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 21 IEEE 802.3 organizationally specific TLVs
Type Description
MAC/PHY Configuration/Status
Contains the bit-rate and duplex capabilities of the 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.
•
Power supply type.
•
Power
source.
•
Power
priority.
•
PD
requested
power.
•
PSE
allocated
power.
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.
Energy-Efficient Ethernet
Indicates Energy Efficient Ethernet (EEE).
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
.
Table 22 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 a port, the VLAN type, and the Layer 2 and Layer 3
priorities for specific applications.
