4 Multicast Filtering Commands IGMP Filtering and Throttling Commands In certain switch applications, the administrator may want to control the multicast services that are available to end users. For example, an IP/TV service based on a specific subscription plan. The IGMP filtering feature fulfills this requirement by restricting access to specified multicast services on a switch port, and IGMP throttling limits the number of simultaneous multicast groups a port can join. Table 4-71 IGMP Filtering and Throttling Commands Command Function Mode ip igmp filter Enables IGMP filtering and throttling on the switch GC ip igmp profile Sets a profile number and enters IGMP filter profile GC configuration mode permit, deny Sets a profile access mode to permit or deny IPC range Specifies one or a range of multicast addresses for a profile IPC ip igmp filter Assigns an IGMP filter profile to an interface IC ip igmp max-groups Specifies an IGMP throttling number for an interface IC ip igmp max-groups action Sets the IGMP throttling action for an interface IC show ip igmp filter Displays the IGMP filtering status PE show ip igmp profile Displays IGMP profiles and settings PE show ip igmp throttle Displays the IGMP throttling setting for interfaces PE interface Page 4-211 4-212 4-212 4-213 4-213 4-214 4-215 4-215 4-216 4-216 ip igmp filter (Global Configuration) This command globally enables IGMP filtering and throttling on the switch. Use the no form to disable the feature. Syntax [no] ip igmp filter Default Setting Disabled Command Mode Global Configuration Command Usage • IGMP filtering enables you to assign a profile to a switch port that specifies multicast groups that are permitted or denied on the port. An IGMP filter profile can contain one or more, or a range of multicast addresses; but only one profile can be assigned to a port. When enabled, IGMP join reports received on the port are checked against the filter profile. If a requested multicast group is permitted, the IGMP join report is forwarded as normal. If a requested multicast group is denied, the IGMP join report is dropped. • IGMP filtering and throttling only applies to dynamically learned multicast groups, it does not apply to statically configured groups. 4-211
