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

Solkre — Fri, 15 Sep 2023 03:35:34 GMT

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

1/2/4 39535845 44427007 228 0

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.
