Applying Igmp Profiles - Cisco Catalyst 2950 Software Configuration Manual

Configuring IGMP Filtering
Command
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 # configure terminal
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 ports only; you
cannot apply IGMP profiles to SVIs.You can apply a profile to multiple interfaces, but each interface can
only have 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 ip igmp filter profile number
Step 4 end
Step 5
show running configuration 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 an interface and verify the configuration.
Switch # configure terminal
Switch(config)# interface fastethernet0/12
Switch(config-if)# ip igmp filter 4
Switch(config-if)# end
Switch# show running-config interface fastethernet0/12
