Chapter 24 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 a port:
Switch(config)# interface gigabitethernet1/0/2
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
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.
Beginning in privileged EXEC mode, follow these steps to set the maximum number of IGMP groups in
the forwarding table:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id 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.
Step 3 ip igmp filter profile number Apply the specified IGMP profile to the interface. The range is 1 to
4294967295.
Step 4
end Return to privileged EXEC mode.
Step 5 show running-config interface
interface-id
Verify the configuration.
Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify the interface to be configured, and enter interface configuration
mode. The interface can be a Layer 2 port that does not belong to an
EtherChannel group or a EtherChannel interface.
Step 3 ip igmp max-groups number Set the maximum number of IGMP groups that the interface can join.
The range is 0 to 4294967294. The default is to have no maximum set.
Step 4
end Return to privileged EXEC mode.
Step 5
show running-config interface
interface-id
Verify the configuration.
Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.
