A read-create RowStatus controlling creation and deletion of a static multicast group-join entry for a port, supporting active, notReady, createAndGo, and destroy states. A newly created row stays in notReady until the port actually belongs to the relevant VLAN and IGMP or IGMP snooping is enabled on that VLAN, so this object reflects whether the static join is actually operational, not just configured. An admin who creates a row with createAndGo but sees it stuck at notReady should check that the port has been added to the multicast VLAN and that IGMP snooping is enabled there.
