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.
