Is it possible to undo last changes inMT router? in CISCO, you can print “no” before last script or, if necessary, reboot the router not saving the configuration. I think this is practical, as when someone makes a mistake thus resulting traffic stopping one can recover his mistake using these features.
Do we have similar recovery options in MT750
