Type TLV Description

127 Protocol Identity Indicates the protocols that the

port can process. Dell

Networking OS does not

currently support this TLV.

IEEE 802.3 Organizationally

Specific TLVs

127 MAC/PHY Configuration/Status 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.

127 Power via MDI 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.

127 Link Aggregation 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.

127 Maximum Frame Size Indicates the maximum frame

size capability of the MAC and

PHY.

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.
