HowTo Uninstall ONIE/Cumulus and Replace it with MLNX-OS

Hi everyone,

I’am in phase to buy 4 x SN2100-CB2FC, so delivered with a preload Cumulus.

  • 3 of them will be mainly used for training / testing / labs with my students and professionnal learner.

  • The last one will be, perhaps, used in my own stable environnement. (Yes ! 100G are awesome to play with !)

My questions are:

1/ I would have to regularly reset three of them in order to go back to a ‘‘clean’’ environnement.

I have read many things about it, but apparently i will need to ‘‘reactivate’’ the Cumulus license each time i reset. Is it right ? If so, is it always the same key or do i need to call Mellanox each time ?

2/ On the one that will be used for myself. I would like to uninstall ONIE/Cumulus and replace it with MLNX-OS. Cause i am mainly familiared with it.

Is it possible ? In my opinion, reading this article : HowTo Uninstall MLNX-OS and Install ONIE on Mellanox Switches https://community.mellanox.com/s/article/howto-uninstall-mlnx-os-and-install-onie-on-mellanox-switches , it looks…

Do I need to purchase a licence of MLNX-OS ? Or will it be integrated (’‘offered’’) with the switch, as this is a Ethernet switch ?

Many thanks for all your responses !

Sincerely yours !

Answer - Same cumulus license file will work every time on the same switch

Answer - Please contact support@mellanox.com mailto:support@mellanox.com for this support contact question - please mention the Switch PArt number you are planning to buy

Hi,

As you requested me, i’ve emailed the Mellanox support regarding my second question.

I’ve sending them the link to this community thread in order they can also have the context of my questions…

The only thing they say me is :

" According to our CRM records we could not locate any valid contract for you, please use our community portal or contact our

contracts department If we mis-identified your account, please send us your account name and contract number in order to proceed."

Sorry, but they are not professionnal at all, cause it’s not a support question but a pre-sale question, although it deals with the “technical” field of your product.

In conclusion, who can, or WANTS, to respond to my second question, without having to first pay a $$$$ contract, before possibly buying ??!!

Sincerely yours.

Thank you very much for your quick response and your professionalism!

Best regards.

Hi Fabrice,

someone will respond through the case.
