as well as all of the capabilities defined for Class 1 and Class 2 Endpoints. A Class 3 Endpoint can be an IP telephone, softphone (PC-based phone), or other communication device that directly supports the end user.

Discovery services defined in Class 3 include location identifier (ECS/E911) information and inventory management.

The LLDP-MED device class is advertised when LLDP-MED is enabled on a port.
