Note that LLDP-MED and the LLDP-MED Fast Start mechanism are only intended to run on links between LLDP-
MED Network Connectivity Devices and Endpoint Devices, and as such do not apply to links between LAN
infrastructure elements, including Network Connectivity Devices, or other types of links.
Transmit TLVs: It is possible to select which LLDP-MED information that will be transmitted to the neighbors.
When the checkbox is checked the information is included in the frame transmitted to the neighbor.
Port: The interface name to which the configuration applies.
Transmit TLVs – Capabilities: When checked the switch's capabilities is included in LLDP-MED information
transmitted.
Transmit TLVs – Policies: When checked the configured policies for the interface is included in LLDP-MED
information transmitted.
Transmit TLVs – Location: When checked the configured location information for the switch is included in LLDP-
MED information transmitted.
Transmit TLVs – PoE: When checked the configured PoE (Power Over Ethernet) information for the interface is
included in LLDP-MED information transmitted.
Device Type: Any LLDP-MED Device is operating as a specific type of LLDP-MED Device, which may be either a
Network Connectivity Device or a specific Class of Endpoint Device, as defined below.
A Network Connectivity Device is a LLDP-MED Device that provides 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 that can relay IEEE 802 frames via any
method.
An Endpoint Device an LLDP-MED Device that sits at the network edge and provides some aspect of IP
communications service, based on IEEE 802 LAN technology.
The main difference between a Network Connectivity Device and an Endpoint Device is that only an Endpoint
Device can start the LLDP-MED information exchange.
Even though a switch should always be a Network Connectivity Device, it is possible to configure it to act as an
Endpoint Device, and thereby start the LLDP-MED information exchange (in the case where two Network
Connectivity Devices are connected together).
