IGMP report suppression is supported only when the multicast query has IGMPv1 and IGMPv2 reports. 
This feature is not supported when the query includes IGMPv3 reports.

IGMP report suppression is enabled by default. When it is enabled, the switch forwards only one IGMP 
report per multicast router query. When report suppression is disabled, all IGMP reports are forwarded 
to the multicast routers. 

Beginning in privileged EXEC mode, follow these steps to disable IGMP report suppression:

To re-enable IGMP report suppression, use the ip igmp snooping report-suppression global 
configuration command.

You can display IGMP snooping information for dynamically learned and statically configured router 
ports and VLAN interfaces. You can also display MAC address multicast entries for a VLAN configured 
for IGMP snooping.

Enter global configuration mode.

Disable IGMP report suppression.

Return to privileged EXEC mode.

Verify that IGMP report suppression is disabled.

(Optional) Save your entries in the configuration file.
