Greetings to all!
I have a 6001 running 7.0(2)N1(1) and I'm running in to an issue or at least I think I am.
Here is a napkin drawing of the topology.
Attached is more details on the Panduit cable. It’s really just a hydra cable (1x40G breaks out to 4x10G). I’m working on getting the details for the 10G card that is in the server. I don’t’ think I’ll have that until Monday from my server team.
On the switch side there is no config as I’m just trying to get the link to come up at layer 1.

The server admins said “they look ok, but they are not showing link up from dmesg”…

What I think I should be seeing on the 6001 side would be interfaces like 2/4/1, 2/4/2, etc just like I was using a QSFP-4SFP10G-CU5M. Can anyone help me confirm that is correct?
Please let me know and thanks for your help!

Greetings to all, I posted this issue on the troubleshooting forums and someone responded with this answer...
Since you are connecting a 40Gig interface to 4 10Gig you need to add this command
interface breakout slot 2 port x-x map 10g-4x
to make interface 2/4 to 2/4/1, 2/4/2, 2/4/3 and 2/4/4
link to document:
Thought I would share just in case someone comes asking the same questions.
