igmp report-aggregation
View
System view
Parameter
None
Description
Use the igmp report-aggregation command to enable suppression on Layer 3
multicast IGMP report packets. On an IP-multicast-routing-enabled switch, the VLAN
interface receives only the first IGMP report packet from a multicast group in a query
interval.
Use the undo igmp-snooping report-aggregation command to disable suppression
on Layer 3 multicast IGMP report packets.
By default, suppression on IGMP report packets is disabled.
Note:
z You must enable IP multicast routing globally before configuring suppression on
IGMP report packets.
z If IP multicast routing is disabled globally, suppression on IGMP report packets is
disabled simultaneously.
Example
# Enable suppression on Layer 3 multicast IGMP report packets on the switch.
