[j-nsp] JunOS on EX4550?

[Richard McGovern]

In my view best stability, used by most people (all of my customers are on 12.3 only), and no feature set differences. When 15.1 came out initially there were some concerns, so IMHO most just stayed on 12.3 once it was announced to have continued support.

Just my 2 cents worth.

Thanks, Richard.  Any particular reason why I would be better off using 12.3R12?

No.  For legacy EX switches, for which EX4500/EX4550 fall into, 15.1 is last release.  At the same time, I think you might have best results using 12.3R12-S[latest] instead.  Both 12.3 and 15.1 will be maintained for life of legacy EX switches.

I’d rather be lucky than good, as I know I am not good
I don’t make the news, I just report it

    Is it possible (and recommended) to run anything newer than 15.1 on EX4550
    (which is what the JTAC-recommended version currently is).
