Usage guidelines
The DHCP server does not provide services during the binding download process. If the connection
disconnects during the process, the waiting timeout timer is 60 minutes. When the timer expires, the
DHCP server stops waiting and starts providing address allocation services.
To enable the DHCP server to provide services without waiting for the connection to be repaired, use
this command to terminate the download immediately. The IP addresses associated with the
undownloaded bindings will be assigned to clients. Address conflicts might occur.
Examples
# Terminate the download of the backup DHCP bindings.
<Sysname> system-view
[Sysname] dhcp server database update stop
