IGMP Support for managing multicast traffic

Switches
1

Has anyone managed to try out one of these switches in a network using multicast?

Interested in how configurable they are from the cloud management in terms of IGMP Snooping, Querier and some equivalent of ‘fast leave’ to prevent ‘unrequested’ multicast traffic from being sent over ports.

Thanks

We don’t yet have IGMP Snooping support, but it will be added soon. No explicit plans with IGMP Querier or fast-leave support, but I did ask and we’re investigating. I’ll follow up once when I have more details to share and/or IGMP Snooping support is added.

Ah ok, that’s a shame. I work with a lot of devices that use multicast, so good IGMP support is a firm requirement. I work from home, and my home network consists of at least 4 switches, so just having IGMP Snooping wouldn’t be enough unless IGMP Querier was also present I don’t think.

Thanks

I can certainly understand the need and use. I will follow up when I have more information to share.

In the Netherlands this is required if you want to watch IPTV through your ISP in combination with a fiber connection.

@Alta-MikeD any updates on this subject?

Today we released switch firmware 1.2j, release notes HERE. We added support for IGMP/MLD Snooping, Querier, and also Leave messages.

This is great news. Anyone with multiple switches confirm that it does what is expected?

Thanks

Multicast through an UDMP > S16-POE > S8-POE > KPN TV+ IPTV receiver.

Channels show up under two seconds and streaming apps (Netflix and Spotify) work.

In particular I’m interested in whether the switches correctly drop multicast traffic for ports that aren’t requesting it. It’d need a bit of Wireshark work, possibly combined with something like VLC to request streams to prove.
