J2300, J4300, and J6300 Services Routers

J-series Services Routers provide stable, reliable, efficient IP routing, WAN and LAN connectivity, and management services for small to medium-sized enterprise networks. Services Routers typically connect small, branch, or regional offices to a central site router, and link Internet service provider (ISP) networks.

All J-series Services Routers run the JUNOS Internet software, which offers many advanced routing and security services. For more information about software features, see J-series Software Features and Licenses. A single, common JUNOS code base simplifies deployment, patches, and software upgrades.

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

• J-Web Web–based interface—Allows you to manage your Services Router without using the command-line interface (CLI). The J-Web interface provides access to all JUNOS functionality and features. The J-Web interface also provides Quick Configuration wizards to simplify operations and minimize the risk of operator error.
• JUNOS command–line interface—The JUNOS CLI is a Juniper Networks command shell that runs on top of a UNIX-based operating system kernel. The CLI is a straightforward command interface. You type commands on a single line, and the commands 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 additional information about CLI commands, see the JUNOS CLI User Guide.
