command to enable report suppression for IGMP version 1 and version 2. Report
suppression does not apply to IGMP version 3, and is turned off by default for IGMP
version 1 and IGMP version 2 reports. The switch uses IGMP report suppression to
forward only one IGMP report per multicast router query to multicast devices. When
