(Optional) Change Management Network Settings At The Cli - Cisco Firepower 2100 Series Getting Started Manual

Firepower Threat Defense Deployment with FDM
Note

(Optional) Change Management Network Settings at the CLI

If you cannot use the default management or inside IP address (for example, you are adding your device to
an existing network), then you can connect to the console port and perform initial setup at the CLI, including
setting the Management IP address, gateway, and other basic networking settings. You can only configure
the Management interface settings; you must configure data interface settings in FDM.
Note You cannot repeat the CLI setup script unless you clear the configuration; for example, by reimaging. However,
all of these settings can be changed later at the CLI using configure network commands. See the
command
Procedure
Step 1
Connect to the FTD console port. See
Step 2 Log in with the username admin and the password Admin123.
Step 3
The first time you log in to FTD, you are prompted to accept the End User License Agreement (EULA) and
to change the admin password. You are then presented with the CLI setup script.
Defaults or previously-entered values appear in brackets. To accept previously entered values, press Enter.
See the following guidelines:
• Enter the IPv4 default gateway for the management interface—Enter either data-interfaces or the
• If your networking information has changed, you will need to reconnect—If you are connected with
• Manage the device locally?—Enter yes to use FDM. A no answer means you will use FMC instead.
Example:
You must accept the EULA to continue.
Press <ENTER> to display the EULA:
When the switch is toggled from ON to OFF, it may take several seconds for the system to eventually
power off. During this time, the PWR LED on the front of the device blinks green. Do not remove
the power until the PWR LED is completely off.
reference.
IP address of the gateway router. The data-interfaces setting sends outgoing management traffic over
the backplane to exit a data interface. This setting is useful if you do not have a separate Management
network that can access the internet. Traffic originating on the Management interface includes license
registration and database updates that require internet access. If you use data-interfaces, you can still
use FDM on the Management interface if you are directly-connected to the Management network, but
for remote management on Management, you need to enter the IP address of a gateway router on the
Management network. Note that FDM management on data interfaces is not affected by this setting.
SSH to the default IP address but you change the IP address at initial setup, you will be disconnected.
Reconnect with the new IP address and password. Console connections are not affected. Note also that
the DHCP server on Management will be disabled if you change the IP address.
