Configuring IGMP Filtering
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 Verify the profile configuration.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
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 command.
This example shows how to create IGMP profile 22 denying access to the single IP multicast address
and how to verify the configuration. Note that because the action was to deny (the default), it does not
appear in the show ip igmp profile profile number privileged EXEC command output.
Switch # config t
Switch(config) # ip igmp profile 22
Switch(config-igmp-profile)# deny
Switch(config-igmp-profile)# range 229.9.9.0
Switch(config-igmp-profile)# end
Switch# show ip igmp profile 22
