Applying IGMP Profiles

To control access as defined in an IGMP profile, use the ip igmp filter interface configuration command to apply the profile to the appropriate interfaces. You can apply IGMP profiles only to Layer 2 access ports; you cannot apply IGMP profiles to routed ports or SVIs. You cannot apply profiles to ports that belong to an EtherChannel port group. You can apply a profile to multiple interfaces, but each interface can have only one profile applied to it.

Beginning in privileged EXEC mode, follow these steps to apply an IGMP profile to a switch port:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface interface-id	Specify the physical interface, and enter interface configuration mode.
		The interface must be a Layer 2 port that does not belong to an
		EtherChannel port group.
Step 3
	ip igmp filter profile number	Apply the specified IGMP profile to the interface. The range is 1 to
		4294967295.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	show running-config interface	Verify the configuration.
	interface-id
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To remove a profile from an interface, use the no ip igmp filter profile number interface configuration command.

This example shows how to apply IGMP profile 4 to a port:

Switch(config)# interface gigabitethernet1/0/2

Switch(config-if)# ip igmp filter 4

Switch(config-if)# end

Setting the Maximum Number of IGMP Groups

You can set the maximum number of IGMP groups that a Layer 2 interface can join by using the ip igmp max-groupsinterface configuration command. Use the no form of this command to set the maximum back to the default, which is no limit.

This restriction can be applied to Layer 2 ports only; you cannot set a maximum number of IGMP groups on routed ports or SVIs. You also can use this command on a logical EtherChannel interface but cannot use it on ports that belong to an EtherChannel port group.
