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 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
• identify physical location
• identify network policy
LLDP-MED is designed for, but not limited to, VoIP endpoints.

TIA Organizationally Specific TLVs

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

TLV
Link Aggregation
Maximum Frame Size
SubType
1
Description
LLDP, but is available and mandatory (non-
configurable) in the LLDP-MED
implementation.
Indicates whether the link is capable of
being aggregated, whether it is currently in a
LAG, and the port identification of the LAG.
Dell Networking OS does not currently
support this TLV.
Indicates the maximum frame size capability
of the MAC and PHY.

device supports LLDP-MED
• what LLDP-MED TLVs it
supports
