Type Description Remarks
Port ID
ID of the sending port
If the LLDPDU carries LLDP-MED TLVs, the port ID TLV carries
the MAC address of the sending port or the bridge MAC in case
the port does not have a MAC address. If the LLDPDU carries no
LLDP-MED TLVs, the port ID TLV carries the port name.
Time To Live Life of the transmitted information on the receiving device
End of LLDPDU Marks the end of the TLV sequence in the LLDPDU
Port Description Port description of the sending port
System Name Assigned name of the sending device
System Description Description of the sending device
System Capabilities
Identifies the primary functions of the sending device and the
enabled primary functions
Management Address
Management address, and the interface number and OID (object
identifier) associated with the address
Optional
2) IEEE 802.1 organizationally specific TLVs

Type Description
Port VLAN ID
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
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.
Currently, H3C devices only support receiving protocol identity TLVs.
