4.5.5 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 255 spaces, the IGMP snoop does not

work normally. The switch only allows 255-layer 2 multicast group.

multicast are enabled, the total traffic amount for those two types will not exceed
