Step 2: Up and Running

 

Now that the ACX7509 is powered on, let’s do some initial configuration to get it up and running on the network. It’s simple to configure and manage the ACX7509 using the CLI. You can also onboard and manage the ACX7509 by using Paragon Automation. To onboard this device using Paragon Automation, see Onboard Cloud-Ready Devices with Paragon Automation.

Plug and Play

The ACX7509 router ships with factory-default settings that enable plug-and-play operation. These settings load as soon as you power on the router.

Customize the Basic Configuration

You can easily customize the factory-default configuration with just a few commands. Initially, you’ll need to make changes through the console port. After you configure the management port, you can access the ACX7509 using SSH and make additional configuration changes. You can always revert to the factory-default configuration whenever you want.

Have the following information ready before you begin customizing the router:

  • Hostname

  • Root authentication password

  • Management port IP address

  • Default gateway IP address

  • IP address and prefix length of remote prefixes

  • (Optional) SNMP read community, location, and contact information

  1. Verify that the following default serial port settings are configured on your laptop or desktop PC:

    • Baud Rate—9600

    • Flow Control—None

    • Data—8

    • Parity—None

    • Stop Bits—1

    • DCD State—Supported

      Note

      When console is supported with DCD, TOD functionality cannot be supported. Console without DCD and TOD can be simultaneously supported when you use a Y cable.

  2. Connect the console (CON) port on the ACX7509 to a laptop or PC using the RJ-45 cable and RJ-45 to DB-9 adapter. You'll find the console (CON) port on the router's Routing Control Board (RCB).Note

    If your laptop or desktop PC doesn't have a serial port, use a serial-to-USB adapter (not provided).

    Note

    We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable as part of the device package. If you require a console cable, you can order it separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).

  3. At the Junos OS login prompt, type root to log in.

    You don't need to enter a password. If the software boots before you connect your laptop or desktop PC to the console port, you might need to press the Enter key for the prompt to appear.

    login: root
  4. Start the CLI.
    root@% cli
  5. Enter configuration mode.
    root> configure
  6. Add a password to the root administration user account.
    [edit]
    root@# set system root-authentication plain-text-password
    New password: password
    Retype new password: password
  7. (Optional) Configure the name of the router. If the name includes spaces, enclose the name in quotation marks (“ ”).
    [edit]
    root@# set system host-name host-name


  8. Configure the default gateway.
    [edit]
    root@# set system management-instance
    root@# set routing-instances mgmt_junos routing-options static route prefix/prefix-length next-hop default-gateway-ip-address


  9. Configure the IP address and prefix length for the router management interface.
    [edit]
    root@# set interfaces re0:mgmt-0 unit 0 family inet address ip-address/prefix-length
    Caution

    Although the CLI permits you to configure two management Ethernet interfaces within the same subnet, only one interface is usable and supported.

    Note

    You’ll find the management ports, em0 or re0:mgmt-0 (MGMT for RJ-45 connections) and em1 (also labeled MGMT for fiber connections), on the front of the router's RCBs.

  10. (Optional) Configure the static routes to remote prefixes with access to the management port.
    [edit]
    root@# set routing-options static route remote-prefix next-hop destination-ip retain no-readvertise
  11. Enable services such as SSH and Telnet.Note

    You won’t be able to log in to the router as the root user through Telnet. You can only log in as root through SSH.

    [edit]
    root@# set system services telnet
  12. Commit the configuration to activate it on the router.
    [edit]
    root@# commit
