CHAPTER 2: SYSTEM
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.
Discovery services defined in this class include provision of location identifier (including ECS / E911 information), embedded L2 switch
support, inventory management.
LLDP-MED Capabilities: LLDP-MED Capabilities describes the neighborhood unit’s LLDP-MED capabilities. The possible capabilities
are:
1. LLDP-MED capabilities
2. Network Policy
3. Location Identification
4. Extended Power via MDI - PSE
5. Extended Power via MDI - PD
6. Inventory
7. Reserved
