I want to connect N3K-C3064TQ-10GT and WS-C4500X-40X-ES with qsfp-4sfp10g-cu5m. Will such connectivity work?

As I understand I can split QSFP port on nexus as separate 10G interfaces and maybe it will work, but 4500x datasheet don't tell me anything about support of such cable type.

Well, mine works fine (N3K

Well, mine works fine (N3K-C3064TQ-10GT and WS-C4500X-40X-ES), but I think you need:

1. Version 03.06.00.E must be updated to latest for sure, since it very outdated.

2. Check release notes for you Nexus gear. 

3. If it possible to check cable with/between another devices - do it.

If it won't help, you need contact TAC and maybe this is case for RMA.
