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.

TLV
Protocol Identity
MAC/PHY Configuration/Status
Power via MDI
Link Aggregation
Maximum Frame Size
Description
Indicates the protocols that the
port can process. Dell
Networking OS does not
currently support this TLV.
Indicates the capability and
current setting of the duplex
status and bit rate, and whether
the current settings are the result
of auto-negotiation. This TLV is
not available in the Dell
Networking OS implementation
of LLDP, but is available and
mandatory (non-configurable) in
the LLDP-MED implementation.
Dell Networking supports the
LLDP-MED protocol, which
recommends that Power via MDI
TLV be not implemented, and
therefore Dell Networking
implements Extended Power via
MDI TLV only.
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.
