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
endpoint products that act as end user communication appliances supporting IP
