14.2.6 Schedule Writing of DHCP Snooping
Database Information to flash
DHCP Snooping provides a command that can be configured to schedule writing of DHCP
Snooping database information to the flash in order to prevent loss of DHCP user
information on the device due to restart of device following electricity failure. By default, the
time interval is 0, namely the information is not written to the flash regularly.
Command
Description
DGS-3610# configure terminal
Enter configuration mode
DGS-3610(config)# [no] ip dhcp snooping
database write-delay [time]
Set delay time of DHCP information written to
flash
time: 600s--86400s. Default value: 0
The following example demonstrates how to set the delay time of DHCP Snooping writing to
the flash to 3600s:
DGS-3610# configure terminal
DGS-3610(config)# ip dhcp snooping database write-delay 3600
DGS-3610(config)# end
DGS-3610#
Caution
You need to set a proper value for the time of delaying writing to the flash
since erasing and writing to the flash frequently shortens the life of the
flash. A shorter time helps to save the device information more
effectively. A longer time reduces the number of writing to the flash and
thus the flash has a longer life.
