NOTE:
HP devices only support receiving protocol identity TLVs.
•
Layer 3 Ethernet interfaces do not support IEEE 802.1 organizationally specific TLVs.
•
3. IEEE 802.3 organizationally specific TLVs
Table 74 IEEE 802.3 organizationally specific TLVs
Type
MAC/PHY
Configuration/Status
Power Via MDI
Link Aggregation
Maximum Frame Size
Power Stateful Control
NOTE:
The Power Stateful Control TLV is defined in IEEE P802.3at D1.0. The later versions no longer support
this TLV. HP 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 meet the voice device vendors' requirements for cost effectiveness, ease of deployment, and
ease of management. In addition, LLDP-MED TLVs make deploying voice devices in Ethernet easier.
LLDP-MED TLVs are shown in

Description
Contains the rate and duplex capabilities of the sending port, support for
auto negotiation, enabling status of auto negotiation, and the current rate
and duplex mode.
Contains the power supply capability of the port, including the Power over
Ethernet (PoE) type (Power Sourcing Equipment (PSE) or Powered Device
(PD)), PoE mode, whether PSE power supply is supported, whether PSE
power supply is enabled, and whether the PoE mode is controllable.
Indicates the support of the port for link aggregation, the aggregation
capability of the port, and the aggregation status (or whether the link is in an
aggregation).
Indicates the supported maximum frame size. It is now the Maximum
Transmission Unit (MTU) of the port.
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.
Table 75.
Description
Allows a network device to advertise the LLDP-MED TLVs that it supports.
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.
Allows a network device or terminal device to advertise power supply
capability. This TLV is an extension of the Power Via MDI TLV.
Allows a terminal device to advertise its hardware version.
Allows a terminal device to advertise its firmware version.
