Protocol Identity
Indicates protocols supported on the port. An LLDPDU can carry
multiple different TLVs of this type.
DCBX Data center bridging exchange protocol.
NOTE:
HP devices support only receiving protocol identity TLVs.

MAC/PHY
Configuration/Status
Contains the rate and duplex capabilities of the sending port, support for
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. HP 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.

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.
