IGMP/Multicast traffic sniffing


In HP5412R (J9822A) I've created VLAN with following options:


vlan 3
   name "Engineering"
   untagged A3-A20,B1-B24,C1-C24,D1-D24
   tagged A1-A2,A21-A22
   no ip address
   ip igmp
   ip igmp forward A2-A20,B1-B24,C1-C24,D1-D24,G14-G24
   no ip igmp querier
   qos priority 3

I would like to block IGMP packet sniffing between untagged ports. How can I do this?
