Nic always setting it self up and down

CEyig — Tue, 22 Aug 2017 18:49:15 GMT

Hello ,

We are using an X520 intel 10Gbps dual nic.

It always returning this kind of errors and causing big latencies on the network at the up / down times . This especially happens under high load .

Thank you for your help

HI SPDNet,

Thank you for posting at Wired Communities. Can you share additional information for us to investigate?

1) What is the driver version?

2) Understand it is an X520 server adapter, can you provide the serial number, this can be found on the physical network adapter with white sticker consisting barcode, the serial # is like 12 aphanumeric + 5 alphanumeric + 6 digits - 3 digits

3) What is the exact Linux version?

4) What is the brand and model of the switch ?

5) Have you try changing the cable to test the connectivity?

6) How about the module? Have you isolate the issue if the modules are working fine with other X520?

Please feel free to provide more information.

Thanks,

sharon
