Hi, The querier is used when there is no multicast router on the VLAN, so if there isn’t you will want to use it and give it an ip with ip igmp snooping vlan vlan-id querier address ip-address If you do have a multicast router, it is not needed and the configuration you have done should work.

Hi all, What's needed to enable IGMP snooping globally on 5548p switches running 4.1.0.8 from a shell? This is what I've done so far: (config)# ip igmp snooping (config)# bridge multicast filtering (config)# end # copy running-config startup-config Do I have to run "ip igmp snooping querier" too? Anything else?
