System Maintenance

This chapter introduces how to do system maintenance.

30.1 Demands

1. DFL-1500 is designed to provide upgradeable firmware and database to meet the upcoming dynamics of the Internet. New

features, new attack signatures and new forbidden URLs require timely updates to the DFL-1500. This chapter introduces

how to upgrade your system with TFTP and Web UI respectively.

2. Sometimes one may want to reset the firmware to factory default due to loss of password, firmware corrupted,

configuration corrupted. Since DFL-1500 does not have a reset button to prevent careless pressing of it, factory default has

to be set with web GUI or console terminal. Of course, when you loss the password, you have to use CLI only because you

can never enter the web GUI with the lost password.

3. Another issue is that after setup the DFL-1500 properly, we might want to keep the current configuration to avoid the

unknown accident. Then we can recover the original state from the previous reserved configuration.
