Step 5 Answer the prompts to configure network settings.
When following the prompts, for multiple-choice questions, your options are listed in parentheses, such as
(y/n). Defaults are listed in square brackets, such as [y]. Note the following when responding to prompts:
• If you are setting up an appliance after restoring it to factory defaults (see About the Restore Process, on
page 50) and you did not delete the appliance's license and network settings, the prompts will be
pre-populated with the retained values.
• Press Enter to accept the default.
• For hostname, supply a fully qualified domain name (<hostname>.<domain>) or host name. This field
is required.
• If you choose to configure IPv4 manually, the system prompts for IPv4 address, netmask, and default
gateway. If you choose DHCP, the system uses DHCP to assign these values. If you choose not to use
DHCP, you must supply values for these fields; use standard dotted decimal notation.
• Configuring a DNS server is optional; to specify no DNS server enter none. Otherwise specify IPv4
addresses for one or two DNS servers. If you specify two addresses, separate them with a comma. (If
you specify more than two DNS servers, the system ignores the additional entries.) If your management
center does not have internet access you cannot use a DNS outside of your local network.
If you are using an evaluation license, specifying DNS is optional at this time, but DNS is
required to use permanent licenses for your deployment.
Note
• You must enter the fully qualified domain name or IP address for at least one NTP server reachable from
your network. (You may not specify FQDNs for NTP servers if you are not using DHCP.) You may
specify two servers (a primary and a secondary); separate their information with a comma. (If you specify
more than two DNS servers, the system ignores the additional entries.) If your management center does
not have internet access you cannot use an NTP server outside of your local network.
Example:
Enter a hostname or fully qualified domain name for this system [firepower]: fmc
Configure IPv4 via DHCP or manually? (dhcp/manual) [DHCP]: manual
Enter an IPv4 address for the management interface [192.168.45.45]: 10.10.0.66
Enter an IPv4 netmask for the management interface [255.255.255.0]: 255.255.255.224
Enter the IPv4 default gateway for the management interface [ ]: 10.10.0.65
Enter a comma-separated list of DNS servers or 'none' [CiscoUmbrella]:
208.67.222.222,208.67.220.220
Enter a comma-separated list of NTP servers [0.sourcefire.pool.ntp.org,
1.sourcefire.pool.ntp.org]:
Step 6 The system displays a summary of your configuration selections. Review the settings you have entered.
Example:
Hostname: fmc
IPv4 configured via: manual configuration
Management interface IPv4 address: 10.10.0.66
Management interface IPv4 netmask: 255.255.255.224
Management interface IPv4 gateway: 10.10.0.65
DNS servers: 208.67.222.222,208.67.220.220
NTP servers: 0.sourcefire.pool.ntp.org, 1.sourcefire.pool.ntp.org
Step 7 The final prompt gives you the opportunity to confirm the settings.
• If the settings are correct, enter yand press Enter to accept the settings and continue.
