What to Do Next
See the “Working with the Configuration” section on page 1-23 to start configuring the ASA.
ASA 5505 Default Configuration
The default configuration is available for routed mode only. This section describes the default
configuration and also provides a sample transparent mode configuration that you can copy and paste as
a starting point. This section includes the following topics:
• ASA 5505 Routed Mode Default Configuration, page 1-19
• ASA 5505 Transparent Mode Sample Configuration, page 1-21
ASA 5505 Routed Mode Default Configuration
The default factory configuration for the ASA 5505 configures the following:
• Interfaces—Inside (VLAN 1) and outside (VLAN 2).
• Switchports enabled and assigned—Ethernet 0/1 through 0/7 switch ports assigned to inside.
Ethernet 0/0 assigned to outside.
• IP addresses— Outside address from DHCP; inside address set manually to 192.168.1.1/24.
• Network address translation (NAT)—All inside IP addresses are translated when accessing the
outside using interface PAT.
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.
