Switching

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.

May i know on which ex switch model are you tyring to configure mixed speed ae?

Mix speed ae is not supported on EX platform as far as i know

HTH

Thanks. This was on a pair of 9208's.

No, it's not supported on that platform

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.

Hi,

Link-speed mixed option is not available in 15.1 as well

Junos: 15.1R6.7

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