Performing the Initial Software Configuration for the PTX10001


You must perform the initial configuration of the PTX10001 through the console port by using the Junos OS command-line interface (CLI).

Before you begin connecting and configuring a PTX10001, set the following parameter values on the management console or console server:

  • Baud Rate—9600

  • Flow Control—None

  • Data—8

  • Parity—None

  • Stop Bits—1

  • DCD State—Disregard

To connect and configure the PTX10001 from the console:

  1. Connect the console port to a laptop or PC by using the supplied RJ-45 cable and RJ-45 to DB-9 adapter. The console port (labeled CON) is located on the management panel of the PTX10001 (see Connecting the PTX10001 to a Management Console for more information).
  2. Log in as root. There is no password. If the software boots before you connected to the console port, you might need to press the Enter key for the prompt to appear.
    login: root

  3. Start the CLI.
    root@% cli

  4. Enter configuration mode.
    root> configure

  5. Add a password to the root administration user account.
    root@# set system root-authentication plain-text-password
    New password: password
    Retype new password: password

  6. (Optional) Configure the name of the PTX10001. If the name includes spaces, enclose the name in quotation marks (“ ”).
    root@# set system host-name host-name

  7. Configure the default gateway.
    root@# set routing-options static route default next-hop address

  8. Configure the IP address and prefix length for the management interface.
    root@# set interfaces em0 unit 0 family inet address address/prefix-length


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


    The management port em0 is on the port panel and the management port em2 is on the FRU end of the PTX10001 router.

  9. (Optional) Configure the static routes to remote prefixes with access to the management port.
    root@# set routing-options static route remote-prefix next-hop destination-ip retain no-readvertise

  10. Enable the Telnet service.
    root@# set system services telnet


    When Telnet is enabled, you cannot log in to a PTX10001 through Telnet by using root credentials. Root login is allowed only for SSH access.

  11. Enable SSH service for root login.
    root@# set system services SSH

  12. Commit the configuration to activate it on the device.
    root@# commit
