IGMP

Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and reports sent
between network stations or devices and an IGMP router. IGMP is used for managing IP multicast groups. The Switch will
send IGMP query messages and get the IGMP response from hosts to "learn" the source port members of that multicast
address. When a multicast address is received and found on the IGMP address table, it will be multicast to those port
members.
