Cisco ASA 5500 Series Configuration Guide using ASDM
Chapter 2 Getting Started
Factory Default Configurations
Detailed Steps
Using the CLI:
Using ASDM:
Step 1 In the main ASDM application window, choose File > Reset Device to the Factory Default
Configuration.
The Reset Device to the Default Configuration dialog box appears.
Step 2 (Optional) Enter the Management IP address of the management interface, instead of using the default
address, 192.168.1.1. (For an ASA with a dedicated management interface, the interface is called
“Management0/0.”)
Command Purpose
Step 1
configure factory-default [ip_address
[mask]]
Example:
hostname(config)# configure
factory-default 10.1.1.1 255.255.255.0
Restores the factory default configuration.
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.
Note 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
write memory
Example:
active(config)# write memory
Saves the default configuration to flash 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.
