Configuration Rollback Confirmed Change
The Configuration Rollback Confirmed Change feature allows configuration changes to be performed with an optional requirement that they be confirmed. If this confirmation is not received, the configuration is returned to the state prior to the changes being applied. The mechanism provides a safeguard against inadvertent loss of connectivity between a network device and the user or management application due to configuration changes.

Information About Configuration Rollback Confirmed Change
Configuration Rollback Confirmed Change Operation
The Configuration Rollback Confirmed Change feature enables an added criterion of a confirmation to configuration changes. This functionality enables a rollback to occur if a confirmation of the requested changes is not received in a configured time frame. Command failures can also be configured to trigger a configuration rollback.
The following steps outline how this process is achieved:
How to Configure Configuration Rollback Confirmed Change
Performing a Configuration Replace or Configuration Rollback Operation with Confirmation
Perform this task to replace the current running configuration file with a saved Cisco configuration file.
Note | You must configure a configuration archive before performing this procedure. For detailed steps, see the “Configuring the Characteristics of the Configuration Archive” module in the Managing Configuration Files Configuration Guide. The following procedure details how to return to that archived configuration in the event of a problem with the current running configuration. |

DETAILED STEPS
Configuration Examples for Configuration Rollback Confirmed Change
Example: Performing a Configuration Replace Operation with the configure confirm Command
The following example shows the use of the configure replace command with the time minutes keyword and argument. You must enter the configure confirm command within the specified time limit to confirm replacement of the current running configuration file. If the configure confirm command is not entered within the specified time limit, the configuration replace operation is automatically reversed (in other words, the current running configuration file is restored to the configuration state that existed prior to entering the configure replace command).
Device# configure replace nvram:startup-config time 120 This will apply all necessary additions and deletions to replace the current running configuration with the contents of the specified configuration file, which is assumed to be a complete configuration, not a partial configuration. Enter Y if you are sure you want to proceed. ? [no]: Y Total number of passes: 1 Rollback Done Device# configure confirm
The following example shows the use of the configure revert command with the timer keyword. You must enter the configure revert command to cancel the timed rollback and trigger the rollback immediately, or to reset parameters for the timed rollback.
Device# configure revert timer 100
