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

IEEE 802.3 organizationally specific TLVs
Table 19
IEEE 802.3 organizationally specific TLVs
Type Description
MAC/PHY Configuration/Status
Contains the bit-rate and duplex capabilities of the sending port,
support for autonegotiation, enabling status of autonegotiation,
and the current rate and duplex mode.
Power Via MDI
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.
Maximum Frame Size
Indicates the supported maximum frame size. It is now the MTU of
the port.
Power Stateful Control
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.
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 Capabilities
Allows a network device to advertise the LLDP-MED TLVs that it
supports.
