Hello

Maybe I have mis read your requirement - I was on the understanding you are trying to prohibit an host from receiving igmp requests

You state igmp snooping is enabled, if so is it also enabled for a specific vlans?

Could you possible provide a more detail explanation of what you are actually trying to achieve ?
