[j-nsp] LACP on mixed virtual chassis QFX5100/EX4300

Have you tried just setting the EX side and leaving the link-speed statement off of the QFX side, since the QFX interfaces are hardcoded to auto negotiate only that might work?

As far as I know there is no way to set the link speed (only the link-mode
for duplex) on the underlying interfaces in a AE bundle (and they are always
labeled xe-), at least on the code I am running on the QFX5100-48T.  You ca
specify the link-speed for a AE interface which I presume sets the speed of
the underlying bundled interfaces, but I have not tested this out as I have
no EX switches.

set ae9 aggregated-ether-options link-speed ?


If you set the speed to 1G for example, the commit script failed because of the xe- interface seen as a 10G interface.

And yes, the speed is blocked as auto (in the show interface extensive | match speed)
