NOTE:
• H3C devices support only receiving protocol identity TLVs and VID usage digest TLVs.
• Layer 3 Ethernet ports support only link aggregation TLVs.

NOTE:
The Power Stateful Control TLV is defined in IEEE P802.3at D1.0 and is not supported in later
versions. H3C devices send this type of TLVs only after receiving them.

LLDP-MED TLVs
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 provide a cost-effective and easy-to-use solution for deploying voice devices
in Ethernet. LLDP-MED TLVs are shown in

Description
Contains the bit-rate and duplex capabilities of the port, support
for autonegotiation, enabling status of autonegotiation, and the
current rate and duplex mode.
Contains the power supply capabilities of the port:
•
Port class (PSE or PD).
•
Power supply mode.
•
Whether PSE power supply is supported.
•
Whether PSE power supply is enabled.
•
Whether pair selection can be controlled.
•
Power supply type.
•
Power source.
•
Power priority.
•
PD requested power.
•
PSE allocated power.
Indicates the supported maximum frame size. It is now the MTU
of the port.
Indicates the power state control configured on the sending
port, including the following:
•
Power supply mode of the PSE/PD.
•
PSE/PD priority.
•
PSE/PD power.
Indicates Energy Efficient Ethernet (EEE).

Description
Allows a network device to advertise the LLDP-MED TLVs that it
supports.
Allows a network device or terminal device to advertise the
VLAN ID of a port, the VLAN type, and the Layer 2 and Layer 3
priorities for specific applications.
