NOTE:
The Power Stateful Control TLV is defined in IEEE P802.3at D1.0. The later versions no longer support this
TLV. 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 25 LLDP-MED TLVs
Type Description
LLDP-MED Capabilities
Allows a network device to advertise the LLDP-MED TLVs it supports.
Network Policy
Allows a network device or terminal device to advertise VLAN ID of the
specific port, 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.
Management address
The management address of a device is used by the network management system to identify and
manage the device for topology maintenance and network management. The management address is
encapsulated in the management address TLV.
How LLDP works
Operating Modes of LLDP
LLDP can operate in one of the following modes:
•
TxRx mode. A port in this mode sends and receives LLDPDUs.
•
Tx mode. A port in this mode only sends LLDPDUs.
•
Rx mode. A port in this mode only receives LLDPDUs.
