production: cisco 6500 WS-X6548 modules
test : cisco 2960g
Both have igmp snooping manually disabled.
Note that my main problem was that, when shutting down a node of the cluster, after 2 min, all nodes linux bridges blocked the multicast traffic.
Now, I see that old kernels (include redhat), send igmp queries by default when igmp snooping module is enabled
This behaviour have change last year,
Because it can conflict with igmp of physical switchs
