Using the Default Button to Restore Factory Settings
When a fault, such as a device login failure, occurs due to incorrect configurations, hold down the Default button to enable the device to restart using the factory settings.
Method to restore factory settings: After the device is started, hold down the Default button for more than 3s. The device then uses the factory settings for a restart.
- After the factory settings are restored, the original configuration file still exists. Therefore, save your configurations before you hold down the Default button. You can run the startup saved-configuration command to change the startup configuration file; otherwise, the device uses the factory settings for the next startup.
- During your operations, do not power off the device.
