Configuration > IGMP Snooping > IGMP Snooping
With Internet Group Management Protocol (IGMP) snooping, the DGS-1210/ME Metro Ethernet 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
DGS-1210/ME Metro Ethernet Switch will forward multicast traffic only to connections that have group
members attached.
The settings of IGMP snooping is set by each VLAN individually.
