Step 2: Up and Running

 

Now that the ACX7100-48L 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 ACX7100-48L using the CLI.

Plug and Play

The ACX7100-48L 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 ACX7100-48L 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—Disregard

  2. Connect the console port on the ACX7100-48L to a laptop or desktop PC using the RJ-45 cable and RJ-45 to DB-9 adapter. The console (CON) port is the lower RJ-45 port on the right side of the port panel.Note

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

  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.

    re0 login: root
  4. Start the CLI.
    [vrf:none] root@re0:~# cli
  5. Enter configuration mode.
    root@re0> configure
  6. Stop the chassis auto-upgrade process.
    [edit]
    root@re0# delete chassis auto-image-upgrade
  7. Stop zero-touch provisioning (ZTP).
    [edit]
    root@re0# delete system commit factory-settings
    Note

    ZTP is enabled on the ACX7100-48L in the factory-default configuration. You must stop ZTP before you configure any settings. Until you assign a root password and make an initial commit, you might see ZTP-related messages on the console. You can safely ignore these messages while you configure the root password.

  8. Add a password for the root administration user account.
    [edit]
    root@re0# set system root-authentication plain-text-password
    New password: password
    Retype new password: password
  9. Commit the configuration, and wait for the ZTP process to stop.
    [edit]
    root@re0# commit

    A message appears on the console, confirming that the ZTP process has stopped.

  10. (Optional) Give the router a name. If the name includes spaces, enclose the name in quotation marks (“ ”).
    [edit]
    root@re0# set system host-name host-name
  11. Configure the default gateway.
    [edit]
    root@re0# set routing-options static route 0.0.0.0/0 next-hop destination-ip
  12. Configure the IP address and prefix length for the management port on the router.

    On the ACX7100-48L, the management (MGMT) port is the upper RJ-45 port on the right side of the port panel.

    [edit]
    root@re0# set interfaces re0:mgmt-0 unit 0 family inet address address/prefix-length
  13. (Optional) Configure specific static routes to remote prefixes if you do not want the remote prefixes to use the default route.
    [edit]
    root@re0# set routing-options static route address/prefix-length next-hop destination-ip
  14. Enable Telnet service, if required.
    [edit]
    root@re0# set system services telnet
    Note

    When Telnet is enabled, you cannot log in to the ACX7100-48L through Telnet using root credentials. Root login is allowed only for SSH access.

  15. Enable SSH service.
    [edit]
    root@re0# set system services ssh
  16. To allow users to log in to the router as root through SSH, include the root-login statement.
    [edit system services ssh]
    root@re0# root-login allow
    Note

    By default, users are not allowed to log in to the router as root through SSH.

  17. Commit the configuration.

    Your changes become the active configuration for the router.

    [edit]
    root@re0# commit
