TIA-1057 (LLDP-MED) Overview

Link layer discovery protocol — media endpoint discovery (LLDP-MED) as defined by ANSI/ TIA-1057— provides additional organizationally specific TLVs so that endpoint devices and network connectivity devices can advertise their characteristics and configuration information; the 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 EMC 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

LLDP-MED is designed for, but not limited to, VoIP endpoints.
