I've got the very latest code on as it's in a lab D25

I've got two 3rd party DACs and it's going from QFX5100 to QFX5100. Both have the same issue. Same two cables in QSFP ports on the back of the 4300s works perfectly fine.

What version of code? D10 (frs) had some issues with some cables which is resolved in more current versions.
Also if this is 5100 to 4300 make sure you have auto negotiation turned off on the 4300 (but that would probably fail with a juniper branded dac as well so unlikely to be the issue).

Anyone having any luck with this? I've got a few QSFP DACs that work perfectly fine on a 4300 stack, but the QFX5100 refuses to work with them. Work fine with a Juniper branded DAC.
