Upgrading Software on QFX3500 and QFX3600 Standalone Switches

To upgrade Junos OS, you need to install the appropriate upgrade package on the QFX Series. Upgrading involves these tasks:

  1. Downloading Software Files with a Browser
  2. Accessing Software Downloaded to a Remote Location
  3. Connecting to the Console Port
  4. Backing Up the Current Configuration Files
  5. Installing the Software Package

Downloading Software Files with a Browser

To download the software package from the Juniper Networks Support website, go to https://www.juniper.net/support/ .

Note: To access the download site, you must have a service contract with Juniper Networks and an access account. If you need help obtaining an account, complete the registration form at the Juniper Networks website
https://www.juniper.net/registration/Register.jsp .

  1. Using a Web browser, navigate to the https://www.juniper.net/support .
  2. Click Download Software.
  3. In the Switching box, click Junos OS Platforms.
  4. In the QFX Series section, click the name of the platform for which you want to download software.
  5. Click the Software tab and select the release number from the Release drop-down list.
  6. In the Install Package section of the Software tab, select the Install Package for the release.

    A login screen appears.

  7. Enter your name and password and press Enter.
  8. Read the End User License Agreement, click the I agree radio button, and then click Proceed.
  9. Save the jinstall-qfx-<version>-domestic-signed.tgz file on your computer.
  10. Open or save the installation package either to the local system in the var/tmp directory or to a remote location. If you are saving the installation package to a remote system, make sure that you can access it using HTTP, TFTP, FTP, or scp.

Accessing Software Downloaded to a Remote Location

To access the installation package if you downloaded it to a remote location (for example, any system other than the switch):

  1. From the command line, make sure you are in the /var/tmp directory of the switch.
  2. Start the shell interface:
    user@switch> start shell
  3. Initiate an FTP, TFTP, or scp session.

    In this example, FTP is used.

    >ftp
  4. Use FTP to access the remote location where the installation package resides.
    ftp ftp://<hostname>/<pathname>/<package-name-m.mZx-distribution>.tgz.

    where <package-name-m.mZx-distribution>.tgz is jinstall-qfx-11.1R1.5-domestic-signed.tgz

  5. When prompted, enter your username and password.
  6. Use the get command to transfer the installation package from the remote location to your /var/tmp directory on your switch.
    get <package-name-m.mZx-distribution>.tgz
  7. Close the FTP session:
    bye

Connecting to the Console Port

We recommend that you connect to the console port while installing the installation package so you can respond to any required user input and detect any errors that may occur.

Backing Up the Current Configuration Files

Before you install the new installation package, we strongly recommend that you back up your current configuration files because the upgrade process removes all of the stored files on the switch.

To back up your current configuration files, enter the save command:

user@switch> save filename

Executing this command saves a copy of your configuration files to a remote location such as an external USB device.

Installing the Software Package

Note: Before you install the software, back up any critical files in /var/home. For more information regarding how to back up critical files, contact Customer Support at https://www.juniper.net/support.

Install the software in one of two ways:

If the installation package resides locally on the switch, execute the request system software add validate <pathname><source> reboot command.

For example:

user@switch> request system software add validate /var/tmp/jinstall-qfx-11.1R1.5-domestic-signed.tgz reboot

If the Install Package resides remotely, execute the request system software add validate <pathname><source> reboot command.

For example:

user@switch# request system software add validate ftp://ftpserver/directory/jinstall-qfx-11.1R1.5-domestic-signed.tgz reboot

After the reboot has finished, verify that the new version of software has been properly installed by executing the show version command.

user@switch> show version
