3.2.11.2. LLDP - LLDP-MED Neighbours
This page provides a status overview of all LLDP-MED neighbours. The displayed table
contains a row for each port on which an LLDP neighbour is detected. This function applies to
VoIP devices which support LLDP-MED. The columns hold the following information:
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).
