ICX-7250-24P Input errors on SFP+ ports with DAC cables.

[Solkre]

I'm running a ICX7250 just for the 10Gb ports.  I have DAC cables going to other devices that are Unifi.  A UDM-Pro and a USW Enterprise 8 PoE.  The Unifi hardware show no errors input or output.

On the 7250 I'm getting a very low, but consistent number of input errors on ports 1/2/2 and 1/2/4.  Port 1/2/8 is using a 10Gb RJ45 module and doesn't give me any trouble and is connected to a server.  I imagine by % these errors are harmless but they're annoying to see.  Any suggestions on what I could do?  The DAC cables are these.  https://www.amazon.com/gp/product/B08YNHZ8TK

I comprehend that you're facing input errors on ports 1/2/2 and 1/2/4 on icx 7250 .
So the DAC cables that you are using is not ruckus . Hence in order to isolate the issue I would suggest
you to use ruckus dac cables and let us know if the input errors are reduced or not .

Adding to the post. You can also use the below commands to understand more about the traffic and further isolation. It is recommended to use Ruckus transceivers/DAC cables with the Ruckus devices and the below commands will help you compare your existing transceivers/DAC cables with Ruckus transceivers/DAC cables in case you switch to Ruckus transceivers/DAC cables. 

If both ends are connected to Switch. Below commands to be check from end to end on both switches. 

Commands:
