Configuring Automatic Saving of DHCP Data

You can configure the S3328TP-EI-24S  to save DHCP data to the storage device. When a fault occurs, you can restore data from the storage device.

Run:

system-view

The system view is displayed.

Run:

dhcp server database enable

The S3300 automatically saves DHCP data to the flash memory.

After the dhcp server database enable command is executed, the system generates the lease.txt and conflict.txt files in the flash. The two files save the address lease information and address conflict information.

Run:

dhcp server database write-delay interval

The interval for saving DHCP data is set.

By default, DHCP data is not automatically saved to flash. After the S3300 is configured to automatically save DHCP data, the S3300 saves data every 7200 seconds by default and the latest data overwrites the previous data.

Run:

dhcp server database recover

The DHCP data in the storage device is restored.

After the dhcp server database recover command is executed, the Huawei S3300  restores the DHCP data in the flash.
