    I need to make a greater Downgrade to a smaller version on a switch extreme x440 , what is the procedure?
    Keep in mind that the version I want to get the just installed because of an error and should give isntalarla because I have not even restarting the switch and these teams are in production.

    Hello Jairo,

    What version are you coming from and going to? Can you please elaborate on "smaller" version?

    Can you give us the "show version images" and "show switch" output?

    Hello Jairo,

    It looks like it installed just fine.If you are trying to install a different image then you just need to go through the same process you went through to get 16.1.3.6 on the switch.

    Hi Jairo, you can use the procedure described in the article below:

    How to obtain a copy of the EXOS software and upgrade EXOS switches

    You can follow the same procedure described under "Software upgrade procedure"

    Just make sure to backup the configuration in ASCII and XML formats. It's recommended

    Please check the article below about how to backup the switch configuration:

    How to upload Backup Configuration to TFTP server on an EXOS switch

    Just follow the Method 1 step1 for ASCII and Method 2 steps 1 and 2 for XML

    Jairo:

    In the "show version images" output you provided, you still have 15.5.3.4 in the primary partition. Simply issue
    use image primary[/code]and reboot the switch. I presume this is the image you were running prior to the upgrade to 16.3.1.6.

    There's no way to roll back to whatever image existed in the secondary partition prior to your upgrade, but since EXOS does not allow you to install to an active partition, it's likely the primary is what you were running before. Once you're booted into the primary partition, you can download a new image into the secondary partition, using the article detailing software upgrade provided by Henrique above.

    Jairo:

    The screenshot you provide is absolutely correct and expected behavior.

    That partition has been written with the 16.1.3.6 image; it cannot be uninstalled, only installed over.

    If you wish to return to the 15.x image present on the primary partition,
    use image primary
    reboot[/code]
    And then you may install a 15.x image to the secondary partition, if you wish.

    You can use the uninstall image command to uninstall the ssh xmod, but not the base code in the partition.
