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

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. Fore-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
