LLDP-MED TLVs provide multiple advanced applications for voice over IP (VoIP), such as basic
configuration, network policy configuration, and address and directory management. LLDP-MED
TLVs satisfy the voice device vendors' requirements for cost effectiveness, ease of deployment, and
ease of management. In addition, LLDP-MED TLVs make deploying voice devices in Ethernet easier.
LLDP-MED TLVs are shown in

Description
Contains the rate and duplex capabilities of the sending port, support for auto
negotiation, enabling status of auto negotiation, and the current rate and duplex
mode.
Contains Power supply capability of the port.
Indicates the support of the port for link aggregation, the aggregation capability of
the port, and the aggregation status (that is, whether the link is in an aggregation).
Indicates the supported maximum frame size. It is now the MTU of the port.

Description
Allows a network device to advertise the LLDP-MED TLVs it supports.
Allows a network device or terminal device to advertise VLAN ID of the specific
port, VLAN type, and the Layer 2 and Layer 3 priorities for specific applications.
Allows a network device or terminal device to advertise power supply capability.
This TLV is an extension of the Power Via MDI TLV.
Allows a terminal device to advertise its hardware version.
Allows a terminal device to advertise its firmware version.
Allows a terminal device to advertise its software version.
Allows a terminal device to advertise its serial number.
Allows a terminal device to advertise its vendor name.
Allows a terminal device to advertise its model name.
Allows a terminal device to advertise its asset ID. The typical case is that the user
specifies the asset ID for the endpoint to facilitate directory management and
asset tracking.
Allows a network device to advertise the appropriate location identifier
information for a terminal device to use in the context of location-based
applications.
