WebMar 12, 2016 · Discovering multicast sources needs to be done in different way, either by utilizing NetFlow, or by monitoring the traffic on SPAN ports or directly at end hosts. Please be aware that a multicast group can exist without any source sending data into it. WebIGMP snooping is a protocol that learns and maintains multicast group membership at the Layer 2 level. IGMP snooping looks at IGMP traffic to decide which ports should be allowed to receive multicast traffic from certain sources and for certain groups. This information is used to forward multicast traffic to only interested ports.
