3 Multicast Filtering Configuring IGMP Filtering and Throttling for Interfaces Once you have configured IGMP profiles, you can then assign them to interfaces on the switch. Also, you can set the IGMP throttling number to limit the number of multicast groups an interface can join at the same time. Command Usage • Only one profile can be assigned to an interface. • An IGMP profile or throttling setting can be applied to a trunk interface. When ports are configured as trunk members, the trunk uses the settings applied to the first port member in the trunk. • 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. Command Attributes • Profile - Selects an existing profile number to assign to an interface. • Max Multicast Groups - Sets the maximum number of multicast groups an interface can join at the same time. (Range: 0-256; Default: 256) • Current Multicast Groups - Displays the current number of multicast groups the interface has joined. • Throttling Action Mode - Sets the action to take when the maximum number of multicast groups for the interface has been exceeded. (Default: Deny) • deny - The new multicast group join report is dropped. • replace - The new multicast group replaces an existing group. • Throttling Status - Indicates if the throttling action has been implemented on the interface. (Options: True or False) • Trunk - Indicates if a port is a trunk member. 3-171
