Configuring IGMP Filtering and Throttling
This example shows how to create IGMP profile 4 allowing access to the single IP multicast address and
how to verify the configuration. If the action was to deny (the default), it would not appear in the show
ip igmp profile output display.
Switch(config)# ip igmp profile 4
Switch(config-igmp-profile)# permit
Switch(config-igmp-profile)# range 229.9.9.0
Switch(config-igmp-profile)# end
Switch# show ip igmp profile 4
IGMP Profile 4
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 to layer 2 access ports
only; 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 only have one profile applied to it.
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 filter profile number
Step 4
end
Step 5
show running-config interface
interface-id
Step 6
copy running-config startup-config
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

permit
range 229.9.9.0 229.9.9.0
Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the physical interface to
configure. The interface must be a Layer 2 port that does not belong to
an EtherChannel port group.
Apply the specified IGMP profile to the interface. The profile number
can be from 1 to 4294967295.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
