Applying Igmp Profiles; Setting The Maximum Number Of Igmp Groups - Cisco ME 3400 Software Configuration Manual

Configuring IGMP Filtering and Throttling

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 IGMP profiles to routed ports or SVIs. 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 no shutdown
Step 4 ip igmp filter profile number
Step 5 end
Step 6 show running-config interface
interface-id
Step 7 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

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 can use this command on a logical EtherChannel interface but cannot use
it on ports that belong to an EtherChannel port group.

21-26
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.
Enable the port, if necessary. By default, UNIs and ENIs are disabled,
and NNIs are enabled.
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.
