5. Any device that supports the IEEE 802.1AB and MED extensions defined by
TIA-1057 and can relay IEEE 802 frames via any method.
LLDP-MED Endpoint Device Definition :
LLDP-MED Endpoint Devices, as defined in TIA-1057, are located at the IEEE
802 LAN network edge, and participate in IP communication service using the
LLDP-MED framework.
Within the LLDP-MED Endpoint Device category, the LLDP-MED scheme is
broken into further Endpoint Device Classes, as defined in the following.
Each LLDP-MED Endpoint Device Class is defined to build upon the capabilities
defined for the previous Endpoint Device Class. For-example will any LLDP-
MED Endpoint Device claiming compliance as a Media Endpoint (Class II) also
support all aspects of TIA-1057 applicable to Generic Endpoints (Class I), and
any LLDP-MED Endpoint Device claiming compliance as a Communication
Device (Class III) will also support all aspects of TIA-1057 applicable to both
Media Endpoints (Class II) and Generic Endpoints (Class I).
LLDP-MED Generic Endpoint (Class I) :
The LLDP-MED Generic Endpoint (Class I) definition is applicable to all endpoint
products that require the base LLDP discovery services defined in TIA-1057,
however do not support IP media or act as an end-user communication
appliance. Such devices may include (but are not limited to) IP Communication
Controllers, other communication related servers, or any device requiring basic
services as defined in TIA-1057.
Discovery services defined in this class include LAN configuration, device
location, network policy, power management, and inventory management.
LLDP-MED Media Endpoint (Class II) :
The LLDP-MED Media Endpoint (Class II) definition is applicable to all endpoint
products that have IP media capabilities however may or may not be
associated with a particular end user. Capabilities include all of the capabilities
defined for the previous Generic Endpoint Class (Class I), and are extended to
include aspects related to media streaming. Example product categories
expected to adhere to this class include (but are not limited to) Voice / Media
Gateways, Conference Bridges, Media Servers, and similar.
Discovery services defined in this class include media-type-specific network
layer policy discovery.
LLDP-MED Communication Endpoint (Class III) :
The LLDP-MED Communication Endpoint (Class III) definition is applicable to all
