Usage
Information
To delay the system from bringing up the VLT port for a brief period to allow IGMP snooping and Layer 3
routing protocols to converge, use the delay-restore command. Use this command:
● after a VLT device reloads.
● if the peer VLT device was up at the time the VLTi link failed.

Commands
● show vlt statistics — displays statistics on VLT operations.
delay-restore abort-threshold
Increase the boot up timer to a value greater than 60 seconds.
Syntax
delay-restore abort-threshold <interval>
To remove the boot up timer value, use the no delay-restore abort-threshold command.
Parameters
interval Enter the interval value (in seconds) for the delay restore timer to abort. The range
is from 1 to 1800 seconds. The default is 60 seconds.
This delay restore timer applies only during reload/boot-up and not in other
scenarios (for example, during ICL flap).
Defaults 60 seconds
