Chapter 17 Configuring IGMP Snooping and Filtering
Configuring IGMP Filtering
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 were to deny (the default), it would not appear in the
show ip igmp profile command output.
Switch# config t
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
permit
range 229.9.9.0 229.9.9.0
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 a profile to multiple interfaces, but each
interface can only have one profile applied to it.
Note You can apply IGMP profiles to Layer 2 ports only. You cannot apply IGMP profiles to routed ports (or
SVIs) or to ports that belong to an EtherChannel port group.
To apply an IGMP profile to a switch port, perform this task:
Step 6
Switch# show ip igmp profile
profile number
Verifies the profile configuration.
Step 7
Switch# copy running-config startup-config
(Optional) Saves your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# interface
interface-id
Enters interface configuration mode, and enter the physical
interface to configure, for example fastethernet2/3. The interface
must be a Layer 2 port that does not belong to an EtherChannel
port group.
Step 3
Switch(config-if)# ip igmp filter
profile
number
Applies the specified IGMP profile to the interface. The profile
number can be from 1 to 4,294,967,295.
Step 4
Switch(config-if)# end
Returns to privileged EXEC mode.
Step 5
Switch# show running configuration
interface
interface-id
Verifies the configuration.
Step 6
Switch# copy running-config startup-config
(Optional) Saves your entries in the configuration file.
