Applying Igmp Profiles - Cisco Catalyst 3750 Software Configuration Manual

Configuring IGMP Filtering
The default is for the switch to have no IGMP profiles configured. When a profile is configured, if
neither the permit nor deny keyword is included, the default is to deny access to the range of IP
addresses.
Beginning in privileged EXEC mode, follow these steps to create an IGMP profile:
Command
Step 1 configure terminal
Step 2
ip igmp profile profile number
Step 3
permit | deny
Step 4
range ip multicast address
Step 5
end
Step 6
show ip igmp profile profile number
Step 7 copy running-config startup-config
To delete a profile, use the no ip igmp profile profile number global configuration command.
To delete an IP multicast address or range of IP multicast addresses, use the no range ip multicast
address IGMP profile configuration command.
This example shows how to create IGMP profile 4 allowing access to the single IP multicast address and
how to verify the configuration. If the action was to deny (the default), it would not appear in the show
ip igmp profile output display.
Switch(config)# ip igmp profile 4
Switch(config-igmp-profile)# permit
Switch(config-igmp-profile)# range 229.9.9.0
Switch(config-igmp-profile)# end
Switch# show ip igmp profile 4
IGMP Profile 4

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 to layer 2 access ports
only; 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 only have one profile applied to it.

permit
range 229.9.9.0 229.9.9.0
Purpose
Enter global configuration mode.
Enter IGMP profile configuration mode, and assign a number to the
profile you are configuring. The range is from 1 to 4294967295.
(Optional) Set the action to permit or deny access to the IP multicast
address. If no action is configured, the default for the profile is to deny
access.
Enter the IP multicast address or range of IP multicast addresses to
which access is being controlled. If entering a range, enter the low IP
multicast address, a space, and the high IP multicast address.
You can use the range command multiple times to enter multiple
addresses or ranges of addresses.
Return to privileged EXEC mode.
Verify the profile configuration.
(Optional) Save your entries in the configuration file.
