Automatic backup of DHCP snooping binding table on S series switch

For S series switches in V200R003C00 and later versions, you can run the dhcp snooping user-bind autosave file-name [ write-delay delay-time ] command to enable automatic backup of the DHCP snooping binding table and specify the backup interval. By default, local automatic backup of the DHCP snooping binding table is disabled.
By default, S series modular switches and fixed switches back up the DHCP snooping binding table every 1 hour and every 24 hours, respectively.
