NOTE:
• HP devices support only receiving protocol identity TLVs.
• Layer 3 Ethernet ports do not support IEEE 802.1 organizationally specific TLVs.

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 PoE type (PSE or 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
can be 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 MTU of
the port.
Power Stateful Control
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.
NOTE:
The power stateful control TLV is defined in IEEE P802.3at D1.0. Later versions no lon
g
er support this
TLV. HP devices send this type of TLV only after receiving them.
4. 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 23.

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, VLAN type, and 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.
