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 Force10 system is an LLDP-MED network connectivity device.
With regard to 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.

TIA Organizationally Specific TLVs

The Dell Force10 system is an LLDP-MED Network Connectivity Device (Device Type 4). Network
connectivity devices are responsible for:
• transmitting an LLDP-MED capabilities TLV to endpoint devices
• storing the information that endpoint devices advertise
Table 30-3 describes the five types of TIA-1057 Organizationally Specific TLVs.
