Cable and Register the Firewall

Cable the firewall and then register the firewall to the management center.

Cable the Firewall

  • Obtain a console cable—The firewall does not ship with a console cable by default, so you will need to buy a third-party USB-to-RJ-45 serial cable, for example.

  • Install SFPs into the data interface ports—The built-in ports are 1/10/25-Gb SFP28 ports that require SFP/SFP+/SFP28 modules.

  • See the hardware installation guide for more information.

Cabling for a Management Center at a Central Headquarters

Perform Initial Configuration (Manual Provisioning)

For manual provisioning, perfom initial configuration of the firewall using the Secure Firewall device manager or using the CLI.

Initial Configuration: Device Manager

Using this method, after you register the firewall, the following interfaces will be preconfigured in addition to the Management interface:

  • Ethernet 1/1—outside, IP address from DHCP, IPv6 autoconfiguration

  • — inside, 192.168.95.1/24

  • Default route—Obtained through DHCP on the outside interface

  • Additional interfaces—Any interface configuration from the device manager is preserved.

Other settings, such as the DHCP server on inside, access control policy, or security zones, are not preserved.

Procedure

Step 1

Connect your computer to the inside interface.

Step 2

Log into the device manager.

  1. Go to https://192.168.95.1.

  2. Log in with the username admin and the default password Admin123.

  3. You are prompted to read and accept the General Terms and change the admin password.

Step 3

Use the setup wizard.

Note

 

The exact port configuration depends on your model.

  1. Configure the outside and management interfaces.

    Figure 1. Connect firewall to internet
    Connect firewall to internet

    1. Outside Interface Address—Use a static IP address if you plan for high availability. You cannot configure PPPoE using the setup wizard; you can configure PPPoE after you complete the wizard.

    2. Management Interface—The Management interface settings are used even though you are using manager access on the outside interface. For example, management traffic that is routed over the backplane through the outside interface will resolve FQDNs using these Management interface DNS servers, and not the outside interface DNS servers.

      DNS Servers—The DNS server for the system's management address. The default is the OpenDNS public DNS servers. These will probably match the outside interface DNS servers you set later since they are both accessed from the outside interface.

  2. Configure the Time Setting (NTP) and click Next.

    Figure 2. Time Setting (NTP)
    Connect firewall to internet

  3. Select Start 90 day evaluation period without registration.

    Connect firewall to internet

    Do not register the threat defense with the Smart Software Manager; all licensing is performed on the management center.

  4. Click Finish.

    Figure 3. What's Next
    Connect firewall to internet

  5. Choose Standalone Device, and then Got It.

Step 4

If you want to configure additional interfaces, choose Device, and then click the link in the Interfaces summary.

Step 5

Register with the management center by choosing Device > System Settings > Central Management and clicking Proceed

Configure the Management Center/CDO Details.

Figure 4. Management Center/CDO Details
Management Center/CDO Details

  1. For Do you know the Management Center/CDO hostname or IP address, click Yes if you can reach the management center using an IP address or hostname or No if the management center is behind NAT or does not have a public IP address or hostname.

  2. If you chose Yes, enter the Management Center/CDO Hostname/IP Address.

  3. Specify the Management Center/CDO Registration Key.

    This key is a one-time registration key of your choice that you will also specify on the management center when you register the firewall. The registration key must not exceed 37 characters. Valid characters include alphanumerical characters (A–Z, a–z, 0–9) and the hyphen (-). This ID can be used for multiple firewalls registering to the management center.

  4. Specify a NAT ID.

    This ID is a unique, one-time string of your choice that you will also specify on the management center. We recommend that you specify the NAT ID even if you know the IP addresses of both devices. The NAT ID must not exceed 37 characters. Valid characters include alphanumerical characters (A–Z, a–z, 0–9) and the hyphen (-). This ID cannot be used for any other firewalls registering to the management center. The NAT ID is used in combination with the IP address to verify that the connection is coming from the correct device; only after authentication of the IP address/NAT ID will the registration key be checked.

Step 6

Configure the Connectivity Configuration.

  1. Specify the Threat Defense Hostname.

    This FQDN will be used for the outside interface.

  2. Specify the DNS Server Group.

    Choose an existing group, or create a new one. The default DNS group is called CiscoUmbrellaDNSServerGroup, which includes the OpenDNS servers.

    To retain the outside DNS server setting after registration, you need to re-configure the DNS Platform Settings in the management center.

  3. For the Management Center/CDO Access Interface, click Data Interface, and then choose outside.

Step 7

(Optional) Click Add a Dynamic DNS (DDNS) method.

DDNS ensures the management center can reach the threat defense at its FQDN if the threat defense's IP address changes.

Step 8

Click Connect.

The Registration Status dialog box shows the current status of the management center registration.

Figure 5. Successful Connection
Successful Connection

Step 9

After the Saving Management Center/CDO Registration Settings step on the status screen, go to the management center and add the firewall. See Register the Firewall with the Management Center Using Manual Provisioning.

Initial Configuration: CLI

Set the dedicated Management IP address, gateway, and other basic networking settings using the CLI setup script.

Procedure

Step 1

Connect to the console port and access the threat defense CLI. See Access the Threat Defense CLI.

Step 2

Complete the CLI setup script for the Management interface settings.

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 Cisco Secure Firewall Threat Defense Command Reference.

You can register the sensor to a Firepower Management Center and use the
Firepower Management Center to manage it. Note that registering the sensor
to a Firepower Management Center disables on-sensor Firepower Services
management capabilities.

When registering the sensor to a Firepower Management Center, a unique
alphanumeric registration key is always required.  In most cases, to register
a sensor to a Firepower Management Center, you must provide the hostname or
the IP address along with the registration key.
'configure manager add [hostname | ip address ] [registration key ]'

However, if the sensor and the Firepower Management Center are separated by a
NAT device, you must enter a unique NAT ID, along with the unique registration
key.
'configure manager add DONTRESOLVE [registration key ] [ NAT ID ]'

Later, using the web interface on the Firepower Management Center, you must
use the same registration key and, if necessary, the same NAT ID when you add
this sensor to the Firepower Management Center.

Step 3

Configure the outside interface for manager access.

configure network management-data-interface

You are then prompted to configure basic network settings for the outside interface.

>

Step 4

Identify the management center.

configure manager add {hostname | IPv4_address | IPv6_address | DONTRESOLVE} reg_key nat_id

  • {hostname | IPv4_address | IPv6_address | DONTRESOLVE}—Specifies either the FQDN or IP address of the management center. If the management center is not directly addressable, use DONTRESOLVE, in which case the firewall must have a reachable IP address or hostname.

  • reg_key—Specifies a one-time registration key of your choice that you will also specify on the management center when you register the threat defense. The registration key must not exceed 37 characters. Valid characters include alphanumerical characters (A–Z, a–z, 0–9) and the hyphen (-).

  • nat_id—Specifies a unique, one-time string of your choice that you will also specify on the management center. The NAT ID must not exceed 37 characters. Valid characters include alphanumerical characters (A–Z, a–z, 0–9) and the hyphen (-). This ID cannot be used for any other devices registering to the management center.

Example:


> configure manager add fmc-1.example.com regk3y78 natid56
Manager successfully configured.

Step 5

Shut down the threat defense so you can send the device to the remote branch office.

It's important that you shut down your system properly. Simply unplugging the power or pressing the power switch can cause serious file system damage. Remember that there are many processes running in the background all the time, and unplugging or shutting off the power does not allow the graceful shutdown of your system.

  1. Enter the shutdown command.

  2. Observe the Power LED and Status LED to verify that the chassis is powered off (appear unlit).

  3. After the chassis has successfully powered off, you can then unplug the power to physically remove power from the chassis if necessary.

Register the Firewall with the Management Center

Register the firewall with the management center depending on which deployment method you are using.

Add the Firewall to the Management Center Using Zero-Touch Provisioning

Zero-Touch Provisioning lets you register devices to the management center by serial number without having to perform any initial setup on the device. The management center integrates with the Cisco Security Cloud and CDO for this functionality.

When you use zero-touch provisioning, the following interfaces are preconfigured. Note that other settings, such as the DHCP server on inside, access control policy, or security zones, are not configured.

  • Ethernet 1/1—"outside", IP address from DHCP, IPv6 autoconfiguration

  • Ethernet 1/2 (or for the , the VLAN1 interface)— "inside", 192.168.95.1/24

  • Default route—Obtained through DHCP on the outside interface

High availability is only supported when you use the Management interface because zero-touch provisioning uses DHCP, which is not supported for data interfaces and high availability.


Note

For management center version 7.4, you need to add the device using CDO; see the 7.4 guide for more information. The native management center workflow was added in 7.6. Also, for cloud integration in 7.4, see the SecureX Integration page in the management center.

Before you begin

  • If the device does not have a public IP address or FQDN, set a public IP address/FQDN for the management center (for example, if it is behind NAT), so the device can initiate the management connection. See .

Procedure

Step 1

The first time you add a device using a serial number, integrate the management center with Cisco Security Cloud.

