Need help configuring X710-DA2 with Cisco SFP-10G-SR SFP module

[RHick1]

Hello,

I am trying to test that I can send and receive traffic on my X710-DA2 NIC

- I am using CentOS 7

- Using

ethtool -p p1p1 successfully lights the LEDs associated with the p1 connection

ethtool -p p1p2 successfully lights the LEDs associated with the p2 connection

- I have a Cisco SFP-10G-SR module installed in each of the ports on the X710-DA2

- I tried

a loopback cable (TX to RX on p1)

looping the fiber optic cable from p1 to p2 connecting RX to RX and TX to TX

looping the fiber optic cable from p1 to p2 connecting RX to TX and TX to RX

None of this worked ...

It was suggested to me that on the X520 card I may have to use ixgbe to set the switch to allow_unsupported_sfp=1

Is there something equivalent for the X710-DA2 ???

Thanks,

Roger

Hi roger_h,

Thank you for the post. It is recommended to use supported Intel fiber module for X710-DA2.

Here is the reference link for the supported Intel fiber module:

Hi,

Thanks for the response. New to the networking world so forgive my naivety

1) I have a CentOS7 Linux box with an X710-DA2 NIC. If I now use Intel E10GSFPSR (SFP+ SR Optic) modules and loop port 1 to port 2 through OM3 MMF, I should see a connection?

2) I am in development mode and would like to get by this roadblock while my order goes through purchasing. Is there some way to get the X710DA2 to "allow_unsupported_sfp=1"?

Thanks,

Roger
