This section describes configuration options to enhance the level of
protection of your system. For more details, please see “Command
Line Interface” in Chapter 5.
1. If you have not already done so, change the admin password by
typing the config cli username command.
2. Set security to closed or custom mode typing the config sys
security mode command. Closed
mode restricts administration to the serial port. By default, the
custom mode enables both SSH and the serial port. You can
view the current settings of your system typing the
