End of LLDPDU Marks the end of the TLV sequence in the LLDPDU.
Port Description Specifies the port description of the sending port.
Optional.
System Name Specifies the assigned name of the sending device.
System Description Specifies the description of the sending device.
System Capabilities
Identifies the primary functions of the sending device and the
enabled primary functions.

Port VLAN ID
Specifies the port's VLAN identifier (PVID). An LLDPDU carries only one TLV of
this type.
Port And Protocol VLAN ID
Indicates whether the device supports protocol VLANs and, if so, what VLAN
IDs these protocols will be associated with. An LLDPDU can carry multiple
different TLVs of this type.
VLAN Name
Specifies the textual name of any VLAN to which the port belongs. An LLDPDU
can carry multiple different TLVs of this type.
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.
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 autonegotiation, enabling status of autonegotiation, and
the current rate and duplex mode.
Power Via MDI
Contains the power supply capability of the port, including the 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 is
capable of being 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.
