SFP+ 10 gig issue

[LineOne]

We have a TEG-30262 Trendnet switch - with 2 SFp+ 10 gig ports. We also have a quad-port Intel 10 gig adapter - Intel X710-DA4 NIC - on a Supermicro - Supermicro X12SPO-NTF- motherboard.
We are running Windows 2019 server. We have two of the Intel ports plugged on the server plugged into the 2 10 gig SFP+ ports on the switch. The cable used to plug in is

10Gtek 10G SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU3M, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, ZTE Devices, 3m…​

Windows sees all 4 NICS but says only one is plugged in. All the lights are on at both ends of the connection.

What could be the problem? Do we have to do some bonding/teaming/link aggregation - the switch is a dumb switch so there is no configuration possible on it. Can we use both 10 gig SFP+ ports simultaneously or might one be reserved for connection to another switch?

Also on the one connection that is working properly we are experiencing 3 per cent data loss.

Should we be using a different cable? The distance is 3 meters.

Thanks in advance for your attention to this.

Hi Line,

Greetings for the Day!

Hope you are doing well. This issue could be due to several reasons:

- Ensure that the cables are securely plugged in at both ends.
- Check the drivers for your Intel X710-DA4 NIC. Make sure they are up-to-date.
- Test the other ports on the NIC to see if they work individually. This can help isolate if the issue is with the NIC or the cable.

For data loss, please:

- Verify the quality of the cable. While 10Gtek cables are generally reliable, it's worth testing with a different cable to rule out any issues.
- Ensure that the NIC and switch are both configured for the same speed and duplex settings, as mismatched settings can lead to packet loss.
- Check for interference or environmental factors that could affect the cable's performance.

Please do not hesitate to contact us; we are more than glad to assist you.
