no ip igmp snooping report-suppression
Parameters
None.
Default
By default, this option is disabled.
Command Mode

Command Default Level
Level: 12.
Usage Guideline
This command is only available for VLAN interface configuration. The report suppression function only
works for IGMPv1 and IGMPv2 traffic. When report suppression is enabled, the Switch suppresses
the duplicate reports sent by hosts. The suppression for the same group report or leave will continue
until the suppression time expired. For report or leave messages to the same group, only one report
or leave message is forwarded. The remaining report and leave messages are suppressed.
Example
This example shows how to enable report suppression on VLAN 1.
Switch# configure terminal
Switch(config)# vlan 1
Switch(config-vlan)# ip igmp snooping report-suppression
Switch(config-vlan)#
