I can disable IGMP snooping at Vlan level and/or port level. Sure, it's clear !
But it's not the ideal solution. Disabling it means flooding all multicast traffic. The L3 multicast traffic that is flooded and multicast could kill the wireless. Multicast is managed as broadcast on wireless AP. Broadcast is sent at the lowest data rate on the wireless side. This will have a bad impact on wireless performance.
At the same time flooding multicast could have impact on the entire network if there is an important multicast L3 traffic (surveillance camera / server)
Any other ideas ?
