Tlhahisoleseding ka Femethari Reset
Factory Reset is a process of clearing the current running and start-up configuration information on a device, and resetting the device to an earlier, fully-functional state.
The factory reset process uses the factory-reset all command to take backup of existing configuration, and then reset the router to an earlier, fully functional state. The duration of the factory reset process is dependent on the storage size of the router. It can vary between 30 minutes on a C8500 consolidated platform, and up to 3 hours on a high availability setup.
