Report Suppression Interval
Supermicro switches forward the IGMP member reports sent by the hosts to IGMP multicast routers. To
avoid forwarding duplicate reports, Supermicro switches suppress any reports received within a short
time period for the same group. This time period is called the report suppression interval. Any reports
received for the same group after this interval passes will be forwarded to multicast routers.
Supermicro switches suppress IGMP reports for IGMP versions 1 and 2 only. If an IGMP
report contains IGMP version 3 reports, switches will forward these reports to multicast
routers without suppressing.
Users can configure the report suppression time period. The default value is 5 seconds.
Follow the steps below to configure the report suppression interval.
