IGMP Snooping
Use this section to create an IGMP Snooping Profile. Internet Group Management Protocol
(IGMP) Snooping is a feature that allows a switch to forward multicast traffic intelligently on
the switch. Multicast IP traffic is traffic that is destined to a host group. Host groups are
identified by class D IP addresses, which ranges from 224.0.0.0 to 239.255.255.255. Based on
the IGMP query and report messages, the switch forwards traffic only to the ports that
request the multicast traffic. This prevents the switch from broadcasting the traffic to all ports
and possibly affecting network performance.
To view the IGMP Snooping menu, navigate to IGMP Snooping.
