PROCESSOR-SDK-AM65X: Simultaneous Ethernet problem

Part Number: PROCESSOR-SDK-AM65X

Hello,

I'm trying to confirm performance of simultaneous ethernet behavior.

Here is my configuration.

* SDK : Linux SDK 6.00.00.07

* I used iperf3 to confirm ethernet performance.

  However, when I connect to eth0 to PC1, PC2 and eth2 commucation error is occurred.

  After that, I disconnected cable between PC1 to eth0 and re-connected PC1 to eth0 again, PC1 and eth0 commucation error is occurred(On the other hand, PC2 and eth2 commucation became fine by using iperf3.) at this time.

 I confirmed "ping" is also failed. So I guess that we can not use ethernet port at same time at current SDK.

The question is

* Can we use simultaneous ethernet communication at SDK 6.00.00.07 ?

Best Regards,

    Hi,

    your IP configuration is the issue. You're using the same subnet on both interfaces. If your target needs to send a packet to PC1 (192.168.11.2) or PC2 (192.168.11.3) both eth0 and eth2 would be viable choices, and Linux is going to use only one of them.

    Could you repeat your test with a different subnet, e.g. 192.168.12.0/24 for PC2 and eth2?

    Regards, Dominic

    Hi,

    I agree with what Dominic is saying concerning the problem issue.  If this is still an issue after setting up different subnets please respond, in the meantime I will close the thread.

    Thanks Dominic for your contribution!

    Best Regards,

    Hello All,

    Thank you for your suggestion.

    As you said, I changed subnet address of one of my PC, then I could observe expected result.

    So, I will close this therad. Thank you !
