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.)

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

When the Services Router is powered on for the first time, it searches 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:
  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.

    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.

Step 2. Updating the Software with the J-Web Interface

After starting up the Services Router, you might want to download the latest version of the JUNOS software from the Juniper Networks Web site and load it onto the router. To update the JUNOS software:

  1. Go to https://www.juniper.net/support, and follow the links to download the JUNOS software for J-series routers to your PC or laptop.
  2. Log in to the J-Web interface.
  3. Click Manage>Software>Upload software package.
  4. Click Browse, locate the JUNOS software package file on your PC or laptop hard drive, and open the file.
  5. Select the check box next to Reboot If Required, and click Upload Package.

For complete instructions, see the J-series Services Router Administration Guide.

Step 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:
    1. Click Manage>Licenses.
    2. 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.
    3. Click OK.

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

Step 4. Configuring Basic Settings with J-Web Quick Configuration

When you click OK or Apply on J-Web Quick Configuration pages, the configuration is saved and activated automatically. To configure basic settings with the J-Web interface:

  1. If the Set Up Quick Configuration page is not displayed, select Configuration>Quick Configuration >Set Up.
  2. Enter information in the boxes on the Set Up Quick Configuration page as shown in Table 2, then click OK or Apply.

    Table 2: J-Web Set Up Quick Configuration

    Field

    Description

    Host Name (required)

    Hostname of the router—for example, Chicago.

    Domain Name

    Network or subnetwork that the router belongs to.

    Root Password (required)

    Root password that user “root” can use to log in to the router.

    Verify Root Password (required)

    Retyped password.

    Time Zone

    Time zone in which the router is located.

    NTP Servers

    NTP server to synchronize the system time.

    Current System Time

    Your current time and date.

    DNS Name Servers

    DNS server to resolve hostnames into addresses.

    Domain Search

    Name of each domain to include in a DNS search.

    Default Gateway

    Default route. The IP address of a default router that the Services Router can use to direct packets addressed to networks not explicitly listed in the routing table.

    Loopback Address

    Reserved IP address that is always available on the router. By default, this address is set to 127.0.0.1/32.

    fe-0/0/0 Address

    or

    ge-0/0/0 Address

    IP address and prefix length of built-in Ethernet port 0. The interface fe-0/0/0 or ge-0/0/0 is typically used as the management interface for accessing the router. The DHCP client sets this address to 192.168.1.1/24 if no DHCP server is found.

    You must enter the fe-0/0/0 or ge-0/0/0 address on the Quick Configuration Set Up page before you click Apply or OK. If you do not manually configure this address, the DHCP lease is lost and you will lose your connection to the J-Web interface when you click Apply or OK.

    Allow Telnet Access

    Enables remote access to the router with Telnet.

    Allow JUNOScript over Clear-Text Access

    Allows JUNOScript to send unencrypted text to the router over a TCP connection.

    Allow SSH Access

    Enables remote SSH access to the router.
  3. To configure additional interfaces:
    1. Under Quick Configuration, click Interfaces, and then click the interface you want to configure.
    2. On the Interfaces page, click Add to add a logical interface.

      IP addresses are configured on the logical interface.

    3. In the two boxes provided, type the IP address (for example, 192.168.1.4) and the number of bits in the subnet mask (for example, 24), click Add, and then click OK or Apply.

    To edit an existing interface, you click the logical interface.

  4. To enable routing protocols, under Quick Configuration click Routing.

For complete instructions, see the J-series Services Router Basic LAN and WAN Access Configuration Guide.
