156
Type Description
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.
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 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 and is not supported in later
versions. H3C devices send this type of TLVs only after receiving them.
4. 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 16 .
Table 16 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, the VLAN type, and the 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.
Firmware Revision Allows a terminal device to advertise its firmware version.
Software Revision Allows a terminal device to advertise its software version.
Serial Number Allows a terminal device to advertise its serial number.
Manufacturer Name Allows a terminal device to advertise its vendor name.
Model Name Allows a terminal device to advertise its model name.
Asset ID
Allows a terminal device to advertise its asset ID. The typical case
is that the user specifies the asset ID for the endpoint to facilitate
directory management and asset tracking.
Location Identification
Allows a network device to advertise the appropriate location
identifier information for a terminal device to use in the context of
location-based applications.
