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 connected

Mandatory

 

 

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.

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. Some specific TLVs are for LLDP-MED protocol, such as LLDP-MED Capabilities TLV, Network Policy TLV, Extended Power-via-MDI TLV, Hardware Revision TLV and so on.
