Note:
The lease information is not saved in the DHCP server's Flash when you execute the
save command. So there is not any lease information in the configuration files when the
system restarts or when you use the reset dhcp server ip-in-use command to delete the
lease information. If a client requests lease renewal at this time, the system will not
permit it but require the client to apply for the IP address again.
