When an admin>reboot command is issued, routers with redundant CSMs are rebooted. Changes are lost unless the configuration is saved. Use the admin>save file-url command to save the current configuration. If no command line options are specified, the user is prompted to confirm the reboot operation.
Use the following CLI syntax to reboot:
