14.4 LLDP-MED
LLDP-MED is an extension of LLDP intended for managing endpoint devices such as Voice over
IP phones and network switches. The LLDP-MED TLVs advertise information such as network
policy, power via MDI, inventory management, and device location details.

Elements
LLDP-MED Device: Refers to any device which implements this Standard.
LLDP-MED Device Type: LLDP-MED devices are comprised of two primary device types:
Network Connectivity Devices and Endpoint Devices.
Network Connectivity Device: Refers to an LLDP-MED Device that provides access to the IEEE
802 based LAN infrastructure for LLDP-MED Endpoint Devices. Bridge is a Network Connectivity
Device.
Endpoint Device: Refers to an LLDP-MED Device at the network edge, providing some aspects
of IP communications service, based on IEEE 802 LAN technology. Endpoint Devices may be a
member of any of the Endpoint Device Classes. Endpoint Devices are composed of three defined
Classes: Class I, Class II and Class III.
Generic Endpoint Device (Class I): The most basic class of Endpoint Device.
Media Endpoint Device (Class II): The class of Endpoint Device that supports media stream
capabilities.
Network Connectivity Devices and Endpoint Devices.

Generic Endpoint Device (Class I): The most basic class of Endpoint Device.
Media Endpoint Device (Class II): The class of Endpoint Device that supports media stream
capabilities.
Communication Device Endpoint (Class III): The class of Endpoint Device that directly supports
end users of the IP communication system.
end users of the IP communication system.
The following LLDP-MED optional TLVs are supported in TL-SG3424P.
Network Policy TLV
The Network Policy TLV allows both Network Connectivity
Devices and Endpoints to advertise VLAN configuration and
associated Layer 2 and Layer 3 attributes that apply for a set of
specific applications on that port.
