Without IGMP snooping, a switch would have to flood multicast packets

out all of its ports, except the port on which it received the packet. Such

flooding of packets can negatively impact switch and network

performance.

The AT-8024, AT-8024GB, and AT-8026FC switches support both IGMP

Version 1 and Version 2. The switches maintain their multicast groups

through an adjustable time-out value, which controls how frequently

they expect to see reports from end nodes that want to remain members

of multicast groups, and by processing leave requests.

Note

By default, IGMP snooping is disabled on the switch.
