4.7.6 IGMP Snooping
Enable the IGMP snooping will let the switch learn the multicast router port and
group address member ports into the multicast address table. The table is
combined with L2 MAC table, so the maximum entry is 8K. The valid port
member will auto aging out after about 5 minute idle. See figures below.
