set igmp report-suppression
Use this command to suppress the IGMP reports on a given VLAN ID. In order to optimize the number
of reports traversing the network with no added benefits, a Report Suppression mechanism is
implemented. When more than one client responds to an MGMD query for the same Multicast Group
address within the max-response-time, only the first response is forwarded to the query and others are
suppressed at the switch.
