Parameters
seconds: Sets the waiting time in seconds, in the range of 60 to 864000.
Usage guidelines
When a DHCP snooping entry is learned, updated, or removed, the waiting period starts. The DHCP
snooping device updates the backup file when the waiting period is reached. All changed entries
during the period will be saved to the backup file.
The waiting time does not take effect if you do not configure the DHCP snooping entry auto backup
by using the dhcp snooping binding database filename command.
Examples
# Set the waiting time to 600 seconds for the DHCP snooping device to update the backup file.
