LLDPDU TLVs fall into the following categories: basic management TLVs, organizationally (IEEE 802.1
and IEEE 802.3) specific TLVs, and LLDP-MED (media endpoint discovery) TLVs. Basic management TLVs
are essential to device management. Organizationally specific TLVs and LLDP-MED TLVs are used for
improved device management. They are defined by standardization or other organizations and are
optional to LLDPDUs.

Basic management TLVs
Table 68
lists the basic management TLV types in use. Some of them must be included in every
LLDPDU.

The device only supports receiving protocol identity TLVs.
Description
Specifies the bridge MAC address of the sending device.
Specifies the ID of the sending port.
If LLDP-MED TLVs are included in the LLDPDU, 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 no
LLDP-MED TLVs are included, 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 port 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
primary functions that have been enabled.
Specifies the management address used to reach higher level
entities to assist discovery by network management, and the
interface number and OID associated with the address.
Description
Specifies the port's VLAN identifier (PVID). An LLDPDU 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 LLDPDU can carry multiple different TLVs of this type.
Indicates protocols supported on the port. An LLDPDU can carry
multiple different TLVs of this type.
Data center bridging exchange protocol.
