The status of this row. An entry may not exist in the active state unless all objects in the entry have an appropriate value. No objects are required to be written prior to the row being set to active(1). However, all portSelTable entries which are to be included in collections on behalf of this portSelectGroup, must be completely configured and activated before this object is set to active(1), since the associated instances of portSelStatus cannot be modified once this object has been set to active(1). If this object is not equal to active(1), all associated data collections shall be deleted (e.g., any associated collections in the atmStats, atmHostTable or atmMatrixSDTable). Note that associated portSelTable and any configured collection control entries (e.g., atmHostControlTable) are not deleted when this entry leaves the active state.
