Perform the Initial Configuration for the PTX10016 Router

You must perform the initial configuration of the PTX10016 router through the console port using the CLI or through zero-touch provisioning (ZTP). To use ZTP to provision the device, you must have access to a Dynamic Host Control Protocol (DHCP) server, and a FTP (anonymous FTP), HTTP, or Trivial File Transfer Protocol (TFTP) server on which the software image and configuration files are stored. For more information about using ZTP for provisioning the device, see Understanding Zero Touch Provisioning in the Installation and Upgrade Guide.

These procedures walk you through the configuration of the PTX10016 using the console CON|CONSOLE port on the RCB. For directions on connecting into a console server or a management server, see Connect the PTX10016 Router to a Management Console.

Before You Begin

  1. Set the following serial port settings for your laptop or desktop PC:
    • Baud Rate—9600

    • Flow Control—None

    • Data—8

    • Parity—None

    • Stop Bits—1

    • DCD State—Disregard

  2. Gather the information you will need to configure the PTX10016:
    • The password you’ll set for the root user

    • The name on the system that the PTX10016 will be known as (host name)

    • The IP address and prefix of the default gateway router

    • The IP address and prefix length information for the Ethernet interface

    • The IP address and prefix length of remote prefixes

Enter the Configuration Mode

  1. Check that the PTX10016 has power.
  2. Connect the console port on the router to a serial port on your laptop or desktop PC by using the supplied RJ-45 cable and RJ-45 to DB-9 adapter. The console port (labeled CONSOLE or CON) is located on the RCB installed in the router. If your laptop or desktop PC doesn't have a serial port, use a serial-to-USB adapter (not provided).
  3. At the login prompt, type root. You don't need to enter a password. If the software booted before you connected 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.

Establish a Root Password and Optional Host Name

  1. Add a password to the root administration user account.
  2. (Optional) Configure the name of the router. If the name includes spaces, enclose the name in quotation marks (“ ”).

Configure the Default Gateway and Ethernet Interface

  1. Configure the default gateway.
    • If Junos OS is installed in your router:

    • If Junos OS Evolved is installed in your router:

  2. Configure the IP address and prefix length for the router management interface.
    • If Junos OS is installed in your router:

    • If Junos OS Evolved is installed in your router:


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


    The management ports (labeled MGMT) em0 or re0:mgmt-0 (for RJ-45 connections) and em1 (for fiber connections), are on the RCB on the PTX10016 router.

Configure Optional Routes, Services, and Commit the Configuration

  1. (Optional) Configure the static routes to remote prefixes with access to the management port.
  2. Enable services such as SSH and Telnet.

    You cannot log in to the router as the root user through Telnet. Root login is allowed only through SSH.

  3. Commit the configuration to activate it on the router.
