IGMP Snooping Table
By supporting IGMP (Internet Group Management Protocol) Snooping, the switch can forward
multicast traffic intelligently. Packets are only forwarded to the ports that belong to the
multicast group instead of being broadcast to all ports and possibly disrupting network
performance.
Figure 29. The IGMP Snooping Table
This lookup table lists each of the multicast groups present in the switch and shows the
associated port map. Up to 32 multicast groups are supported.
