Thanks it is useful. Can anyone help with commands to send multiple joins and traffic for multiple groups. Say 226.1.1.1 to 226.1.1.100 |
commented Oct 9, 2018
There isn't a way to join multiple groups other than to start multiple servers. It could be added thought, e.g. something like iperf -s -u -B 239.1.1.1-100 or equivalent. To transmit to multiple groups one can use iperf -c 239.1.1.1 -P 99 --incr-dstip I've been doing a bit of fix ups in iperf 2.0.13a so it's a good time to add the multiple group join if it's useful.

It works with iperf-2.0.12. Thanks Bob |
commented Oct 29, 2018
Hi Bob, Please share if you have fix ready to add the multiple group joins. Will iperf-2.0.12 for multiple group joins? |
commented Nov 12, 2018
I haven't coded this up yet. It won't be releases with 2.0.12 but rather in 2.0.13 Bob |
Are there any multicast traffic generators for Windows?

Multicast traffic is actually pretty simple to create with any programming language. If you got python installed here's an example, I hope it works under Windows.

Save it to i.e. mcast.py and execute it like this:
Change TTL in the script if you whant the traffic to reach further down in the network.
