Installation & Operation Manual 33. Configuring Security Settings
33.18.7 CLI Interface Access Control
SSH and Telnet services on SC boards are used to access the Media Gateway
Command Line Interface (CLI). In the default configuration, these services are
accessible from any IP address and user authentication is performed via username
and password (see Section CLI User Administration) for details.
For enhanced security, you may restrict access to the SSH and Telnet services on SC
boards by specifying an explicit list of IP addresses that are allowed to access the CLI
interface.
To enable access control on the CLI interface:
1. Click
to access the Media Gateway status screen.
2. In the Navigation pane, select Security and then in the configuration pane, click
Security Settings; the Security Settings screen is displayed.
3. In the CLI Access Control section, configure the CLI Interface Access Control
parameters according to the table below.
