This object is a read-create RowStatus controlling creation and deletion of rows that associate a user-facing port with an LST group; a manager sets it to createAndGo(4) to add the association and to destroy(6) to remove it, while a query on this object always returns 1. Administrators use it to bind specific downstream user ports, indexed by LST group index and ifIndex, so their link status is tied to the group's uplink failover decisions. For example, an NMS would set this to createAndGo(4) to enroll a subscriber-facing port into LST group 2's controlled set.
