SRX320 Services Gateway CLI and J-Web Access
The SRX320 Services Gateway runs the Junos operating system (Junos OS). You can
use two user interfaces to monitor, configure, troubleshoot, and manage the services
gateway:
•J-Web interface—A Web-based graphical interface that allows you to operate the
services gateway without commands.
•Junos OS command-line interface (CLI)—Juniper Networks command shell that runs
on top of a UNIX-based operating system kernel. The CLI is a straightforward command
interface. On a single line, you type commands that are executed when you press the
Enter key. The CLI provides command help and command completion.
In addition, you can also use Junos Space Security Director to define and manage security
policies on the services gateway.
