Usage Guidelines

If the matched upper-view command is run, when you run an undo command that is not registered in the current view, a device searches for the undo in the upper view. If the device finds the same undo command, it executes this command in the upper view. If the device does not find the same undo command in the upper view, it continues to search for this command in more upper views till the system view.

Running this command brings security risks. For example, if you run the undo ftp server command in the interface view, while this command is not registered in the interface view, the device automatically searches for it in the upper view, that is, the system view, and disables the FTP function.

The matched upper-view command is valid only for current login users who run this command.
