Configuring IGMP Filtering and Throttling
To delete a profile, use the no ip igmp profile profile number global configuration command.
To delete an IP multicast address or range of IP multicast addresses, use the no range ip multicast
address IGMP profile configuration command.
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 only to Layer 2 access
ports. 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
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 gigabitethernet0/2
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.
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.
Apply the specified IGMP profile to the interface. The range is 1 to
4294967295.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
