Configuring DHCP binding auto backup

The auto backup feature saves bindings to a backup file and allows the DHCP server to download
the bindings from the backup file at the server reboot. The bindings include the lease bindings and
conflicted IP addresses. They cannot survive a reboot on the DHCP server.
The DHCP server does not provide services during the download process. If a connection error
occurs during the process and cannot be repaired in a short amount of time, you can terminate the
download operation. Manual interruption allows the DHCP server to provide services without waiting
for the connection to be repaired.
To configure DHCP binding auto backup:
Step
1. Enter system view.
2. Configure the DHCP server to
back up the bindings to a file.
3. (Optional.) Manually save the
DHCP bindings to the backup
file.
