DHCI Proliant DL380 NICs flapping with M-Series switch

[jchen522]

The NICs in my proliant servers in DHCI setup are flapping.
The servers are connected to HPE M-series switches.

These are the HPE BLc 40G QSFP+ 4x10G SFP+ 3m DAC cables splitted into four 10 Gb.

One site has two SN2100M switches and the other site has two SN2410M switches

All four switches running Onyx 3.9.2210 code.

Each servers has two HPE Eth 10/25Gb 2p 631SFP28 Adapters

I tried the command

interface ethernet 1/1 speed 10G no-autoneg force

according to this article

https://support.hpe.com/hpesc/public/docDisplay?docId=a00072272en_us&docLocale=en_US

but it is still flapping.

Any ideas?

Hi

Are you using the same HPE BladeSystem c-Class 40G QSFP+ to 4x10G SFP+ 3m Direct Attach Copper Splitter Cable on the other working setup?

What is the Operating system installed?
If it is VMWare , Did you check if the driver and firmware version of the network adapter are compatable.

If the other setup is working with the splitter cable, please log a case with HPE for further analysis.

If the HPE BladeSystem c-Class 40G QSFP+ to 4x10G SFP+ 3m Direct Attach Copper Splitter Cable is not used , can you try swap the DAC cable and check.

You can log a case with HPE networking team and see if you see the flapping on the switch too.

Cheers
