TLV Type TLV Name Description Usage in LLDPDU 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 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 Different organizations have defined various TLVs. For instance, Port VLAN ID TLV, Port and Protocol VLAN ID TLV, VLAN Name TLV And Protocol Identity TLV are defined by IEEE 802.1, while MAC/PHY Configuration/Status TLV, Power Via MDI TLV, Link Aggregation TLV and Maximum Frame TLV are defined by IEEE 802.3. Note: For detailed introduction of TLV, please refer to IEEE 802.1AB standard. In TP-LINK switch, the following LLDP optional TLVs are supported. Port Description TLV The Port Description TLV allows network management to advertise the IEEE 802 LAN station's port description. System Capabilities TLV The System Capabilities TLV identifies the primary functions of the system and whether or not these primary functions are enabled. 321

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

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

Identifies the system name.
Optional
6
System

8
Management
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
Different organizations have defined various TLVs. For instance, Port VLAN ID TLV, Port and
Protocol VLAN ID TLV, VLAN Name TLV And Protocol Identity TLV are defined by IEEE 802.1,
while MAC/PHY Configuration/Status TLV, Power Via MDI TLV, Link Aggregation TLV and
Maximum Frame TLV are defined by IEEE 802.3.
Note:
For detailed introduction of TLV, please refer to IEEE 802.1AB standard.
In TP-LINK switch, the following LLDP optional TLVs are supported.
Port Description TLV
The Port Description TLV allows network management to
advertise the IEEE 802 LAN station's port description.
System Capabilities TLV
The System Capabilities TLV identifies the primary functions of
the system and whether or not these primary functions are
enabled.
