XL710 no connectivity with Brocade ICX 6610 switch

I'm having the following symptom: Host 1 has a Intel XL710 card installed. If I connect the host to a Brocade ICX6610-48P switch via a 1m QSFP+ DAC (tried both a QSFP+ and a QSFP28 DAC), ethtool ...

Hi KaneTW,


Good day and thank you for visiting Intel Community Support.


understood that you are having an CRC errors on your XL710 card. For this matter, please kindly help to gather the SSU logs for us to analyze further on the NIC. Refer the link below on how to gather the logs:


https://www.intel.com/content/www/us/en/support/articles/000008563/ethernet-products.html


Additionally, may I know previously if the NIC was running fine without the CRC errors? Was there any changes made recently that could cause the CRC errors to be prompted?


Understood that you have tried different QSFP DAC cables but issue persisted. Can you confirm if you are using compatibles DAC cables for the NIC? Refer the link below for the compatibility of the DAC cables with the XL710 card.

Thanks,

Hello Faez,

I've ran the SSU utility. Please provide a way to upload the data, along with the debug utility data.

The NIC has not been used before, and is failing only with this particular switch. In addition, I constructed a layer 1 network tap using a FPGA. When using the network tap, which links two PHYs directly and does nothing else, connectivity was established. The CRC of the received and transmitted packets was also correct.

I am using compatible DAC cables.

Best regards,
