This procedure describes how to restore configuration changes made to an ASA using Cisco Defense Orchestrator (CDO). This is a convenient way to remove a configuration change that had unexpected or undesired results.
Before You Restore a Configuration
Review these notes before restoring a configuration:
- CDO compares the configuration you choose to restore with the last known configuration written to the ASA, it does not compare the configuration you choose to restore with a configuration that is staged but not written to the ASA's memory. If you have any unwritten changes on your ASA and you restore a previous configuration, the restore process will overwrite your unwritten changes and you will lose them.
- Restoring a past configuration overwrites all intermediate written configurations changes. For example, restoring the configuration from 07/11/2017 in the list below overwrites the configuration changes made on 7/13/2017.
- If you originally applied a change request label to your configuration changes, that label appears in the Restore Configuration list.
- Before you can restore a past configuration, the ASA can be in a Synced or Not Synced state but you must resolve any configuration conflicts before you restore a past configuration.
How to Restore a Configuration
- Open the Devices & Services page.
- Select the ASA whose configuration you want to restore.
- Select Configuration > Restore Configuration in the right pane.
- In the Restore Configuration pane, select the configuration you want to revert to. For example, in the picture above, the configuration from 07/11/2017 is selected and highlighted.
- Compare the "Latest Running Configuration Verified by CDO" and the "Selected Configuration from <date>" to ensure you want to restore the configuration displayed in the Selected Configuration from <date> window.
- Click Restore, this stages the configuration in CDO. On the Devices & Services page, you see that the configuration status of the device is "Not Synced."
- Click Write Changes... in the right-hand pane to write the changes and sync the ASA.
How do I recover changes I lost but wanted to keep?
- Select the ASA on the Devices & Services page.
- Click Change Log in the right pane.
- Review the changes in the change log. You may be able to reconstruct your lost configurations from those records.
