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.

4.5.6

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
