TTL value
The Time to Live (TTL) Value is the length of time the receiving device should maintain the
information acquired by LLDP in its MIB.

The TTL value is automatically computed based on the LLDP configuration settings. The TTL value
will appear similar to the following on the remote device, and in the CLI display output on the device
(show lldp local-info).

Time to live: 40 seconds

If the TTL field has a value other than zero, the receiving LLDP agent is notified to completely
replace all information associated with the LLDP agent/port with the information in the received
LLDPDU.

If the TTL field value is zero, the receiving LLDP agent is notified that all system information
associated with the LLDP agent/port is to be deleted. This TLV may be used, for example, to signal
that the sending port has initiated a port shutdown procedure.

The LLDPDU format is shown in

“LLDPDU packet format”

on page 190.

The TTL TLV format is shown below.
