Hi!

I don't need this box to respond and/or generate IGMP queries.
I just need to snoop them in order to prevent unnecessary multicast 
flooding over all ports in certain VLAN.

Again, my configuration is:

!
vlan 450 name ITCons2DS_test 
 tagged ethe 7/1 to 7/2 ethe 9/5 ethe 11/2 ethe 12/8 ethe 13/8 
 multicast passive
!

That's all. No any L3 multicast routing. Just IGMP snooping.

And with such configuration my MLXe-16 starts switching multicast
packets by LP CPU.
