MED device class:

Connectivity device—An intermediate device that provide network

 

connectivity.

 

Class I—A generic endpoint device. All endpoints that require the

 

discovery service of LLDP belong to this category.

Device class

Class II—A media endpoint device. The class II endpoint devices

support the media stream capabilities and the capabilities of generic

 

 

endpoint devices.

 

Class III—A communication endpoint device. The class III endpoint

 

devices directly support end users of the IP communication system.

 

Providing all capabilities of generic and media endpoint devices,

 

Class III endpoint devices are used directly by end users.
