V400 Stacking with two X690 and 3rd party optic

V400 Stacking with two X690 and 3rd party optic

does someone ever try to build a V400 Stack with two X690 and 3rd party optics? I use OEM QSFP28 Transceiver - Extreme 10403 Kompatibel 100GBASE-LR4 QSFP28 1310nm 10km.
In a native 100G Port we got a link at any time, but on the V400 stacking ports 61 and 69 the optic stay dark, no link. Does someone have any experience with OEM optics and V400 stacking?

Best regards
Andreas

Hi Axel,
many thanks for your reply. I hope they fix the problem soon.

Hello all having the same important issue with X590/690 stacking !

Here the current status:

  • All QSFP+ optics are affected, doesn not matter if original or 3rd party
  • There is no solution in EXOS 30.1 !
  • A Patch 22.6.1.4p2-1 temporarily solving this issue is available
  • the plan is to have this in 30.2 GA
I heared about a swiss hack to manipulate the QSFP+ to run with >106GBit, but I could not test this yet.

Hi Volker,

I'm curious about this "swiss hack to manipulate the QSFP+ to run with >106GBit"...

Can you provide some more info?

Hi,

Just to outline that this is QSFP28, not QSFP+. The 22.6p2-1 is indeed the solution at the moment.
