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.
