A Command Line Interface is a text-oriented user interface in contrast to a Graphical User Interface (GUI). The configuration and control of functions can be performed in both ways as well as by uploading a file for all current router products of INSYS icom *). The CLI can be accessed from the local network or remote using Telnet or encrypted via SSH and is protected against unauthorised access by user name and password (alternatively using a Radius server).
The direct access speeds up automated configuration processes significantly: If users want to configure several routers, this can be done much easier and faster automated using the Command Line Interface (CLI) compared to a manual configuration using the web interface. Alternatives are the uploading an ASCII file or using the auto update function of the devices.
CLI allows an automated, regular check for detecting unauthorised configuration changes or manipulations in case of increased IT security requirements, like in critical infrastructures for example.
*) CLI starting with Firmware 2.12.0
