IGMP – Configuration, Continued...
If Remove Unused Groups is checked then unused IGMP Groups will be removed and traffic with those
multicast addresses will be treated as normal multicast. If unchecked, then unused IGMP Groups are not
removed and traffic with those multicast addresses will be limited. The default is checked. Note that IGMP
Groups are not retained through a power cycle.
