Type Description
Protocol Identity
Indicates protocols supported on the port. An LLDPDU can carry multiple
different TLVs of this type.
NOTE:
H3C devices support only receiving protocol identity TLVs.
3. IEEE 802.3 organizationally specific TLVs
Table 24 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 capability of the port, including the PoE
type (PSE or PD), PoE mode, whether PSE power supply is supported,
whether PSE power supply is enabled, and whether the PoE mode is
controllable.
Link Aggregation
Indicates the aggregation capability of the port (whether the link is
capable of being aggregated), and the aggregation status (whether
the link is in an aggregation).
Maximum Frame Size
Indicates the supported maximum frame size. It is now the maximum
transmission unit (MTU) of the port.
Power Stateful Control
Indicates the power state control configured on the sending port,
including the power type of the PSE/PD, PoE sourcing/receiving
priority, and PoE sourcing/receiving power.
NOTE:
The Power Stateful Control TLV is defined in IEEE P802.3at D1.0. Later versions no longer support this
TLV. H3C devices send this type of TLV only after receiving them.
LLDP-MED TLVs
LLDP-MED TLVs provide multiple advanced applications for 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 Table 25 .
Table 25 LLDP-MED TLVs
Type Description
LLDP-MED Capabilities
Allows a network device to advertise the LLDP-MED TLVs that it
supports.
Network Policy
Allows a network device or terminal device to advertise the VLAN ID of
the specific port, VLAN type, and Layer 2 and Layer 3 priorities for
specific applications.
Extended Power-via-MDI
Allows a network device or terminal device to advertise power supply
capability. This TLV is an extension of the Power Via MDI TLV.
Hardware Revision Allows a terminal device to advertise its hardware version.
