Perform the Initial Configuration for the PTX10008 Router

You must perform the initial configuration of the PTX10008 through the console port using the CLI or through Zero Touch Provisioning (ZTP). In order to use ZTP to provision the device, you must have access to a Dynamic Host Control Protocol (DHCP) server, and a File Transfer Protocol (anonymous FTP), Hypertext Transfer Protocol (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 Software Installation and Upgrade Guide.

These procedures step you through the configuration of the PTX10008 using the console CON|CONSOLE port on the Routing and Control Board (RCB). For directions on connecting into a console server or a management server, see Connect a PTX10008 Router to a Management Console.

Before You Start

  1. Set the following values on the console server or PC:
    • Baud Rate—9600

    • Flow Control—None

    • Data—8

    • Parity—None

    • Stop Bits—1

    • DCD State—Disregard

  2. Gather the information you will need for configuring the PTX10008:
    • The password you’ll set for the root user

    • The name on the system that the PTX10008 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 Configuration Mode

  1. Check that the PTX10008 has power.
  2. Connect the console port to a laptop or PC using an RJ-45 cable and RJ-45 to DB-9 adapter. The console (CON) port is located on the port panel of the router.
  3. Log in as root. There is no 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.
    • For standard Junos OS systems:

    • For Junos OS Evolved system:

  2. Configure the IP address and prefix length for the router management interface.
    • For standard Junos OS systems:

    • For Junos OS Evolved systems:


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


    The management ports, em0 or re0:mgmt-0 (MGMT for RJ-45 connections) and em1 (also labeled MGMT for fiber connections), are found on the front of the RCBs of the PTX10008 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 will not be able to 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.
