Configuring the QFabric Switch 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

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

• Serial ID (found on your purchase order)
• IP addresses and a default gateway IP address for your QFabric switch default partition
• IP addresses for your Director group device management ports
• Range of reserved MAC addresses for your QFabric switch
• Root password for your Director group
• Root password for the QFabric switch components such as the Node devices, Interconnect devices, and infrastructure

Note: To request your MAC address block for your QFabric switch, visit the License Management System website. Navigate to the LMS Portal and enter your Juniper Networks user ID and password. On the Manage Product Licenses page, select QFX Series Product from the pull-down menu and click the Go button. On the Generate Licenses page, select QFX Series Product Fabric and click on the Continue button. On the next page, enter your software serial number, QFabric system identifier, and authorization code, then click the Download/E-mail MAC Address button. For more information about obtaining a QFabric switch MAC address block from the LMS portal, see https://www.juniper.net/us/en/local/pdf/lms/9060069-en.pdf

Initial Setup

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

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.
   dg0 login: root

   
   

   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.
   Initial Configuration

   
   

   Before you can access the QFabric switch, you must complete the initial setup of the Director group by using the steps that follow. If the initial setup procedure does not complete successfully, log out of the Director device and then log back in to restart this setup menu.

   
   

   Continue? [y/n]: yes

   
   

   You may enter the configuration manually or restore from a backup.

   
   

   Specify a backup file? [y/n]: no

   
   

   Existing local configuration:
4. Enter the IP addresses and prefixes for both the Director devices.

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

   Please enter the Director Group 0 IP address and prefix: ip address/prefix

   
   
   Please enter the Director Group 1 IP address and prefix: ip address/prefix
5. Enter the gateway IP address for the Director group.
   Please enter the Director Group gateway IP address: gateway ip address

   
   
6. Enter the default partition IP address. (You will use this address to log in to the QFabric on subsequent connections.)
   Please enter the QFabric default partition IP address: ip address

   
   
7. Enter the MAC address information.
   Please enter the starting MAC address: mac address

   
   
   Please enter the number of MAC addresses: number of mac addresses

   
   

   Note: The minimum number of MAC addresses accepted is 4000.

8. Enter the QFabric switch serial ID number.
   Please enter the QFabric serial ID: serial id
9. Create the Director device root password.
   Please enter a Director device root password: director-device-password

   
   

   Please re-enter the password: director-device password
10. Create a password for the QFabric switch components.
    Please enter a password for QFabric components (Node devices, Interconnect devices, and infrastructure): component-password

    
    

    Please re-enter the password: component-password

    
    

    Note: please record your passwords for recovery purposes.

    Caution: Carefully save your passwords for future reference, because they cannot be retrieved on a QFabric switch.

11. Confirm the initial configuration. Ensure that the information is accurate before proceeding.
