These are not errors. Your hosts are bouncing. It might be up right now but it was bouncing. If it is a FEX issue, it will happen to all the interfaces in the same ASIC.

Something plugged into port E106/1/2 and E106/1/3 is bouncing. Those messages (I will not call those errors) are interface up/down events. Can you check if there are anything connected?

Fiber to N7K? I am not 100% sure how you have your switches configured and connected. Yes, you can try to swap out the cable to see if it improves or not.

Same story on port E107/1/2, it is bouncing, check your connection.

108545 Eth107/1/2  down*  failed      Consistency Check Not      -

                                                             Performed

This output is normal when an interface is down under show vpc.

It would be anything. Cable, configuration, bad hardware, etc. You need to eliminate one element at a time to find the bad component.
