Revision 1

J-series Services Routers provide IP routing, WAN and LAN connectivity, and

management services. Available in several models, Services Routers typically

connect small, branch, or regional offices to a central site, and link Internet service

provider (ISP) networks.

Follow these instructions to initially set up a J-series Services Router. You need no

previous JUNOS Internet software experience, but must have managed a network

and configured other routers. For more information, see the J-series documentation

at http://www.juniper.net/techpubs/.

J-series Services Router Quick Start

2!What You Need to Know

What You Need to Know

Management IP

Address

When you first connect a management PC or laptop to a built-in Ethernet port on a

Services Router, the router acts as a DHCP client and attempts to perform an

autoinstallation. If it does not find a DHCP server, the router assigns

192.168.1.1/24 as the IP address for port 0. (If you are connected to port 1,

192.168.2.1/24 is assigned as the IP address. On the J4350 and J6350 routers, port

2 and port 3 are assigned 192.168.3.1/24 and 192.168.4.1/24, respectively.)

Because this address is not part of any explicit configuration, it is removed when

you change the configuration in any way. You must configure an IP address for this

LAN port when you commit your initial configuration. (See “4. Configuring Basic

Settings with J-Web Quick Configuration” on page 8 or “4. Configuring Basic

Settings with the CLI” on page 12.)

J-Web Access The Web interface to the router—called the J-Web interface—is enabled by default.

To configure the router with the Web interface, you attach a PC or laptop to a

built-in Ethernet port. The examples in this document use the first built-in Ethernet:

!On J2300, J4300, and J6300 routers, the first built-in Ethernet port is Fast

Ethernet PORT 0 (internally named fe-0/0/0).

!On J4350 and J6350 routers, the first built-in Ethernet port is Gigabit Ethernet

port 0/0 (internally named ge-0/0/0).

See “1. Connecting, Logging In, and Starting the J-Web Interface” on page 7.

CLI Console Access Services Routers are shipped with a console cable and adapter. To configure a

Services Router through the console port with the JUNOS command-line interface

(CLI), you use a terminal emulation program such as Microsoft Windows

HyperTermimal. (See “1. Connecting, Logging In, and Starting the CLI” on page 10.)

Required Licenses To use the following features on a Services Router, you must purchase a license.

(See “3. Adding Licenses with the CLI” on page 11 or “4. Configuring Basic Settings

with J-Web Quick Configuration” on page 8.)

!Advanced Border Gateway Protocol (BGP) support for route reflectors

!Data link switching (DLSw)

!J-Flow traffic analysis

Slot Numbers J2300 routers have built-in WAN ports. Other models have slots 1 through 6 for

replaceable Physical Interface Modules (PIMs). On J4300 and J6300 routers, PIM

slots are numbered from left to right, bottom to top. On J4350 and J6350 routers,

PIM slots are numbered from top to bottom, left to right.

Interfaces and Ports Interfaces are named by type, slot number, module number (always 0), and port

number. Port numbering starts with 0. For example:

!On J2300, J4300, and J6300 routers, built-in Fast Ethernet LAN PORT 0 and

PORT 1, which are in slot 0, are named fe-0/0/0 and fe-0/0/1.

Before You Begin !3

J-series Services Router Quick Start

!On J4350 and J6350 routers, the built-in Gigabit Ethernet LAN ports 0/0

through 0/3, which are in slot 0, are named ge-0/0/0, ge-0/0/1, ge-0/0/2, and

ge-0/0/3.

!On models with replaceable PIMs, the first port on a T1 PIM in slot 1 is named

t1-1/0/0.

Remote Access Although Telnet and SSH are both supported, they are disabled by default.

Basic Connection and Configuration with the J-Web Interface !7

J-series Services Router Quick Start

Basic Connection and Configuration with the J-Web Interface

For J-Web access, you connect from your management PC or laptop to the Services

Router through one of the built-in Ethernet interfaces. The examples in this

document use port 0. (For information about the J-Web interface, see “J-Web

Basics” on page 13.)

1. Connecting, Logging In, and Starting the J-Web Interface

When the Services Router is powered on for the first time, it looks for a DHCP

server, and if it does not find one, it assigns an IP address within the

192.168.1.0/24 subnetwork to any devices connected to it.

To connect to the J-Web interface through port 0/0 on the router:

1. On the management device, such as a PC or laptop, you use to access the J-Web

interface, verify that the address of the port that you connect to the router is set

to one of the following:

!An Ethernet address on the 192.168.1/24 subnetwork other than

192.168.1.1

!An Ethernet address from a DHCP server

2. Turn off the power to the management device.

3. Plug one end of the Ethernet cable into the Ethernet port on the management

device.

4. Connect the other end of the Ethernet cable to the built-in Ethernet port on the

router.

5. Power on the router by pressing the power button on the front panel.

6. Wait until the STATUS LED on the front panel turns solid green.

7. Turn on the power to the management device. The router assigns an IP address

to the management device within the 192.168.1/24 subnetwork if the device is

configured to use DHCP.

8. From the management device, open a Web browser and enter the IP address

192.168.1.1 in the address field. The Set Up Quick Configuration page appears.

9. Configure basic settings for your router as described in 4. Configuring Basic

Settings with J-Web Quick Configuration on page 8.

NOTE: You must manually configure the IP address for the management port you

are using before you save your initial configuration. When you save the

configuration for the first time, the DHCP lease is lost and you will lose the

connection to the router if you have not manually configured the IP address. If you

lose connection through the management interface, you must connect through the

console port.

3. Adding Licenses with the J-Web Interface

If you purchased one or more licenses, you received an envelope with instructions

for obtaining license keys from the Web. To enable each license on the router, you

must add the license key. You can add one or more license keys. To add a license

key and enable a license:

1. Follow the instructions in your license envelope to generate the license key

from the Web site.

2. Copy the license key onto the router with the J-Web interface:

a. Click Manage>Licenses.

b. Enter the license key in one of the following ways:

!In the License File URL box, type the URL for the license key Web site.

!Copy the license key text, and paste it into the License Key Text box,

separating multiple license keys with a blank line.

c. Click OK.

For complete instructions, see the Getting Started Guide for your router.

4. Configuring Basic Settings with J-Web Quick Configuration
