Step 2: Up and Running

Now that the QFX10016 is powered on, let’s do some initial configuration to get it up and running on the network.

Connect to the Network

You can configure and manage the chassis by using a dedicated console. Every control board has a console port with an RJ-45 connector. Use the console port to connect the device to the management console or to a console server. The console port accepts a cable with an RJ-45 connector.

Ensure that you have an Ethernet cable with an RJ-45 connector available. An RJ-45 cable and an RJ-45 to DB-9 serial port adapter are supplied with the device.


If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC directly to the device, use a combination of the RJ-45 to DB-9 female adapter supplied with the device and a USB to DB-9 male adapter. You must provide the USB to DB-9 male adapter.

To connect the chassis to the network using the console port:

  1. Connect one end of the Ethernet cable into the console port labeled CON on the control board.
  2. Connect the other end of the Ethernet cable into the console server.

Perform Initial Configuration

You must perform the initial configuration of a QFX10016 switch through the console port using the CLI.

Before you begin connecting and configuring the switch, set the following parameter values on the console server or PC, verify that the following default serial port settings are configured on your laptop or desktop PC:

  • Baud Rate—9600

  • Flow Control—None

  • Data—8

  • Parity—None

  • Stop Bits—1

  • DCD State—Disregard

  1. Connect the console port to a laptop or PC using the supplied RJ-45 cable and RJ-45 to DB-9 adapter. The console (CON) port is located on the port panel of the switch.
  2. 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.
  3. Start the CLI.
  4. Enter configuration mode.
  5. Add a password to the root administration user account.
  6. (Optional) Configure the name of the switch. If the name includes spaces, enclose the name in quotation marks (“ ”).
  7. Configure the default gateway.
  8. Configure the IP address and prefix length for the switch management interface.

    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 (MGMT for RJ-45 connections) and em1 (also labeled MGMT for fiber connections) are found on each of the control boards of the QFX10016.

  9. (Optional) Configure the static routes to remote prefixes with access to the management port.
  10. Enable Telnet service.

    When Telnet is enabled, you cannot log in to a QFX10016 through Telnet using root credentials. Root login is allowed only for SSH access.

  11. Commit the configuration to activate it on the switch.
