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