Organizationally specific TLVs and LLDP-MED TLVs are used for enhanced device management.
They are defined by standardization or other organizations and are optional for LLDPDUs.

Basic management TLVs
Table 23 lists the basic management TLV types. Some of them are mandatory to LLDPDUs.

IEEE 802.3 organizationally specific TLVs
Description
Specifies the bridge MAC address of the sending device.
Specifies the ID of the sending port:
•
If the LLDPDU carries LLDP-MED TLVs, the port ID TLV
carries the MAC address of the sending port.
•
If the LLDPDU carries no LLDP-MED TLVs, the port ID TLV
carries the port name.
Specifies the life of the transmitted information on the receiving
device.
Marks the end of the TLV sequence in the LLDPDU.
Specifies the description of the sending port.
Specifies the assigned name of the sending device.
Specifies the description of the sending device.
Identifies the primary functions of the sending device and the
enabled primary functions.
Specifies the following elements:
•
The management address of the local device.
•
The interface number and object identifier (OID) associated
with the address.
Description
Specifies the port VLAN identifier (PVID). An LLDP frame carries only one
TLV of this type.
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.
Specifies the textual name of any VLAN to which the port belongs. An LLDP
frame can carry multiple different TLVs of this type.
Indicates protocols supported on the port. An LLDPDU can carry multiple
different TLVs of this type.
