• Type indicates the nature of information being transmitted.
• Length indicates the length of the information string in octets.
• Value is the actual information that is transmitted. (For example, a binary bit map
or an alphanumeric string that can contain one or more fields).
Each LLDPDU contains four mandatory TLVs and optional TLVs selected by the
Network Management. The following is the format of an LLDPDU:
• Chassis ID TLV
• Port ID TLV
• Time To Live (TTL) TLV
• zero or more optional TLVs, depending on the maximum size of the LLDPDU
allowed
• End of LLDPDU TLV
A concatenated string formed by the Chassis ID TLV and the Port ID TLV is used by
a recipient to identify an LLDP port or agent. The combination of the Port ID and
Chassis ID TLVs remains unchanged until the port or agent is operational.
The TTL field of a Time-To-Live TLV can be a zero or non-zero value. A zero TTL
field value notifies the receiving LLDP agent to immediately discard all information
related to sending LLDP agent. A non-zero TTL field value indicates the time duration
for which the receiving LLDP agent should retain the information of the sending LLDP
agent. The receiving LLDP agent discards all information related to the sending
LLDP agent after the time interval indicated in the TTL field is complete.
The End Of LLDPDU TLV indicates the end of the LLDPDU.
The following information is included in the protocol as defined by the IEEE 802.1ab
standard.
• Connectivity and management information about the local station to adjacent
stations on the same IEEE 802 LAN is advertised.
• Network management information from adjacent stations on the same IEEE 802
LAN is received.
• It operates with all IEEE 802 access protocols and network media.
• Network management information schema and object definitions suitable for
storing connection information about adjacent stations is established.
Note: A TTL zero value is used to signal that the sending LLDP port has initiated a port
shutdown procedure.
