The bootstrap package must include the basic configuration contained in the init-cfg.txt file in the /config folder; the complete configuration (contained in bootstrap.xml file in the /config folder) is optional. When you include both files in the bootstrap package, the firewall merges the configurations of those files and, if any configuration settings overlap between the two files, the firewall uses the setting defined in the init-cfg.txt file.
Basic Configuration—The init-cfg.txt file is a text file that contains basic initial configuration information. You can name this file generically as init-cfg.txt, or you can prepend the UUID or Serial number of each firewall to the filename to be more specific (for example: 0008C100105-init-cfg.txt). This file must include basic information for configuring the management interface on the firewall, such as the IP address type (static or DHCP), IP address (IPv4 only or both IPv4 and IPv6), netmask, and default gateway. The DNS server IP address, Panorama IP address and device group and template parameters are optional. When the firewall boots, it searches for a text file that matches its UUID or serial number and, if none is found, it searches using the generic filename. For a sample file, see Create the init-cfg.txt File.
For the VM-Series firewalls that you want to manage using Panorama, you must generate a VM auth key on Panorama and include the key in the init-cfg.txt file. For more information, see Generate the VM Auth Key on Panorama.
Complete Configuration—The bootstrap.xml file allows you to fully configure the firewall. The bootstrap.xml file is optional and is only required if you are not using Panorama for centrally managing your firewall. You can either define this manually or export the running configuration from an existing firewall and save the file as bootstrap.xml. If you include the bootstrap.xml file, make sure to export the XML file from a firewall of the same platform or hypervisor. If you provide the init-cfg.txt file and the bootstrap.xml file, the firewall merges the files into a running configuration as part of the bootstrap process and, if any settings overlap, the firewall will use the setting from the basic configuration file. See Create the bootstrap.xml File.
