Chapter 17 Configuring IGMP Snooping and MVR
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 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
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 IGMP profiles to Layer 2 ports only.
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.
Beginning in privileged EXEC mode, follow these steps to apply an IGMP profile to a switch port:
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(config)# interface fastethernet0/12
Switch(config-if)# ip igmp filter 4
Switch(config-if)# end
Switch# show running-config interface fastethernet0/12
Building configuration...
Step 6
show ip igmp profile profile number Verify the profile configuration.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Enter interface configuration mode, and enter the physical interface to
configure, for example fastethernet0/3. The interface must be a Layer
2 port that does not belong to an EtherChannel port group.
Step 3
ip igmp filter profile number Apply the specified IGMP profile to the interface. The profile number
can be from 1 to 4294967295.
Step 4
end Return to privileged EXEC mode.
Step 5
show running configuration interface
interface-id
Verify the configuration.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
