Power Stateful Control
The power stateful control TLV is defined in IEEE P802.3at D1.0. The later versions no longer
support this TLV. HPE devices send this type of TLVs only after receiving them.

LLDP-MED TLVs
LLDP-MED TLVs provide multiple advanced applications for 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

Description
autonegotiation, enabling status of auto negotiation, and the current rate
and duplex mode.
Contains the power supply capability of the port:
•
Port class (PSE or PD).
•
Power supply mode.
•
Whether PSE power supply is supported.
•
Whether PSE power supply is enabled.
•
Whether pair selection can be 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 MTU of the
port.
Indicates the power state control configured on the sending port, including
the following:
•
Power supply mode of the PSE/PD.
•
PSE/PD priority.
•
PSE/PD power.

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.
Allows a terminal device to advertise its software version.
Allows a terminal device to advertise its serial number.
Allows a terminal device to advertise its vendor name.
Allows a terminal device to advertise its model name.
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.
Allows a network device to advertise the appropriate location identifier
information for a terminal device to use in the context of location-based
applications.
