Specific
Optional TLVs are grouped into two categories including basic management TLV and
Organizationally-specific TLV.
1) Basic Management TLV
A set of TLVs considered to be basic to the management of the network stations are required
for all LLDP implementations.
2) Organizationally Specific TLV
Description
Mark the end of the TLV sequence in LLDPDUs.
Any information following an End Of LLDPDU
TLV shall be ignored.
Identifies the Chassis
connected device.
Identifies the specific port that transmitted the
LLDP frame. When the device does not
advertise MED TLV, this field displays the port
name of the port; when the device advertises
MED TLV, this field displays the MAC address
of the port.
Indicates the number of seconds that the
neighbor device is to regard the local
information to be valid.
Identifies the description string of the port.
Identifies the system name.
Identifies the system description.
Identifies the main functions of the system and
the functions enabled.
Identifies the management IP address, the
corresponding interface number and OID
(Object Identifier). The management IP address
is specified by the user.
Allows different organizations, such as IEEE
802.1, IEEE 802.3, IETF, as well as individual
software and equipment vendors, to define
TLVs that advertise information to remote
device.
