Hi, Reza
You got port stats through your Ryu application, right?
If so, could you try to get rx_dropped and tx_dropped directly from the
switch?
If the switch shows that rx_dropped and tx_dropped are zero, the
behavior of Ryu is right.
In this case, you should check if packet loss has occurred in other
place than the switch, or ask the support team of your switch.
If you are using OpenVSwitch, 'ovs-ofctl dump-ports [switch name]' will
show the information:
Thanks,
Fujimoto

Hi all,
I am using D-ITG to generate traffic in my Mininet network. The D-ITG
log show 3% packet dropped, but when I look at the switchs' port stats
both rx_dropped and tx_dropped are zero.
I am curious to know why the results are like this? shouldn't port
stats show these packet losses?
Thanks,
Reza
