Hi,

I have 3 switches connected via OVS like this:

R1 -- R2 -- R3

I am doing an iperf test using TCP between R1 and R3. R1, R2 and R3 are
spread out geographically and i use a VXLAN tunnel to connect them.

iperf test shows me considerable packet losses. However, ovs-vsctl get
interface stats is showing me zero losses on all the legs.

This means that OVS for example on R2 forwarded all the packets that it
recieved on the VXLAN tunnel from R1 to R3. Is my assumption correct. This
means that the packet losses reported by iperf are the packet losses in the
network and not because of OVS.

Besides interface statistics is there any other way to get packet drops by
OVS?

Thanks, Abhishek
