I am trying to simply push multicast traffic through the second switch of the router... for now I connected swtich 2 port 8 to my ISP router iPTV port and port9 to SagemonUHD88 IPTV decoder. I set master port port 6, and added slaves port 8,9.

I removed all ports in switch2 from default bridge (no bridges beside). After few second of multicast traffic the log clamin link down... and goes on an on every few second. I tried firmware 6.38.5 and 6.37.5. Both the same issue.

Just to be sure, I got connector between two RJ-45 plugs so when I disconnect the cables from mikrotik and connect it directly it works without any issues (I mean, the video on TV goes smoothly, no breaks).

I wanted it to just have wirespeed. When I will replace the default router (the Livebox 2.0 fro my ISP) i will try push tagged vlan with that multicast and untag on the port to the IPTV decoded. However for now I am now able to do that and as far as I see RB2011 can only tag frames on the way out from switch (egress), so no way for internal tagging the frames from specific port.

The answer is, that version 6.38.5 , 6.37.5 , 6.39rc5 all contain the same issue with pushing multicast on RB2011 to 'switch2 cpu'. They claimed that it had been nailed and fix is going to be a part of the next release. EOT

EDIT: Already checked, the provided fix works:

What's new in 6.39rc62 (2017-Apr-04 14:09):
*) ethernet - fixed rare switch chip hang (could cause port flapping);
