the IEEE 802 based LAN infrastructure for LLDP-MED Endpoint 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) :
