Link Layer Discovery Protocol (LLDP) | 329
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. To 
adjust the TTL value—at CONFIGURATION level or INTERFACE level—use the 
multiplier command. To 
return to the default multiplier value, use the 
no multiplier command (Figure 18-15).
