Figure 5-47. LLDP-MED Neighbours information screen.
NOTE: If your network without any device supports LLDPMED, then the table will show ”No LLDP-MED neighbor information
found.”
Parameter description:
• Port: The port on which the LLDP frame was received.
• Device Type: LLDP-MED Devices are comprised of two primary Device Types: Network Connectivity Devices and Endpoint
Devices.
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, but 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.
