Configuring IGMP Snooping and MVR
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 gigabitethernet1/0/1
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
mac-groups interface 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 cannot use this command on ports that belong to an EtherChannel port
group.
Beginning in privileged EXEC mode, follow these steps to apply an IGMP profile to a switch port:
Command

Step 3
ip igmp max-groups number
Step 4
end
Step 5
show running-config interface
interface-id
Step 6
