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
