Parameters

Description
Use the igmp report-aggregation command to enable suppression on Layer 3
multicast IGMP report messages. On an IP-multicast-routing-enabled switch, the VLAN
interface receives only the first IGMP report message from a multicast group in a query
interval.
Use the undo igmp report-aggregation command to disable suppression on Layer 3
multicast IGMP report messages.
By default, suppression on IGMP report messages is disabled.
Note:
z You must enable IP multicast routing globally before configuring suppression on
IGMP report messages.
z If IP multicast routing is disabled globally, suppression on IGMP report messages is
disabled simultaneously.
