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.
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 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.
