Juniper: Basic CLI

Basic Connection and Configuration with the CLI

For CLI access, you connect from your management PC or laptop to the Services Router through the console port. (For information about the CLI, see JUNOS CLI Basics.) Step 1. Connecting, Logging In, and Starting the CLI

You are prompted for a username and password. The default username is root. Because no password is initially required, press Enter at the password prompt for a first-time login.

To access a Services Router with the JUNOS CLI:

   Turn off power to the management PC or laptop.
   Connect one end of the console cable to the serial port adapter, plug the adapter into a serial port on the PC or laptop, and plug the other end of the cable into the console port on the Services Router.
   Turn on power to the PC or laptop.
   On the PC or laptop, start the terminal emulation program (such as Microsoft Windows HyperTerminal), select the COM port, and configure the following port settings: 9600 (bits per second), 8 (data bits), none (parity), 1 (stop bits), and none (flow control).
   Press the POWER button on the router, and verify that the POWER LED turns green.
   Wait for the system to boot, and when presented with a login prompt, log in as root, and press Enter at the Password prompt.

   When you have been authenticated through the CLI, you enter the UNIX shell:

   routername (ttyd0)

   login: root

   Password:
   JUNOS 8.0R1 2006-07-01 01:59:49 UTC
   root@%

   At the % prompt, type the cli command and press Enter. The prompt changes to an angle bracket (>) when you enter CLI operational mode.
   root@% cli root

   root>

For complete instructions, see the Getting Started Guide for your router. Step 2. Updating the JUNOS Software with the CLI

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. You can use the CLI, but we recommend the J-Web interface for the download.

To update the JUNOS software with the CLI:

   Go to https://www.juniper.net/support, and follow the links to download the JUNOS software for J-series routers to an FTP server.
   Download the JUNOS software to the router with the CLI or J-Web interface:
       root> request system software add validate unlink reboot source

For complete instructions, see the J-series Services Router Administration Guide. Step 3. Adding Licenses with the CLI

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 from the CLI.

To add a license key and enable a license:

   Follow the instructions in your license envelope to generate the license key from the Web site.
   Copy the license key onto the router with the CLI:
       Type the following command, and press Enter:
           root> request system license add terminal
       When prompted, copy and paste the license key from the Web site at the command line, separating multiple license keys with a blank line.
       To exit license key entry, press Ctrl+D.

For complete instructions, see the Getting Started Guide for your router. Step 4. Configuring Basic Settings with the CLI

In CLI configuration mode, you use the set command to enable features, and the delete command to disable them. The commands you enter do not update the active configuration on the router until you use the commit command.

To configure basic settings with the CLI:

   From the CLI, enter configuration mode:
       root> configure
       root#
   Set the IP addresses of the built-in Ethernet ports. For example:
       On a J2300 router:

           root# set interfaces fe-0/0/0 unit 0 family inet address 192.168.1.1/24
           root# set interfaces fe-0/0/1 unit 0 family inet address 192.168.2.1/24

       On a J4350 or J6350 router:

           root# set interfaces ge-0/0/0 unit 0 family inet address 192.168.1.1/24
           root# set interfaces ge-0/0/1 unit 0 family inet address 192.168.2.1/24
           root# set interfaces ge-0/0/2 unit 0 family inet address 192.168.3.1/24
           root# set interfaces ge-0/0/3 unit 0 family inet address 192.168.4.1/24

   The unit number is the logical interface number. IP addresses are configured on the logical interface. Setting the protocol family to inet specifies the routing table of IPv4 addresses.
   Set a default route (default gateway) for IPv4 packets. For example:
       root# set routing-options static route 192.168.1.254/24 next-hop 10.1.1.50
   Configure one or more static routes:
       root# set routing-options static route destination-prefix next-hop address
   Set the hostname. For example:
       root# set system host-name Chicago
   Save your configuration settings and activate them on the Services Router:
       root# commit

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