Step 2

admin

as the username and

Admin123

as the password. (The password is case-sensitive.)

Step 3

In the

Change Password

section of the Setup page, change the password for the admin accounts. The admin

account for the web interface has Administrator privileges and cannot be deleted. We recommend that you
use a strong password that is at least eight alphanumeric characters of mixed case and includes at least one
numeric character. Avoid using words that appear in a dictionary.

The admin accounts for accessing a FMC through the shell as opposed to accessing a FMC using
the web interface are not the same, and may use different passwords. This setting changes both
admin passwords to the same value.

Note

Step 4

The FMC’s network settings allow it to communicate on your management network. Configure these settings
in the

Network Settings

section of the Setup page:

• If you already configured the network settings for appliance access using a keyboard and monitor, the

Network Settings

section of the Setup page may be prepopulated.

• If values are not prepopulated under

Network Settings

, or if you want to change the prepopulated values,

you must choose the management network protocol. The Firepower system provides a dual stack
implementation for both IPv4 and IPv6 management environments; you can specify IPv4, IPv6, or Both.

Depending on your protocol choice, the Setup page displays fields where you must enter the IPv4 or
IPv6 management IP address, netmask or prefix length, and default gateway for the FMC. You can also
specify up to three DNS servers, as well as the host name and domain for the device.

• For IPv4, you must enter the address and netmask in dotted decimal form (for example, a netmask

of 255.255.0.0).

• For IPv6 networks, check the

Assign the IPv6 address using router autoconfiguration

check box

to automatically assign IPv6 network settings. Otherwise, you must set the address in colon-separated
hexadecimal form and the number of bits in the prefix (for example, a prefix length of 112).

Step 5

(Optional) In the

Time Settings

section of the Setup page you can set the time for a FMC one of two ways:

either manually or using the network time protocol (NTP) from an NTP server.

• To set the time using network time protocol (NTP), select

Via NTP from

and specify one or more NTP

servers the FMC can access.

• To set the time manually, select

Manually

and enter the current time in the provided fields.

To choose the time zone used on the local web interface for the admin account, click the current time zone
value and choose a time zone from the pop-up window.

Using an NTP server is critial to ensure proper time synchronization between the FMC and its
managed devices. If you do not configure an NTP server during the initial setup process, we strongly
recommend you do so as soon as possible. See the Time and Time Synchronization section in the

Firepower Management Center Configuration Guide

for your version for more information.

Note

Step 6

(Optional) If you plan to perform intrusion detection and prevention in your deployment, in the

Recurring

Rule Update Imports

section of the Setup page, we recommend that you check

Enable Recurring Rule

Update Imports from the Support Site

You can specify the

Import Frequency
