Firepower 7000 and 8000 Series Installation Guide
Chapter 5 Setting Up Firepower Managed Devices
Initial Setup Page: Firepower Devices
The Firepower System provides a dual stack implementation for both IPv4 and IPv6 management
environments. You must specify the management network protocol (
IPv4
,
IPv6
, or
Both
). Depending on
your choice, the setup page displays various fields where you must set the IPv4 or IPv6 management IP
address, netmask or prefix length, and default gateway:
•
For IPv4, you must set the address and netmask in dotted decimal form (for example: a netmask of
255.255.0.0).
•
For IPv6 networks, you can select 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).
You can also specify up to three DNS servers, as well as the host name and domain for the device.
Firepower Device LCD Panel Configuration
Select whether you want to allow changing of a Firepower device’s network settings using the LCD
panel.
Caution
Enabling this option can represent a security risk. You need only physical access, not authentication, to
configure network settings using the LCD panel. For more information, see
.
Remote Management
You must manage a Cisco device with a Firepower Management Center. In this two-step process, you
first configure remote management on the device, then add the device to a Firepower Management
Center. For your convenience, the setup page allows you to preregister the device to the Firepower
Management Center that will manage it.
Leave the
Register This Device Now
check box enabled, then specify the IP address or fully qualified
domain name of the managing Firepower Management Center as the
Management Host
. Also, type the
alphanumeric
Registration Key
you will later use to register the device to the Firepower Management
Center. Note that this is a simple key that you specify, up to 37 characters in length, and is not the same
as the license key.
Note
If the device and Firepower Management Center are separated by a network address translation (NAT)
device, defer device registration until after you complete the initial setup. See the Managing Devices
chapter in the
Firepower Management Center Configuration Guide
for more information.
Time Settings
You can set the time for a device either manually or via network time protocol (NTP) from an NTP
server, including the Firepower Management Center. Cisco recommends that you use the Firepower
Management Center as the NTP server for its managed devices.
You can also specify the time zone used on the local web interface for the
admin
account. Click the
current time zone to change it using a pop-up window.
