Users Guide

As defined by ANSI/TIA-1057, LLDP-MED provides organizationally specific TLVs (Type Length Value), so that endpoint devices
and network connectivity devices can advertise their characteristics and configuration information. The Organizational Unique
Identifier (OUI) for the Telecommunications Industry Association (TIA) is 00-12-BB.
● LLDP-MED Endpoint Device — any device that is on an IEEE 802 LAN network edge, can communicate using IP, and uses
the LLDP-MED framework.
● LLDP-MED Network Connectivity Device — any device that provides access to an IEEE 802 LAN to an LLDP-MED endpoint
device, and supports IEEE 802.1AB (LLDP) and TIA-1057 (LLDP-MED). The Dell Networking system is an LLDP-MED
network connectivity device.
Regarding connected endpoint devices, LLDP-MED provides network connectivity devices with the ability to:
● manage inventory
● manage Power over Ethernet (POE)
● identify physical location
● identify network policy
