    I'd like to temporarily mix 10Gb and 40Gb interfaces on an ae interface during an upgrade--can I safely do this? What do I set  link-speed to?

    I guess, link speed mixed is enough.

     

    set aex aggregated-ether-options link-speed mixed

     

    You can refer to below links for more understanding.

    Thanks for the links, unfortunately speed mixed does not appear to be an option on EX.

    What version of EX9200 SW are you using?  I would think you need to be on 14.2 or higher.  I assume you are saying that the command:

     

    set aex aggregated-ether-options link-speed mixed

     

    Either errors or does not commit, yes?  I do not believe there is any [SW/commit] restriction that would not allow a mixed speed AE to be formed, but I also believe there is nothing in the hash algorthum that would take into account speed of link without above knob being set.

     

    I really think this should at least commit and work, now work-well (and supported) could be something else.

     

    Have you tried it?

    I only looked at speeds available from autocomplete (17.1 btw), but it actually does appear to be a hidden option that passes commit check. I don't need it at this point now so I'll leave testing up to someone else... Thanks for the follow-up.

    Maybe hidden?  I find it hard to believe function there on MX and not on EX9200, but could happen.
