Global Level, you define 2 commands
(config)# ip igmp filter
(config)# ip igmp profile <profile number>
Interface Level, you apply the filter to the respective interface
(config-if)# ip igmp filter <profile number>
-- Globally disable ip igmp filter will disable all applied interface
igmp filters --
(config)#no ip igmp filter
% Warning: all the existing IGMP filters are now disabled
Rack1SW2(config)#ip igmp ?
filter IGMP Filter Enable
immediate-leave Leave groups immediately without sending last member query,
use for one host network only
limit IGMP limit
profile IGMP Filter Profile
snooping Global IGMP Snooping enable for Catalyst Vlans
ssm-map SSM mapping commands
vrf Select VPN Routing/Forwarding instance
Use the ip igmp filter interface configuration command to control
whether or not all hosts on a Layer 2 interface can join one or more
IP multicast groups by applying an Internet Group Management Protocol
(IGMP) profile to the interface. Use the no form of this command to
remove the specified profile from the interface.
Rack1SW2(config-if)#ip igmp filter ?
<1-4294967295> IGMP profile number
