Chapter 21 Configuring IGMP Snooping and MVR Configuring IGMP Filtering and Throttling • permit: Specifies that matching addresses are permitted. • range: Specifies a range of IP addresses for the profile. You can enter a single IP address or a range with a start and an end address. 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: Step 1 Step 2 Command configure terminal ip igmp profile profile number Step 3 permit | deny Step 4 range ip multicast address Step 5 Step 6 Step 7 end show ip igmp profile profile number copy running-config startup-config 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. 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 78-11380-10 Catalyst 2950 and Catalyst 2955 Switch Software Configuration Guide 21-23
