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.
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
satisfy 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
Table 76 LLDP-MED TLVs

LLDP-MED Capabilities
Network Policy
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, 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 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 76.
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.
Description
Specifies the textual name of any VLAN to which the port belongs.
An LLDPDU can carry multiple different TLVs of this type.
Indicates protocols supported on the port. An LLDPDU can carry
multiple different TLVs of this type.
Data center bridging exchange protocol.
