Question

How to change NIC speed from 25G to 10G

I have newly installed HPE DX380 servers, total 3 NODEs with 10G/25G Dual port NIC ports (2 Pairs = Total 4 Ports).

I have Mellanox Network switch which is configured with 1 to 12 port on 10 GB Network.

After installing the AHV,AOS & creating the Cluster, when trying to create the VS, it is showing 3 Network Cards in 25G group & 1 in 10G. Therefore I am not able to create a BOND. 

My question is, How come only one NIC is showing 10G speed & rest of them with 25G. Logically if I have already configured my Network switch with 10G speed for all the required ports, In Prism also it should reflect as 10G even if that NIC is supported 10/25G speed.

Does anyone have any solution for this. I am missing something? Can we change the NIC speed manually on each Node?

Thanks in advance.

are you sure that 4/4 NICs are able to support 10/25GB/s ? maybe you got ¼ different and that’s why you see it separatively ?

On the other side, from a network perspective, I assume you manually force throughput and duplex on the interface isn’t it ?

The following is the BOM details

NIC (OCP3) (Add-on): 1 x DX BCM 57414 10/25G 2p SFP28 OCP3 FIO Adp

NIC (PCIe) (Add-on): 1 x DX BCM 57414 10/25GbE 2p SFP28 FIO Adptr

Even if I try forcefully change the NIC speed manually by command with “ethtool” it gives the error for “br0” as well as individual “eth0”.

“br0” is a default BOND including all 4 NICs.

The following command was tried using “sudo” also with no result.

# ethtool -s eth0 autoneg off speed 10000 duplex full

cannot get current device settings: Operation not supported

not setting speed

not setting duplex

not setting autoneg
