Chapter 2 IGMP Snooping Configuration
Commands
2-11
Description
Use the igmp-snooping report-aggregation command to enable suppression on
Layer 2 multicast IGMP report messages. In an IGMP Snooping-enabled VLAN, only
one IGMP report message is sent to the upstream router port during an interval.
Use the undo igmp-snooping report-aggregation command to disable suppression
on Layer 2 multicast IGMP report messages.
By default, suppression on IGMP report messages is disabled.
Note:
z IGMP snooping must be enabled globally before the suppression on IGMP report
messages is enabled.
z If IGMP snooping is disabled globally, the suppression on IGMP report messages is
disabled simultaneously.
