Mellanox Technologies MT26428 and MT27500 Communication Status Check

The transmission speed of MT27500 in MT26428 is high, and the transmission speed of MT26428 in MT27500 is slow.

The OS of MT26428 is RHEL 6.4, and the MT27500 OS is Oracle linux 6.6.

I tried to update MT26428 firmware and driver by version and it is the same symptom.

Is it possible to communicate with MT26428 and MT27500 with ip in mstflint command?

And the image types are different. MT26428 is FS2, MT27500 is connectX. Does it matter?

Can you elaborate on the issue you are encountering ?

Which Traffic are you running ?

Did you try to install the adapters on similar servers with the same OS/Kernel/driver ?
