As dened by ANSI/TIA-1057, LLDP-MED provides organizationally specic TLVs (Type Length Value), so that endpoint devices and
network connectivity devices can advertise their characteristics and conguration information. The Organizational Unique Identier
(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
