Setting The Maximum Number Of Igmp Groups - Cisco Catalyst 3750 Software Configuration Manual

Chapter 17 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 1 configure terminal
Step 2 interface interface-id
Step 3 ip igmp max-groups number
Step 4 end
Step 5
show running-config interface
interface-id
Step 6
copy running-config startup-config

Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the physical interface to
configure. The interface must be a Layer 2 port that does not belong to
an EtherChannel port group.
Apply the specified IGMP profile to the interface. The profile number
can be from 1 to 4294967295.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the physical interface to

Set the maximum number of IGMP groups that the interface can join.
The range is from 0 to 4294967294. The default is to have no maximum
set.
Return to privileged EXEC mode.
