Conguring a Time to Live
The information received from a neighbor expires after a specic amount of time (measured in seconds) called a time to live (TTL).
The TTL is the product of the LLDPDU transmit interval (hello) and an integer called a multiplier. The default multiplier is 4, which results in
a default TTL of 120 seconds.
• Adjust the TTL value.

Clearing LLDP Counters
You can clear LLDP statistics that are maintained on an Aggregator for LLDP counters for frames transmitted to and received from
neighboring devices on all or a specied physical interface.
To clear LLDP counters, enter the clear lldp counters command.
