Configuring IGMP Filtering
Applying IGMP Profiles
To control access as defined in an I GMP pro file, us e the ip igmp filter interface configuration command
to apply the profile to the appropriate interfaces. You can apply IGMP profiles to Layer 2 ports only;
you cannot apply IGMP profiles to routed ports or SVIs. You can apply a profile to multiple interfaces,
but each interface can only have one profile applied t o it.
Beginning in privileged EXEC mode, follow these steps to apply an IGMP profile to a switch port:
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 an int erf ac e a nd veri fy t he con fig ura tio n.
Switch # config t
Switch(config)# interface fastethernet0/12
Switch(config-if)# ip igmp filter 4
Switch(config-if)# end
Switch# show running-config interface fastethernet0/12

Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface interface-id Enter interface configuration mode, and enter the physical interface to
configure, for example fastethernet0/3. The interface must be a Layer
2 port.
Step3 ip igmp filter profile number Apply the specified IGMP profile to the interface. The profile number
can be from 1 to 4294967295.
Step4 end Return to privileged EXEC mode.
Step5 show running configuration interface
interface-id Verify the configuration.
Step6 copy running-config startup-config (Optional) Save your entries in the configuration file.
