Type
TLV
Description
127
Protocol Identity
Indicates the protocols that the 
port can process. The 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. The 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.
