</span>Hi!<br>
<br>
I don't need this box to respond and/or generate IGMP queries.<br>
I just need to snoop them in order to prevent unnecessary multicast<br>
flooding over all ports in certain VLAN.<br>
<br>
Again, my configuration is:<br>
<span class=""><br>
!<br>
vlan 450 name ITCons2DS_test<br>
tagged ethe 7/1 to 7/2 ethe 9/5 ethe 11/2 ethe 12/8 ethe 13/8<br>
multicast passive<br>
</span>!<br>
<br>
That's all. No any L3 multicast routing. Just IGMP snooping.<br>
<br>
And with such configuration my MLXe-16 starts switching multicast<br>
packets by LP CPU.<br>