Note

 

For a management center high-availability pair, you also need to integrate the secondary management center with Cisco Security Cloud.

  1. Choose Integration > Cisco Security Cloud.

  2. Click Enable Cisco Security Cloud to open a separate browser tab to log you into your Cisco Security Cloud account and confirm the displayed code.

    Make sure this page is not blocked by a pop-up blocker. If you do not already have a Cisco Security Cloud and CDO account, you can add one during this procedure.

    For detailed information about this integration, see .

    CDO onboards the on-prem management center after you integrate the management center with Cisco Security Cloud. CDO needs the management center in its inventory for zero-touch provisioning to operate. However, you do not need to use CDO directly. If you do use CDO, its management center support is limited to device onboarding, viewing its managed devices, viewing objects associated with the management center, and cross-launching the management center.

  3. Make sure Enable Zero-Touch Provisioning is checked.

  4. Click Save.

Step 2

Choose Devices > Device Management.

Step 3

From the Add drop-down menu, choose Device (Wizard).

Step 4

Click Use Serial Number, and then click Next.

Figure 6. Device Registration Method
Device Registration Method

Step 5

For the Initial device configuration, click the Basic radio button.

Figure 7. Initial Device Configuration Method
Registration Type

  1. Choose an initial Access Control Policy to deploy to the device upon registration, or create a new policy.

    If the device is incompatible with the policy you choose, deploying will fail. This incompatibility could occur for multiple reasons, including licensing mismatches, model restrictions, passive vs inline issues, and other misconfigurations. After you resolve the issue that caused the failure, manually deploy configurations to the device.

  2. Choose Smart licensing licenses to apply to the device.

    You can also apply licenses after you add the device, from the System > Licenses > Smart Licenses page.

  3. Click Next.

Step 6

Configure the Device details.

Figure 8. Device details
Connection Settings

  1. Enter the Serial number.

  2. Enter the Display name as you want it to display in the management center

  3. (Optional) Choose the Device Group.

  4. Set the device password.

    If this device is unconfigured or a fresh install, then you need to set a new password. If you already logged in and changed the password, then leave this field blank. Otherwise, registration will fail.

Step 7

Click Add Device.

It may take up to two minutes for the management center to verify the device’s heartbeat and establish communication. If the registration succeeds, the device is added to the list.

Register the Firewall with the Management Center Using Manual Provisioning

Register the firewall to the management center.

Procedure

Step 1

Log into the management center.

  1. Enter the following URL.

    https://fmc_ip_address

  2. Enter your username and password.

  3. Click Log In.

Step 2

Choose Devices > Device Management.

Step 3

From the Add drop-down list, choose Add Device.

Figure 9. Add Device Using a Registration Key
Add Device Using a Registration Key

Set the following parameters:

  • Host—Enter the IP address or hostname of the firewall you want to add, if available. Leave this field blank if it is not available.

  • Display Name—Enter the name for the firewall as you want it to display in the management center. You cannot change this name later.

  • Registration Key—Enter the same registration key that you specified in the firewall initial configuration.

  • Domain—Assign the device to a leaf domain if you have a multidomain environment.

  • Group—Assign it to a device group if you are using groups.

  • Access Control Policy—Choose an initial policy. Unless you already have a customized policy you know you need to use, choose Create new policy, and choose Block all traffic. You can change this later to allow traffic; see Configure an Access Control Rule.

    Figure 10. New Policy
    New Policy

  • Smart Licensing—Assign the Smart Licenses you need for the features you want to deploy. Note: You can apply the Secure Client remote access VPN license after you add the device, from the System > Licenses > Smart Licenses page.

  • Unique NAT ID—Specify the NAT ID that you specified in the firewall initial configuration.

  • Transfer Packets—Check the Transfer Packets check box so that for each intrusion event, the device transfers the packet to the management center for inspection.

    This option is enabled by default. For each intrusion event, the device sends event information and the packet that triggered the event to the management center for inspection. If you disable it, only event information will be sent to the management center; the packet will not be sent.

Step 4

Click Register.

If the threat defense fails to register, check the following items:

  • Ping—Access the threat defense CLI (see Access the Threat Defense CLI), and ping the management center IP address using the following command:

    ping system fmc_ip_address

    If the ping is not successful, check your network settings using the show network command. If you need to change the firewall Management IP address, use the configure network management-data-interface command.

  • Registration key, NAT ID, and the management center IP address—Make sure you are using the same registration key and NAT ID on both devices. You can set the registration key and NAT ID on the firewall using the configure manager add command.
