Type
QCN
NOTE:
The device can receive protocol identity TLVs and VID usage digest TLVs, but it cannot send
these TLVs.

MAC/PHY Configuration/Status
Power Via MDI
Maximum Frame Size
Power Stateful Control
Energy-Efficient Ethernet
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

LLDP-MED Capabilities
Description
Quantized Congestion Notification.
NOTE:
Switches of this series do not support QCN TLVs.
