Configuration Igmp Snooping | D-Link DES-1252 instruction

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.

By default, IGMP is Disabled. If Enabled, the IGMP Global Settings will need to be entered:
