Page 214 highlights

The following table shows the details about the currently defined TLVs. TLV type TLV Name Description Usage in LLDPDU 0 End of LLDPDU Mark the end of the TLV sequence in LLDPDUs. Mandatory Any information following an End Of LLDPDU TLV shall be ignored. 1 Chassis ID Identifies the Chassis address of the Mandatory connected device. 2 Port ID Identifies the specific port that transmitted the Mandatory 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. 3 Time To Live Indicates the number of seconds that the Mandatory neighbor device is to regard the local information to be valid. 4 Port Description Identifies the description string of the port. Optional 5 System Name Identifies the system name. Optional 6 System Identifies the system description. Description Optional 7 System Identifies the main functions of the system and Optional Capabilities the functions enabled. 8 Management Identifies the management IP address, the Optional Address corresponding interface number and OID (Object Identifier). The management IP address is specified by the user. 127 Organizationally Allows different organizations, such as IEEE Optional Specific 802.1, IEEE 802.3, IETF, as well as individual software and equipment vendors, to define TLVs that advertise information to remote device. 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 204

The following table shows the details about the currently defined TLVs.
TLV type
TLV Name
Description
Usage in
LLDPDU
0
End of LLDPDU
Mark the end of the TLV sequence in LLDPDUs.
Any information following an End Of LLDPDU
TLV shall be ignored.
Mandatory
1
Chassis ID
Identifies
the
Chassis
address
of
the
connected device.
Mandatory
2
Port ID
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.
Mandatory
3
Time To Live
Indicates the number of seconds that the
neighbor
device
is
to
regard
the
local
information to be valid.
Mandatory
4
Port Description
Identifies the description string of the port.
Optional
5
System Name
Identifies the system name.
Optional
6
System
Description
Identifies the system description.
Optional

Address
Identifies the management IP address, the
corresponding
interface
number
and
OID
(Object Identifier). The management IP address
is specified by the user.
Optional
127
Organizationally
Specific
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.
Optional
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
