Hi,
the same could be, in theory, done using generating UDP traffic to a broadcast
address ... those packets won't get routed by L2 switch either. However, this
kind of operation would just load all the network interfaces without any
service impact. If your goal is to test ARP functionality on that particular
server, then iperf will not help you.
Iperf doesn't seem to support client operation with broadcast address as
"server" address, hence it won't help either.
BR,

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
