Software Upgrade Procedure Overview

You can upgrade FastIron software in several ways: through a manual step-by-step process, through a manifest file, or through a Unified FastIron Image (UFI).

  1. Preliminary checks. For any upgrade, review the information in General Considerations for Upgrade to or Downgrade from FastIron 09.0.10a or Later and then follow the instructions in Initial steps to determine the current software versions, license requirements, and instructions on where to download the software.
    Unless configured, syslogs do not persist across reloads.
  2. Upgrade the software. For a step-by-step upgrade, refer to The upgrade process.
    Note: Beginning with the FastIron release 08.0.90, UFI image copy is the recommended software upgrade method for both standalone devices and traditional stacks.
    Note: Beginning with the FastIron release 08.0.90, all new hardware platforms, starting with ICX 7850 devices, support only UFI images for software upgrade.
    Note: For a stack, you can perform a full manual upgrade for each unit, or you can download the software as described in The upgrade process followed by an In-service software upgrade for the stack as described in In-service Software Upgrade. Be sure to check ISSU Limitations and Considerations before performing an In-service software upgrade.
    Note: Beginning with FastIron release 09.0.10h, when the Telnet server is enabled, the configuration will follow through during the upgrade process to the FastIron release10.0.10. For earlier FastIron 09.0.10 releases or FastIron release10.0.00 with the Telnet server enabled, when upgrading to FastIron release 10.0.10, the Telnet server will be disabled. The Telnet server must be manually enabled once the upgrade is complete.
