Configuring LLDPDU Intervals
LLDPDUs are transmitted periodically; the default interval is 30 seconds.
To configure LLDPDU intervals, use the following command.
• Configure a non-default transmit interval.
CONFIGURATION mode or INTERFACE mode
hello
Example of Viewing LLDPDU Intervals
Dell#conf
Dell(conf)#protocol lldp
Dell(conf-lldp)#show config
!
protocol lldp
Dell(conf-lldp)#hello ?
<5-180> Hello interval in seconds (default=30)
Dell(conf-lldp)#hello 10
Dell(conf-lldp)#show config
!
protocol lldp
hello 10
Dell(conf-lldp)#
Dell(conf-lldp)#no hello
Dell(conf-lldp)#show config
!
protocol lldp
Dell(conf-lldp)#
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.
CONFIGURATION mode or INTERFACE mode.

• Return to the default multiplier value.
CONFIGURATION mode or INTERFACE mode.
