Removing a Persistent or Transient Configuration Change Using Commit Scripts
After a commit script changes the configuration, you can remove the change and return the configuration to its previous state.
For persistent changes only, you can undo the configuration change by issuing the delete, deactivate, or rollback configuration mode command and committing the configuration. For both persistent and transient changes, you must remove, delete, or deactivate the associated commit script, or else the commit script regenerates the change during a subsequent commit operation.
Deleting the file filename statement from the configuration effectively disables the functionality associated with the corresponding commit script. Deactivating the statement adds the inactive: tag to the statement, effectively commenting out the statement from the configuration. Statements marked as inactive do not take effect when you issue the commit command.
To reverse the effect of a commit script and prevent the script from running again:
For persistent changes only, delete or deactivate the statement that was added by the commit script:user@host# delete (statement | identifier)- OR –user@host# deactivate (statement | identifier)
Alternatively, you can roll back the configuration to a candidate that does not contain the statement.user@host# rollback number
Either delete or deactivate the commit script, or remove or comment out the section of code that generates the unwanted change. To delete or deactivate the script, issue one of the following commands.user@host# delete system scripts commit file filename- OR –user@host# deactivate system scripts commit file filename
Issue the commit command:user@host# commit
If you are deleting the reference to the script from the configuration, you can also remove the file from commit scripts storage directory (either
/var/db/scripts/commiton the hard disk or
/config/scripts/commiton the flash drive. To do this, exit configuration mode and issue the file delete operational mode command:user@host# exituser@host> file delete /var/db/scripts/commit/filename- OR –user@host> file delete /config/scripts/commit/filename
