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.
