LLDP MED Neighbors
This page provides a status overview of all LLDP-MED neighbors. The displayed
table contains a row for each port on which an LLDP neighbor 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 extentions 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
