Step 2. Updating the JUNOS Software with the CLI
+
Model: j2300
 +
JUNOS Software Release [8.0-20060607.0] (Export edition)
  
−
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 access configuration mode, enter the configure command. The prompt changes to a pound sign (#).
  
−
To update the JUNOS software with the CLI:
+
root> configure
  
−
    Go to https://www.juniper.net/support, and follow the links to download the JUNOS software for J-series routers to an FTP server.
+
root#
−
    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.
+
To activate changes to the configuration, enter the commit command.
−
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.
+
root> commit
  
−
To add a license key and enable a license:
+
root#
  
−
    Follow the instructions in your license envelope to generate the license key from the Web site.
+
To exit configuration mode, enter the exit command. Use the exit command again to exit the CLI completely.
−
    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.
+
root# exit
−
Step 4. Configuring Basic Settings with the CLI
+
root> exit
−
 
+
root@%
−
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.
