Chapter 20 Configuring IGMP Snooping and MVR
Configuring IGMP Filtering and Throttling
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 interface and verify the configuration.
Switch(config)# interface fastethernet0/12
Switch(config-if)# ip igmp filter 4
Switch(config-if)# end
Switch# show running-config interface fastethernet0/12

interface FastEthernet0/12
no ip address
shutdown
snmp trap link-status
ip igmp max-groups 25
ip igmp filter 4
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
max-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 can use this command on a logical EtherChannel interface but cannot
use it on ports that belong to an EtherChannel port group.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
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 that does not belong to an EtherChannel port group.
Step 3
ip igmp filter profile number Apply the specified IGMP profile to the interface. The profile number
can be from 1 to 4294967295.
Step 4
end Return to privileged EXEC mode.
Step 5
show running configuration interface
interface-id
Verify the configuration.
Step 6
