Configuring a Time to Live
The information received from a neighbor expires after a specific 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 specified physical interface.
To clear LLDP counters, enter the clear lldp counters command.
1. Clear counters for LLDP frames sent to and received from neighboring devices on all Aggregator interfaces or on a specified
interface.
interface specifies a 10GbE uplink port in the format: tenGigabitEthernet slot/port.
