4 Command Line Interface Command Mode Interface Configuration Command Usage • The IGMP filtering profile must first be created with the ip igmp profile command before being able to assign it to an interface. • Only one profile can be assigned to an interface. • A profile can also be assigned to a trunk interface. When ports are configured as trunk members, the trunk uses the filtering profile assigned to the first port member in the trunk. Example Console(config)#interface ethernet 1/1 Console(config-if)#ip igmp filter 19 Console(config-if)# ip igmp max-groups This command sets the IGMP throttling number for an interface on the switch. Use the no form to restore the default setting. Syntax ip igmp max-groups number no ip igmp max-groups number - The maximum number of multicast groups an interface can join at the same time. (Range: 0-64) Default Setting 64 Command Mode Interface Configuration Command Usage • IGMP throttling sets a maximum number of multicast groups that a port can join at the same time. When the maximum number of groups is reached on a port, the switch can take one of two actions; either "deny" or "replace." If the action is set to deny, any new IGMP join reports will be dropped. If the action is set to replace, the switch randomly removes an existing group and replaces it with the new multicast group. • IGMP throttling can also be set on a trunk interface. When ports are configured as trunk members, the trunk uses the throttling settings of the first port member in the trunk. 4-214
