About system shell menu

The system shell provides simple, menu-driven, text-prompt access to basic platform settings, including IP network settings, platform credentials, system time, and enabling/disabling SFTP/SSH and Telnet. Also, you can use it to perform a TCP/IP ping from the controller to another host controller.

Changes issued in the system shell become immediately effective, except for IP address settings (Update Network Settings). You must reboot the controller for any changed network settings to become effective.

If SSH is enabled in a controller, you can also access the controller’s system shell with a remote terminal session using SSH. Platform logon is still required (just as with a controller powered up in serial shell mode).

 
CAUTION: Be careful when changing items from the system shell, in particular platform account (logon credentials) and network settings. If you change platform logon credentials and then lose or forget them, you can restore the factory default platform credentials—however, you will need to make a serial shell connection, reboot the controller, and then be careful to press a key at the appropriate time during boot up sequence.
 

Following, is an example of the main controller system shell menu.
