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.

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
