Configuration > IGMP Snooping 
With Internet Group Management Protocol (IGMP) snooping, the 
Web-Smart Switch can make intelligent multicast forwarding 
decisions by examining the contents of each frame’s Layer 2 MAC 
header. 
IGMP snooping can help reduce cluttered traffic on the LAN. With 
IGMP snooping enabled globally, the Web-Smart Switch will forward 
multicast traffic only to connections that have group members 
attached. 
Please note that IGMP will not alter or route IP multicast packets. To 
send IP multicast packets across subnetworks a multicast routing 
protocol will be necessary.
