The upgrade rollback command enables the version rollback function and sets a timeout period for version rollback.
The undo upgrade rollback command disables the version rollback function during version upgrade.
By default, the version rollback function is disabled.
Usage Scenario
If you need to cancel the version upgrade being performed for some reason (for example, a new startup file was damaged), you can run the upgrade rollback command to perform version rollback to restore the version being upgraded to the original version.
After the version rollback function is enabled and the system package is restarted, the system will perform a version rollback to roll back the system package and patch if no users successfully log in to the device in a specified period of time.
If the version rollback function is disabled, the system will not perform version rollback whether any users successfully log in to the device in a specified period of time.
By default, the version rollback function is disabled. After the version rollback function is performed, the system restores to the default setting.
Configuration Impact
After the command is run, the rollback timer of the current system will be reset.
Precautions
If users successfully log in to the device, the system automatically cancels the timeout period for version rollback.
The items that can be rolled back include system software and patch files.
