IGMP Snooping
IGMP snooping helps to 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.

Traffic Control
Traffic control prevents the switch bandwidth from flooding packets including
broadcast packets, multicast packets. The limit number is a threshold to limit
the total number of the checked type packets. For example, if broadcast and
multicast are enabled, the total traffic amount for those two types will not
exceed the limit value. Click
