Overview of Services Routers

J-series Services Routers running the JUNOS Enhanced Services software provide stable, reliable, and efficient IP routing, WAN and LAN connectivity, and management services for small to medium-sized enterprise networks. These routers also provide network security features, including a stateful firewall with access control policies and screens to protect against attacks and intrusions, and IPSec VPNs. J-series Services Routers securely connect small, branch, and regional offices to a central site router across Internet service provider (ISP) networks.

J-series Services Routers run the JUNOS Enhanced Services software, which offers many advanced routing and security services. For more information about software features, see the Summary of JUNOS Enhanced Services Software Features.

You can use two user interfaces to monitor, configure, troubleshoot, and manage a Services Router:

• J-Web interface—A Web-based graphical interface that allows you to operate a router without commands. The J-Web interface provides access to all JUNOS functionality and features. Quick Configuration wizards simplify basic configuration and minimize the risk of operator error.
• JUNOS command-line interface—A 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.

For an introduction to the J-Web and CLI interfaces, see Services Router User Interface Overview. For more information, see the J-Web Interface User Guide and the JUNOS CLI User Guide
