On a switch (or a Linux bridge), Multicast snooping sits at network layer 2.5 and is intended to alleviate the load by: snooping the network traffic; identifying the multicast channels that each switch port is subscribed to security reasons. it is a subscriber port and should only receive multicast data. The default, the flooding query count is 2. information for the commands used in this section, see the command reference As the name implies, this is done by listening to IGMP traffic between the router and hosts: When the host sends a membership report for a multicast group then the switch adds an entry in the CAM table for the interface that is connected to the host. sending out IGMP join and leave messages.
