Setting the Maximum Number of IGMP Groups

You can set the maximum number of IGMP groups that an interface can join. Use the no form of this
command to set the maximum back to the default, which is no limit.
Beginning in privileged EXEC mode, follow these steps to apply an IGMP profile to a switch port:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
ip igmp max-groups number
Step 4
end
Step 5
show running-configuration interface
interface-id
Step 6
copy running-config startup-config
To remove the maximum group limitation and return to the default of no maximum, use the no ip igmp
max-groups interface configuration command.
This example shows how to limit the number of IGMP groups that an interface can join to 25.
Switch# configure terminal
Switch(config)# interface fastethernet0/12
Switch(config-if)# ip igmp max-groups 25
Switch(config-if)# end
Switch# show running-config interface fastethernet0/12
