Thank you for the advice. Actually, *setting* autonegotiation did the
trick.

  set interfaces xe-0/1/4 gigether-options auto-negotiation 
  set interfaces xe-0/1/5 gigether-options auto-negotiation

The plain LAG without LACP seems to be working, I disabled/reenabled
in turn each interfaces and the link kept UP.

I feel ashemed not to have thinking about autoneg before, as it wasn't
necessary on the native 1G port of the MX5.

Thanks again to everybody!

Cheers,
