 Basic management TLVs
Organizationally (IEEE 802.1 and IEEE 802.3) specific TLVs

LLDP-MED (media endpoint discovery) TLVs

Basic management TLVs are essential to device management. Organizationally specific TLVs and
LLDP-MED TLVs are used for enhanced device management; they are defined by standardization or other
organizations and thus are optional to LLDPDUs.

Description
Bridge MAC address of the sending device.
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.
Life of the transmitted information on the receiving device.
Marks the end of the TLV sequence in the LLDPDU.
Port description of the sending port.
Assigned name of the sending device.
Description of the sending device.
Identifies the primary functions of the sending device and the
enabled primary functions.
Management address used to reach higher level entities to
assist discovery by network management, and the interface
number and object identifier (OID) associated with the
address.
Description
PVID of the sending port.
Port and protocol VLAN IDs.
A specific VLAN name on the port.
Protocols supported on the port.
