Issues configuring 40GB network

Hello all,

I have just joined a company that has a 40Gb network configured using Dell S6010 switches.

Now we have just bought a new Dell S5232F switch that should be connected to that network but I am having issues with it.

feature auto-breakout is enabled and when I connect one of it's interfaces to a computing nodes 40Gb network card, it's correctly detected and status up and speed 40Gb can be observed in the outputs.

It's just these switches are not compatible between them or I may be missing something out?

Any bit of light would be really appreciated.

Jose
