Usage guidelines

When a DHCPv6 snooping entry is learned, updated, or removed, the waiting period starts. The DHCPv6 snooping device updates the backup file when the waiting period is reached. All snooping entries changed during the period will be saved to the backup file.

The waiting time does not take effect if you do not configure the DHCPv6 snooping entry auto backup by using the ipv6 dhcp snooping binding database filename command.

# Set the waiting time to 600 seconds for the DHCPv6 snooping device to update the backup file.
