Use these instructions to create the optional bootstrap.xml file.
Create the bootstrap.xml File
Export a configuration from a firewall. Select Device > Setup > Operations. Select the configuration file you want to export. To export the running configuration, in the Configuration Management section, Export named configuration snapshot and select running config.xml from the drop-down. To export a previous version of a firewall configuration, in the Configuration Management section, Export configuration version and select the appropriate configuration version in the drop-down.
Rename the configuration file as bootstrap.xml. Rename the file as bootstrap.xml. For the bootstrap process to be successful, the filename must be an exact (case-sensitive) match. Save the bootstrap.xml file in the same location as the init-cfg.txt file.
