LLDP-MED Network Connectivity Device Definition
LLDP-MED Network Connectivity Devices, as defined in TIA-1057, provide access to 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) :
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 media. Capabilities
include all of the capabilities defined for the previous Generic Endpoint (Class I) and Media
Endpoint (Class II) classes, and are extended to include aspects related to end user devices.
Example product categories expected to adhere to this class include (but are not limited to)
end user communication appliances, such as IP Phones, PC-based softphones, or other
communication appliances that directly support the end user.
