4.6.5 IGMP Snooping
IGMP snooping helps reduce the multicast traffics on the network by
allowing the IGMP snooping function to be turned on or off. When turned
on, the switch snoops the IGMP packets and puts the new group into the
multicast table. However, if the static entries occupy all 256 spaces, the
IGMP snoop does not work normally. The switch only allows 256-layer 2
multicast group.
