13.4 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.
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.
Communication Device Endpoint (Class III): The class of Endpoint Device that directly supports

TLV
Description
Network Policy TLV
The Network Policy TLV allows both Network Connectivity
Devices and Endpoints to advertise VLAN configuration and
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.
of specific applications on that port.
