Iperf 2.0.10 <https://sourceforge.net/projects/iperf2/> supports ip
multicast. For example, to receive multicast on 239.1.1.1. issue
- iperf -s -u -B 239.1.1.1
where the -B binds the multicast address to the host. This is required
for the server to receive multicast. And to send issue use:
- iperf -c 239.1.1.1
Make sure your system has multicast routes set as expected. If there is an
L2 ethernet switch in the path you might want to start an IGMP querier near
the client, enable IGMP snooping and set its multicast router port
<https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/configuration/guide/cli/CLIConfigurationGuide/IGMPSnooping.html>
.
Note: I've contemplated supporting a simple IGMPv2 querier thread on the
client when the -c address is multicast. I haven't committed this code
into the code base. Let me know if that's something you need and are
willing to beta test. It probably would look something like
- iperf -c 239.1.1.1 --igmpv2_querier <period in seconds>
This all should apply to ipv6 as well though one needs to use v6 mcast
addresses
