Getting Started

Restore the Factory Default Configuration

This section describes how to restore the factory default configuration. For the ASAv, this procedure erases

the deployment configuration and applies the same factory default configuration as for the ASA appliances.

Note

On the ASASM, restoring the factory default configuration simply erases the configuration; there is no

factory default configuration. On the Firepower 9300 ASA security module, restoring the factory default

configuration simply erases the configuration; to restore the default configuration, you must re-deploy the

ASA from the supervisor.

Before You Begin

This feature is available only in routed firewall mode; transparent mode does not support IP addresses for

interfaces. In addition, this feature is available only in single context mode; an ASA with a cleared configuration

does not have any defined contexts to configure automatically using this feature.

Procedure

Step 1

Restore the factory default configuration:

configure factory-default [ip_address [mask]]

Example:

ciscoasa(config)# configure factory-default 10.1.1.1 255.255.255.0

If you specify the ip_address, then you set the inside or management interface IP address, depending on your

model, instead of using the default IP address of 192.168.1.1. The http command uses the subnet you specify.

Similarly, the dhcpd address command range consists of addresses within the subnet that you specify.

This command also clears the boot system command, if present, along with the rest of the configuration. The

boot system command lets you boot from a specific image, including an image on the external flash memory

card. 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 2

Save the default configuration to flash memory:

write memory

This command saves the running configuration to the default location for the startup configuration, even if

you previously configured the boot config command to set a different location; when the configuration was

cleared, this path was also cleared.

Restore the ASAv Deployment Configuration

This section describes how to restore the ASAv deployment (Day 0) configuration.
