Description
Use the reboot command to have the router reboot.
Executing this command is equal to powering up the router after a power-down, except
that you do not have to go to the site where the router is located.
Executing this command may halt network operation transiently; use it with caution. In
addition, save the configuration file before rebooting the router, because the
configurations you just made cannot survive a reboot.
