Chapter 2 Getting Started
Factory Default Configurations
Step 3 (Optional) Choose the Management Subnet Mask from the drop-down list.
Step 4 Click OK.
A confirmation dialog box appears.
Note This action also clears the location of the boot image location, if present, along with the rest of
the configuration. The Configuration > Device Management > System Image/Configuration >
Boot Image/Configuration pane lets you boot from a specific image, including an image on the
external memory. The next time you reload the ASA after restoring the factory configuration, it
boots from the first image in internal flash memory; if you do not have an image in internal flash
memory, the ASA does not boot.
Step 5 Click Yes.
Step 6 After you restore the default configuration, save this configuration to internal flash memory. Choose File
> Save Running Configuration to Flash.
Choosing this option saves the running configuration to the default location for the startup configuration,
even if you have previously configured a different location. When the configuration was cleared, this
path was also cleared.
