Guidelines for Fresh Installs

Reimaging Firepower 1000/2100 Series Devices to Earlier Major Versions

We recommend that you perform complete reimages of Firepower 1000/2100 series devices. If you use the erase configuration method, FXOS may not revert along with the Firepower Threat Defense software. This can cause failures, especially in high availability deployments.

For more information, see the reimage procedures in the Cisco FXOS Troubleshooting Guide for the Firepower 1000/2100 Series Running Firepower Threat Defense.

Reimage Checklist

Reimaging returns most settings to factory defaults, including the system password. This checklist highlights actions that can prevent common reimage issues. However, this checklist is not comprehensive. Refer to the appropriate installation guide for full instructions: Installation Instructions.

Action/Check

Check appliance access.

If you do not have physical access to an appliance, the reimage process lets you keep management network settings. This allows you to connect to the appliance after you reimage to perform the initial configuration. If you delete network settings, you must have physical access to the appliance. You cannot use Lights-Out Management (LOM).

Note

Reimaging to an earlier version automatically deletes network settings. In this rare case, you must have physical access.

For devices, make sure traffic from your location does not have to traverse the device itself to access the device's management interface. In Firepower Management Center deployments, you should also able to access the Firepower Management Center management interface without traversing the device.

Perform backups.

Back up before reimaging, when supported.

Note that if you are reimaging so that you don't have to upgrade, due to version restrictions you cannot use a backup to import your old configurations. You must recreate your configurations manually.

Caution

We strongly recommend you back up to a secure remote location and verify transfer success. Reimaging returns most settings to factory defaults, including the system password. It deletes any backups left on the appliance. And especially because backup files are unencrypted, do not allow unauthorized access. If backup files are modified, the restore process will fail.

Backup and restore can be a complex process. You do not want to skip any steps or ignore security or licensing concerns. For detailed information on requirements, guidelines, limitations, and best practices for backup and restore, see the configuration guide for your Firepower product.

Determine if you must remove devices from Firepower Management Center management.

If you plan to manually configure the reimaged appliance, remove devices from remote management before you reimage:

If you are reimaging the Firepower Management Center, remove all its devices from management.
If you are reimaging a single device or switching from remote to local management, remove that one device.

If you plan to restore from backup after reimaging, you do not need to remove devices from remote management.

Address licensing concerns.

Before you reimage any appliance, address licensing concerns. You may need to unregister from the Cisco Smart Software Manager (CSSM) to avoid accruing orphan entitlements, which can prevent you from reregistering. Or, you may need to contact Sales for new licenses.

For more information, see:

The configuration guide for your product.

Cisco Firepower System Feature Licenses Guide
Frequently Asked Questions (FAQ) about Firepower Licensing

Unregistering Smart Licenses

Firepower Threat Defense uses Cisco Smart Licensing. To use licensed features, register with Cisco Smart Software Manager (CSSM). If you later decide to reimage or switch management, you must unregister to avoid accruing orphan entitlements. These can prevent you from reregistering.

Note

If you need to restore an FMC or FTD device from backup, do not unregister before you reimage, and do not remove devices from the FMC. Instead, revert any licensing changes made since you took the backup. After the restore completes, reconfigure licensing. If you notice licensing conflicts or orphan entitlements, contact Cisco TAC.

Unregistering removes an appliance from your virtual account, unregisters it from the cloud and cloud services, and releases associated licenses so they can be can be reassigned. When you unregister an appliance, it enters Enforcement mode. Its current configuration and policies continue to work as-is, but you cannot make or deploy any changes.

Manually unregister from CSSM before you:

Reimage a Firepower Management Center that manages FTD devices.
Shut down the source Firepower Management Center during model migration.
Reimage a Firepower Threat Defense device that is locally managed by FDM.
Switch a Firepower Threat Defense device from FDM to FMC management.

Automatically unregister from CSSM when you remove a device from the FMC so you can:

Reimage an Firepower Threat Defense device that is managed by an FMC.
Switch a Firepower Threat Defense device from FMC to FDM management.

Note that in these two cases, removing the device from the FMC is what automatically unregisters the device. You do not have to unregister manually as long as you remove the device from the FMC.

Tip

Classic licenses for NGIPS devices are associated with a specific manager (ASDM/FMC), and are not controlled using CSSM. If you are switching management of a Classic device, or if you are migrating from an NGIPS deployment to an FTD deployment, contact Sales.
