Type Description
Configuration/Status autonegotiation, enabling status of auto negotiation, and the current rate
and duplex mode.
Power Via MDI
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.
Link Aggregation
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).
Maximum Frame Size
Indicates the supported maximum frame size. It is now the MTU of the
port.
Power Stateful Control
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.
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
Table 74 .
Table 74 LLDP-MED TLVs
Type Description
LLDP-MED
Capabilities
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
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.
