Hi Team,
we have a Symentac Ghost application using which I am trying to do a multicast of an image to some users who are on same switch.
However, it is unsuccessful. the same is successful over different site 3850 switch. I am unsure if there is any IGMP/multicast configuration in the switch is missing or incorrect. Need your expertise advice asap.
when I initiate transfer to 3 users at once, the ports they are directly on are flapping, I enabled debug on IGMP and have seen below logs. Not sure what exactly they mean.

Please find some IGMP commands output if that helps.
