MagentaTV / IGMPv3 and SwoS 2.10 for CSS 326-24G2S still not working :-(

Thu Oct 10, 2019 5:05 pm

Hi there,

after over a year, I was absolutely happy to see the new SwOS Version 2.10 with a lot of IGMP related improvements, finally it might be possible to use the switch together with "magentaTV" from 'Deutsche Telekom' (aka. T-Online) which requires absolutely IGMPv3 capable switches to work...:
...
*) do not ignore RSTP port state when forwarding DHCP, PPPoE or IGMP snooped packets;
*) IGMP snooping: send out IGMPv3 queries by default;
*) IGMP snooping: handle IGMPv3 leaves much better;
...
But.... no.... Mikrotik does not get it again.....

I got a rather large home network with a couple of vlans, so I seprated the T-Online Magenta IGMP-'hell' in its own VLAN let the untagging be done by the switches.

So I got the following infrastructure
Dell Poweconnect 7024
Dell Powerconnect 6224
several OpenWRT based Atheros/Broadcom devices as accesspoints (Linksys WRT32X, TP-Link Archer C7)
plus a couple of Netgear GS108E for 'behind the TV'

and..... my Mikrotik CSS 326-24G2S for my Lab.... which is currently (again) freed from my vlan 30 to not interfere with the IGMP-hell.....

Dear Mikrotik Engineers: What is so problematic about the correct, working implementation of IGMP? Yes I know, I hate the protocol maybe as much as you do, because it is not really good from any point of view - but since IPTV is finally arriving and with gigabit internet connections it makes finally a bit sense....

Why works a 25 € Netgear GS108E from a flash-sale on Amazon works way better than my 150 € Mikrotik "professional" Switch?

Sorry for the rant here.... but I bought the Mikrotik device when it came out, because I was convinced, because I was working a long time with Mikrotik Wireless devices and routers, and the only downside of my Mikrotik RB260GS was the lack of IGMP support.... I thought the CSS 326 would be absolutely ideal for me - but it wasn't, it isn't and I doubt it will ever be :-(

I am thinking about buying the CRS305-1G-4S+IN - to use it as a 10 GB ethernet core-switch - but - currently IGMP related I think it acts absolutely as the CSS326 is acting, making my IPTV based on IGMPv3 unusable....

So, please, explain to me, what is the problem and how can *I* help to help you fix it? Is there anything I can do? Maybe a pcap dump with timestamps what happens?

Would be awfully nice of you to make it finally a 'good' switch....

Cheers,

I was also happy to see new firmware update, hopping that it will solve my issues with IPTV.
Well, it's better, IPTV finally works without everything freezing after few seconds of viewing, but it's still stuttering every few seconds.

Hope we won't have to wait for such a long time for update that will resolve IPTV issues, my CSS106-1G-4P-1S is nothing more than a paper weight.

I'm also willing to help however I can in finding what's the issue of our problems :).

We have included major IGMP Snooping improvements in SwOS 2.10 version. As kwinz already mentioned, if you still face some IGMP Snooping related problems, you should report this to support@mikrotik.com. A detailed problem description together with screenshosts, network diagram and packet captures would be much appreciated.
