4.9.2.3 IGMP Filter / Throttling Port Configuration
Once you have configured IGMP profiles, you can assign them to interfaces on the Managed 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 also 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.
