IGMP Snooping JGS524Ev2

Hi,   I bought 4 Netgear switches ( 3x JGS524Ev2 and 1x JGS524PE) and I am trying to setup IGMP to work properly. At the moment the settings look like this on all switches https://imgur.com/a/2e0Uz...

    All switches require the same IGMP snooping config - otherwise thier ports will be flooded (as you have seen).

    And yes, IGMP snooping can be enabled on one VLAN only - if there are multiple VLAN you have to define the VLAN.

    Multicast groups are a different thing, and vase on the addresses (on the same VLAN).

Hi schumaku ,

 

Thank you a lot for suggestions. All working as it should now. I did also set up port 24 for all switches to be the IGMP routing port and did block all the unknown mcast addresses. 

 

Works like a charm.

 

Thanks.
