2.2.3 Configuring IGMP Snooping Parameters Globally
Configuring Report Message Suppression
Step 1
configure
Enter global configuration mode.
Step 2
ip igmp snooping report-suppression
Enable Report Message Suppression globally. If this function is enabled, the switch will only
forward the first IGMP report message to Layer 3 devices and suppress subsequent IGMP
report messages from the same multicast group during one query interval, which reduces the
number of IGMP packets.
Step 3
end
Return to privileged EXEC mode.
Step 4
show ip igmp snooping
Show the basic IGMP snooping configuration.
Step 5
copy running-config startup-config
Save the settings in the configuration file.
