3.10. IGMP Snooping Table
Figure 3-28. The IGMP Snooping Table
By supporting IGMP (Internet Group Management Protocol) Snooping, the switch can forward multicast traffic intelligently. Packets are forwarded to the ports that belong to the multicast group instead of being
broadcast to all ports and possibly disrupting network performance. This lookup table reflects the multicast group(s) (up to 32) configuration of your system and provides an overview of the port(s) map to each
multicast group.
