Step 2: Up and Running

Now that the ACX7100-32C 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 ACX7100-32C using the CLI. You can also onboard and manage the ACX7100-32C by using Paragon Automation. To onboard this device using Paragon Automation, see Onboard Cloud-Ready Devices with Paragon Automation.

Plug and Play

The ACX7100-32C 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 ACX7100-32C 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 ACX7100-32C to a laptop or desktop PC using the RJ-45 cable and RJ-45 to DB-9 adapter (not provided). 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.

  4. Start the CLI.

  5. Enter configuration mode.

  6. Stop the chassis auto-upgrade process.

  7. Stop zero-touch provisioning (ZTP).

    Note:

    ZTP is enabled on the ACX7100-32C 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.

  9. Commit the configuration, and wait for the ZTP process to stop.

    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 (“ ”).

  11. Configure the default gateway.

  12. Configure the IP address and prefix length for the management interface on the router. On the ACX7100-32C, the management (MGMT) port is the upper RJ-45 port on the right side of the port panel.

  13. (Optional) Configure specific static routes to remote prefixes if you do not want the remote prefixes to use the default route.

  14. Enable Telnet service, if required.

    Note:

    When Telnet is enabled, you cannot log in to the ACX7100-32C through Telnet using root credentials. Root login is allowed only for SSH access.

  15. Enable SSH service.

  16. To allow users to log in to the router as root through SSH, include the root-login statement.

    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.
