With this command executed, the DHCPv6 snooping device backs up its snooping entries
immediately and runs auto backup. The snooping device, by default, waits 300 seconds after a
DHCPv6 snooping entry change to update the backup file. You can use the ipv6 dhcp snooping
binding database update interval command to change the waiting time. If no DHCPv6 snooping
entry changes, the backup file is not updated.
When the file is on a remote device, follow these restrictions and guidelines to specify the URL,
username, and password:
