• 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, and they are defined by standardization or
other organizations and are optional to LLDPDUs.
1. Basic management TLVs:
Table 20 list
s the basic management TLV types. Some of them are mandatory to LLDPDUs, that is,
must be included in every LLDPDU.

Remarks
Chassis ID Specifies the bridge MAC address of the sending device.
Mandatory.
Port ID
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 or the bridge MAC if 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
Specifies the life of the transmitted information on the
receiving device.
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.
Management Address
Specifies the management address, and the interface number
and OID associated with the address.

Port VLAN ID Specifies the 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 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.
