Rebooting the device
To reboot the device, use one of the following methods:
•
Reboot the device at the CLI. You can remotely reboot the device in either of the following ways:
Reboot the device immediately by using the
reboot
command.
Schedule a reboot to occur at a specific time or date or after a delay by using the
schedule reboot
command.
•
Power off and power on the device. This method cuts off the power of the device forcibly, which
might cause data loss. It is the least-preferred method.
