    I have a few Netgear 105E/108E switches that do IGMP Snooping to hopefully reduce the floods of multicast to ports hosting e680's that do not need to receive universe data for. However, I'm having trouble getting multicast forwarded between 2 or more switches. I can get ports to forward data while all controllers are all on the same switch, but not if I uplink to another switch. I've not set up any VLANs since everything is in a single broadcast domain, thus all ports should be in the default vlan. Is anyone using these switches with IGMP snooping through multiple switches? If so, what multicast settings are you using?

    First question is do you *need* igmp control?


    100mbps can handle a lot of universes.

    I found the issue. One of the switches had 'block unknown IGMP requests '. I disabled that and everything worked.
