Page 206 highlights

Type Protocol Identity Description Indicates protocols supported on the port. An LLDPDU can carry multiple different TLVs of this type. NOTE: HP devices support only receiving protocol identity TLVs. 3. IEEE 802.3 organizationally specific TLVs Table 25 IEEE 802.3 organizationally specific TLVs Type MAC/PHY Configuration/Status Power Via MDI Link Aggregation Maximum Frame Size Power Stateful Control Description Contains the bit-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, which can be 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 aggregation capability of the port (whether the link is capable of being aggregated), and the aggregation status (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 or PD, PoE sourcing and receiving priority, and PoE sourcing and receiving power. 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. 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 26. Table 26 LLDP-MED TLVs Type LLDP-MED Capabilities Network Policy Extended Power-via-MDI 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. 197

Type
Description
MAC/PHY
Configuration/Status
Contains the bit-rate and duplex capabilities of the sending port, support for
auto negotiation, enabling status of auto negotiation, and the current rate
and duplex mode.
Power Via MDI
Contains the power supply capability of the port, including the Power over
Ethernet (PoE) type, which can be 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.
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 or PD, PoE sourcing and receiving priority, and
PoE sourcing and receiving power.
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.
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

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
