Configuring a QFX5110

Before you begin connecting and configuring a QFX5110, 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

You must perform the initial configuration of the QFX5110 through the console port using the command-line interface (CLI).

To connect and configure the switch 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 management 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.
    CAUTION:

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

    Note:

    The management ports em0 (C0) and em1 (C1) are found on the FRU end of the QFX5110 switch.

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

    When Telnet is enabled, you cannot log in to a QFX5110 switch through Telnet using root credentials. Root login is allowed only for SSH access.

  11. Enable SSH service for root login.
  12. Commit the configuration to activate it on the switch.
