multicast packets will only be forwarded to those ports containing multicast group hosts or
multicast routers/switches, instead of flooding traffic to all ports in the subnet (VLAN).
Basic Configuration for IGMP Snooping
Use the IGMP Snooping Configuration page to configure global and port- related settings
which control the forwarding of multicast traffic. Based on the IGMP query and report
messages, the switch forwards traffic only to the ports that request multicast traffic. This
prevents the switch from broadcasting the traffic to all ports and possibly disrupting network
performance.
If multicast routing is not supported on other switches in your network, you can use IGMP
Snooping and IGMP Query to monitor IGMP service requests passing between multicast
clients and servers, and dynamically configure the switch ports which need to forward
multicast traffic.
Multicast routers use information from IGMP snooping and query reports, along with a
multicast routing protocol such as DVMRP or PIM, to support IP multicasting across the
Internet.
