Configuring a QFX3600 Device as a Standalone Switch


If you are using the QFX3600 device as a standalone switch, you must perform the initial configuration of the QFX3600 device through the console port using the command-line interface (CLI). If you are using the QFX3600 device as a Node device in a QFabric system, you instead perform the initial setup of a QFabric system on a QFX3100 Director device (see Performing the QFabric System Initial Setup on a QFX3100 Director Group).

Before you begin connecting and configuring a QFX3600 device, 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

To connect and configure the device from the console:

  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 front panel of the device.
  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.
    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 device. 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 device management interface.
    root@# set interfaces me0 unit 0 family inet address address/prefix-length


    Configuring the two management Ethernet interfaces within the same subnet is not supported.


    The management ports are on the front panel of the QFX3600 device. They are labeled C0 and C1 on the front panel. In the CLI they are referred to as me0 and me1.

  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 telnet service.
    root@# set system services telnet


    When Telnet is enabled, you cannot log in to a QFX3600 device through Telnet using root credentials. Root login is allowed only for SSH access.

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