I have a strange issue getting Cisco SFP+ DAC cables to work with Intel X710 adapters!
I got two series from the supplier BUT same part number SFP-H10GB-CU5M
One of them is working perfect and the other no!!!!!!!
After connecting them to Cisco switch, it displays just a difference in VID, please checkbelow:
Thank you for posting in our Intel® Ethernet Communities Page.
Our X710 adapter is only compatible with Intel branded SFPs. For more information, you may check this page, https://www.intel.com/content/www/us/en/support/articles/000007045/network-and-i-o/ethernet-products....
Although there are some reports that other brands worked after they upgraded the firmware, the reports are unconfirmed and varying results may happen.
Did this SFP worked before? If the other one worked and this one did not are you able to test another model of this one?
We look forward to hearing from you. If we do not get your reply, we will follow up after 3 business days.
