Allowing Network Reconfiguration Using the LCD Panel
Because it presents a security risk, the ability to change network configuration using the LCD panel is
disabled by default. You can enable it during the initial setup process (see Understanding the Setup
Process, page 5-2), or using the device’s web interface as described in the following procedure.
To allow network reconfiguration using a device’s LCD panel:
Access: Admin
Step 1 After you complete the initial setup of the device, log into the device’s web interface using an account
with Administrator privileges.
Step 2 Select System > Local > Configuration.
The Information page appears.
Step 3 Click Network.
The Network Settings page appears.
Step 4 Under LCD Panel, select the Allow reconfiguration of network configuration check box. When the security
warning appears, confirm that you want to enable this option.
Tip For information on the other options on this page, see the Firepower Management Center Configuration
Guide.
Step 5 Click Save.
