Nexus 9336c-fx2 with QSFP-4SFP25G-CU and 10G

[vsi]

Hello,

We have a bit of a situation where I have few of Nexus 9336c-fx2 switches and I'd need to connect a stack of hosts with 10G (Intel) NICs. Now, according to my understanding the Cisco QSFP-4SFP25G-CU -breakouts should work fine with those 10G NICs, simply based on the physical compatibility and pinout of the SFP28 vs SFP+, does anyone have any experiences with this sort of combination?

Thanks

Darn it.. Forgot to mention that I am obviously assuming 10G connectivity, not 25G - e.g downwards compatibility, and breakout configuration with 4x10G mapping.

I don't see any reference that this cable can do10Gig. It seems that it only brakes a 100Gig connection to 4 25s and not a 40 to 4 10s.

HTH

I need the same.

I'm looking for a data / spec sheet for the QSFP-4SFP25G-CUxM calling out the QSA to use and the compatible SFP+ transceivers because the 9336s Datasheet says "1/10/25/40/100-Gbps Ethernet Breakout supported on all ports, 1-36: 100G, 40G native, 4x10/25G (10G w/QSA) 1G w/QSA except ports 1-6 and 33-36"

We have servers with 10GbE SFP+ ports within 2 cable meters of my pair of Nexus 9336-FX2s.  While I would prefer to use DAC, the fact we have SFP+ means we can go SR if we must.

Hello,

I actually forgot to update the situation.

As it turns out, breakout cables in question worked fine in 10 Gig setup, at least in our scenario.

Thanks.
