Devices. An LLDP-MED Network Connectivity Device is a LAN access device
based on any of the following technologies:
1. LAN Switch/Router
2. IEEE 802.1 Bridge
3. IEEE 802.3 Repeater (included for historical reasons)
4. IEEE 802.11 Wireless Access Point
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.
