One such example is during a deployment I encountered a Cisco Bug for FTD version 7.0.4 locally managed by FDM. The bug caused a corruption in the database that cannot be repair and configurations from the FDM are not synced with the LINA, the ASA portion of the FTD. There were discrepancies between the configuration in the CLI and the FDM. The options are to reset to factory default or reimage the FTD. This document focusses on resetting the FTD back to factory default and applies to FTD 1000 series of appliances.   ## Resetting FMC Managed FTDs If the FTD is managed by FMC, the easiest and fastest way to reset the device is to remove the manager or switch firewall mode from CLI.   This will delete all the configurations pushed down from the FMC and set the device back to factory. However, I do not know if the database actually gets rebuilt or just get erased. So, this may not fix the issues with database corruption.   To delete the manager and reset the appliance to default: ***> configure manager delete***   To reset the appliance to default by changing firewall modes **>*configure firewall?*** * routed       Change to routed firewall mode* * transparent Change to transparent firewall mode*   Resetting FDM managed FTDs Resetting the FTD to factory default will erase all configurations and settings. It is recommended that a backup of the configuration is performed and downloaded from the FDM to a workstation for local storage. After the factory reset the configuration can then be restored from the FDM. This will fixed the database corruption issue as it deletes the old database and start with a new database. 1. **Power cycle the appliance and hit Break or ESC during boot up to access ROMMON.**   *Rebooting...

Look for the serial number of the FTD and remove it from Product Instances.   ![Resetting a Cisco FTD appliance back to factory default](https://www.lookingpoint.com/hs-fs/hubfs/undefined-Sep-27-2022-06-59-30-23-PM.png?width=600&name=undefined-Sep-27-2022-06-59-30-23-PM.png) Generate a new token and apply it in the FDM to license the FTD. ![Resetting a Cisco FTD appliance back to factory default](https://www.lookingpoint.com/hs-fs/hubfs/undefined-Sep-27-2022-07-04-23-83-PM.png?width=400&height=234&name=undefined-Sep-27-2022-07-04-23-83-PM.png)   As always if you have any questions on Cisco FTD for you and your business and would like to schedule a free consultation with us, please reach out to us at [sales@lookingpoint.com](mailto:sales@lookingpoint.com) and we’ll be happy to help!
