3.7.2 LLDP-MED Neighbors
Status 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 the using service
communication IP in participate and edge, network LAN 802 IEEE at located are
TIA-1057, defined as Devices, Endpoint>
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. Fore-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
