Extreme Switch x670 bandwidth limited to 3g insted of 10g

[philippe_page]

I would like to ask some question regarding our switch. I am testing the bandwidth of our switch. It is currently configured with 10g without any limits on its egress and ingress. However I am only able to get 3g bandwidth instead of 10g. I'll attach the port info detail here for further details:

Do you have a lot of experience with iperf? I know there are ways to configure it to make sure it really tests throughput. Also, do other ports in your network perform at 10 with the same iperf setup?

Im using the same extreme switch for different racks. I still cant seem to identify what is causing this issue. I've look into auto negotiation and jumbo frames but still bandwidth is still limited to 3g instead of 10g

What version? We used to have a licence for 10G for unsupported optics, but that has since been removed in more recent versions of code

Im using iperf3 on our servers connected to the switch. From one rack to the other. It is weird because when I am testing inter rack bandwidth it was able to show 10g but when I am testing on 1 rack it is limited to 3g only. I am looking for some difference in the switch configuration and I was able to find out that there are jumbo configured on the other switch. I was able to configure it also on the switch which was limiting me to only 3gb but I still get the same results.
