Hi Krati,
Iperf does not support sending ARP floods. ARP is done by the kernel/os and
not at the application/iperf layer and only is needed once to build the initial
ARP cache. This is all done underneath iperf.
You can issue arp clears per the destination ip of an active iperf stream to
cause the kernel to rebuild the arp cache. It’s doubtful that the clears can
be done fast enough to meet your needs.

Subject: [Iperf-users] Generate ARP Packets
Hello,
I am working in Software Defined Networking(SDN). I have Opendaylight
controller, and created virtual topology of hosts and switches using
mininet(network simulator). I wish to generate huge traffic (send large number
of packets one at a time) in the network using iperf, so that controller is
loaded.
The only packets which go to controller is ARP requests or whoes flows is not
defined in switch.
How should I generate such packets using iperf?
Thanks,
-Krati
