Configuring scheduled tasks
A scheduled task defines a command or a group of commands and when such commands are to be
executed. It allows a device to execute specified commands at a time when no person is available to
maintain the device.
With a scheduled task configured, the device checks the configured task list every minute. If the device
detects that the time to execute a command is reached, it automatically executes the command.
There are two approaches to configure a scheduled task. The following table compares the two approaches.

The system does not check whether entered view and command arguments are correct. You must ensure their
correctness. Otherwise, the commands cannot be executed.
The system does not require your confirmation when it is executing a scheduled task. If there is information
for you to confirm, the system automatically enters Y or Yes. If characters are required, the system
automatically enters a default character string, or enters an empty character string when there is no default
character string.
Execution of any command that changes the user interface (such as telnet, ftp, or ssh2), the view (such as
system-view or quit), or the user status (such as super) in a scheduled task does not change, the configuration
interface, view, and current user status.
When the specified time is reached, the system executes the specified command in the background without
displaying any prompt information except system information such as log, trap and debugging information.
