Dear Taeheum Na,

 

There are couple of ways using Iperf (GUI with java app – Jperf in windows
and CLI as you did).

Moreover, you should check the listening port.

Make sure of that you can try:

          Listener VM:   iperf –s –u

          Sender VM:    iperf –c –u IP_of_listner_VM

So iperf will use the defaul port 5001.

 

Hope it can help you out.

Cuongtm,

Subject: [Openstack-operators] Iperf isn't work between VMs which are placed
in other host

 

Hello, I tried to measure network performance BTW VM which connected through
GRE tunnel. So, I configured neutron(ML2/GRE). 

Then I verified TCP performance between VMs which are placed on same host. 

But I could not make Iperf connection BTW VMs (on other host), but ping is
ok.

bellow things are current Security group configuration. I think that I allow
all traffic which is needed to execute iperf.
