You can install older Junos OS images on the Routing Engine with an upgraded i40e NVM firmware as it supports i40e 2.4.3 driver versions. If you install an older version of the VM Host image, which is not listed in Table 2, using USB, the Routing Engine does not start up properly. In such a case, you can reinstall the VMHost image with a version which supports the new i40e NVM firmware.

i40e-NVM upgrade is optional for the following platforms:

  • MX10003

  • MX10016/MX10008 with JNP10K-RE1 - shown in the cli output as RE X10

  • PTX10016/PTX10008 with JNP10K-RE0 - shown in the cli output as RE-PTX-2X00x4

  • PTX10002-XX

  • QFX1000, QFX10002

  • QFX5000

  • EX platforms

Note:
  • You must upgrade i40e NVM firmware only under the direction of a Juniper Networks support representative. Once you upgrade the NVM firmware, a downgrade action is not supported. For latest update, you can refer https://kb.juniper.net/.

  • You must implement this procedure with a router console access. Also, you have to perform power cycling of the routing Engine multiple times during the firmware upgrade process.

Before you begin upgrading the firmware, check the current firmware version of the i40e NVM.

If the value of Current version is less than 6.01, then you can use the following procedure for the i40e NVM firmware upgrade.

To upgrade i40e NVM firmware on routers with single Routing Engine:

  1. Upgrade the device with the Junos OS image version which supports i40e NVM firmware upgrade. See Table 1.

    Copy and install the jfirmware-vmhost package to the device.

    If the file has been obtained from JTAC, use FTP or SCP to load the firmware file on the device. Save the file in the /var/tmp directory.

    user@host> request vmhost software add /var/tmp/jfirmware-vmhost-x86-64-19.2R1.tgz

  2. Upgrade the NVM firmware.

    To initiate the upgrade, use the following command:

    Monitor the upgrade status by using the show system firmware command. If the upgrade is initiated the output displays PROGRAMMING (0%) as the status. However, note that the status PROGRAMMING (0%) does not increment during the process.

  3. Reboot the device by using the request vmhost reboot command.
  4. Verfiy the progress of i40e NVM upgrade on the console. You may have to perform power recycle of the Routing Engine multiple times. When you are prompted for a power cycle on your console, use external power cycle for power cycling the Routing Engine.

    The following message is displayed on the console prompting you to perform a power cycle:

  5. After a successful upgrade, verify the version of the firmware.
    Note:

    The Current version is displayed as 6.1 instead of 6.01.

    Note:

    In case, you have run the request vmhost snapshot command with a Junos OS image which does not support i40e NVM firmware upgrade, (if the SSD recovery snapshot has a Junos OS version older than the Junos OS versions mentioned in Table 2) we recommend you to take a snapshot using the request vmhost snapshot command again. Hence, in case of a recovery process, the SSD recovery snapshot will have a Junos OS image which supports NVM 6.01.

On routers with dual Routing Engines, you must use the request chassis cb (offline | online) slot slot-number to power cycle the Routing Engine. Thereby, you can avoid using an external power cycler and avoid abrupt power cycling of backup RE, which may cause file system errors.

To upgrade i40e NVM firmware on routers with dual Routing Engines:

Note:

You must disable GRES before proceeding with the upgrade procedure.

  1. Upgrade the device with the Junos OS image version which supports i40e NVM firmware upgrade. See Table 1.

    Copy and install the jfirmware-vmhost package to the device.

    If the file has been obtained from JTAC, use FTP or SCP to load the firmware file on the device. Save the file in the /var/tmp directory.

    user@host> request vmhost software add /var/tmp/jfirmware-vmhost-x86-64-19.2R1.tgz

  2. Upgrade the NVM firmware.

    To initiate the upgrade, use the following command:

    Monitor the upgrade status by using the show system firmware command. If the upgrade is initiated the output displays PROGRAMMING (0%) as the status. However, note that the status PROGRAMMING (0%) does not increment during the process.

  3. Switch to the backup Routing Engine by using the request chassis routing-engine master switch command to switch primary role to other RE (i.e, RE1).

    Note:

    This step is necessary, because in Step 6 you have to power cycle the Routing Engine which is undergoing the NVM upgrade (i.e, RE0) from RE1

  4. Reboot the device by using the request vmhost reboot command from the Routing Engine which is undergoing the NVM upgrade (i.e, RE0).

  5. Monitor the console output. You may have to perform power recycle of the Routing Engine multiple times. When you are prompted for a power cycle on your console, use external power cycle for power cycling the Routing Engine. Or, you can use the command request chassis cb slot slot offline as described in Step 6.

    The following message is displayed on the console prompting you to perform a power cycle:

  6. From RE1, power cycle the RE0 using following command request chassis cb slot slot offline.

    To power off RE0, use the command request chassis cb slot 0 offline and to power on RE0, use the command request chassis cb slot 0 online.

  7. After a successful upgrade, verify the version of the firmware.

    Note:

    The Current version is displayed as 6.1 instead of 6.01.

    Note:

    In case, you have run the request vmhost snapshot command with a Junos OS image which does not support i40e NVM firmware upgrade, (if the SSD recovery snapshot has a Junos OS version older than the Junos OS versions mentioned in Table 2) we recommend you to take a snapshot using the request vmhost snapshot command again. Hence, in case of a recovery process, the SSD recovery snapshot will have a Junos OS image which supports NVM 6.01.

  8. Similarly, while upgrading i40e NVM on RE1, power cycle RE1 from RE0.

  9. You need to perform this step only if the image you downloaded does not contain debugfs based mechanism to stop LLDP.

    Download the lldp-patch-for-i40e-upgrade.tgz package. Copy and install the file in the /var/tmp/ directory on each Routing Engine.

  10. Reboot the device by using the request vmhost reboot command. The upgrade process is complete when the Routing Engine comes back online.
