Use this command to configure the switch to write the dynamic user information of the DHCP snooping
binding database into the flash periodically. The no form of this command will disable this function.

This function can avoid loss of user information after restart. In that case,
users need to obtain IP addresses again for normal communication.

user information into the flash as 3600s:
Ruijie# configure terminal
Ruijie(config)# ip dhcp snooping database write-delay 3600
Ruijie(config)# end
Ruijie# show ip dhcp snooping
