Factory reset

WARNING: Performing a factory reset will remove all logs and configuration.

Using Image:
   (X) panos-4.1.6

< Factory Reset                                                                >

You enter factory reset to restore the firewall to factory default, there was a scrub option however I think it is in Advanced option, the scrub will erase everything including PanOS. The Advanced option is password protected which I think is a great idea, if a reset with scrub is really necessary it should be done by Palo Alto Networks Engineers and not the users. If the PanOS is erased the firewall has to be sent for RMA anyway.

Factory reset completed

Factory reset completed

Content Rollback
This option is to revert to the previous PanOS you have installed. This can be done safely over the web user interface.

    Does a factory reset remove any licenses that are installed as is the case with buying an appliance second hand and not knowing the login/password? Thanks in advance.

  2. Roh says:

    Yes, Factory Reset would remove all license that are installed and login/password.

  3. From maint could it be posible to change one of the Interfaces MAC Address
