### Command line interface <a href="#securitysettings-commandlineinterface" id="securitysettings-commandlineinterface"></a>

Allows to enable / disable remote device control by the command line using Telnet and SSH protocols.

SSH (Secure Shell) protocol provides secure remote control to network devices. Its functionality is similar to the Telnet protocol, but, unlike Telnet, SSH encodes all protocol messages, including transmitted passwords. By default, only access via Telnet is enabled.
