Performing the QFabric System Initial Setup on a QFX3100 Director Group

You must perform the initial setup of the QFX3100 Director group through the console port. (Before configuring the QFX3100 Director group, see Installing and Connecting a QFX3100 Director Device.)

Before you begin connecting and configuring a QFX3100 Director group, set the following parameter values on the console server or PC:

  • Baud Rate—9600

  • Flow Control—None

  • Data—8

  • Parity—None

  • Stop Bits—1

  • DCD State—Disregard

Note:

When you use the SecureCRT client to connect to a Director device for the initial setup of a QFabric system, the backspace key does not work. As a workaround, use the Shift+Delete key combination in SecureCRT as a backspace key equivalent or use a different UNIX client to support the backspace key natively.

The initial setup requires that you specify certain values for your QFabric system. These include:

  • Software serial number for your QFabric system (found in the e-mail containing the software serial number that you received from Juniper Networks when you purchased your QFabric system)

  • IP addresses and a default gateway IP address for your QFabric system default partition

  • IP addresses for your Director group device management ports

  • Range of reserved MAC addresses for your QFabric system (see Generating the MAC Address Range for a QFabric System or Activate Your QFabric System for this information)

  • Root password for your Director group

  • Root password for the QFabric system components such as the Node devices, Interconnect devices, and infrastructure

Performing an Initial Setup

The initial setup can be performed either manually or by using a previously saved backup configuration.

To connect and configure the QFX3100 Director group manually from the console:

  1. Connect the console port of one of the Director devices to a laptop or PC using an RJ-45 to DB-9 rollover cable. An RJ-45 to DB-9 rollover cable is supplied with each QFX3100 Director device. The console (CONSOLE) port is located on the front panel of the device.
  2. Log in as root. If the software booted before you connected to the console port, you might need to press the Enter key for the prompt to appear.
    Note:

    The prompt is either dg0 login or dg1 login depending on the Director device to which you connected your cable.

  3. For manual configuration or for initial installation, enter no when prompted to specify the backup file. The current Director device configuration is displayed.
  4. Enter the IP addresses and prefixes for both Director devices.
    Note:

    The Director group devices and QFabric system default partition IP addresses must be on the same subnet as your management network.

  5. Enter the gateway IP address for the Director group.
  6. Enter the default partition IP address. (You will use this address to log in to the QFabric system on subsequent connections.)
  7. (Optional) Enter the IPv6 addresses for both Director devices and the gateway IPv6 address for the Director group.
  8. Enter the MAC address information.
    Note:

    The minimum number of MAC addresses accepted is 4000.

  9. Enter the QFabric system software serial number.
  10. Create the Director device root password.
  11. Create a password for the QFabric system components.
    Note:

    If you need to change the component password after the QFabric system is operational, issue the device-authentication statement at the [edit system] hierarchy level in the QFabric default partition CLI.

    CAUTION:

    Carefully save your passwords for future reference, because some cannot be recovered on a QFabric system.

  12. Enter the QFabric system platform type.
  13. Confirm the initial configuration. Ensure that the information is accurate before proceeding.
    Note:

    Only addresses of the IP version(s) you entered will appear in the configuration.

  14. Confirm the initial setup.
    CAUTION:

    Resetting this initial configuration requires assistance from Juniper Networks customer support or Performing a QFabric System Recovery Installation on the Director Group. As a result, make sure you are certain the values you entered are correct before you enter yes.

  15. The director device displays the configuration.

Restoring a Backup Configuration

Before you restore a backup configuration for the Director group:

To connect and configure the Director group with a backup configuration:

  1. Log in as root. If the software booted before you connected to the console port, you might need to press the Enter key for the prompt to appear.
    Note:

    The prompt is either dg0 login or dg1 login depending on the Director device to which you connected your cable.

  2. To use a previously saved backup configuration, enter yes when prompted to specify the backup file and then enter the path and filename of the backup configuration.
  3. Confirm the restoration of the configuration from the backup. Ensure that the information is accurate before proceeding.
  4. Confirm the backup restoration.

    The Director device displays the configuration.
