This read-create INTEGER lets a manager add, delete, or modify a VISM port row, where add(1) only succeeds if the current status is del, del(2) requires first removing all connections and the resource partition, and mod(3) changes the status to reflect a modification in progress. An admin cares because this row-management workflow enforces an order of operations, preventing a port from being deleted while it still has active connections or partitions. For example, a technician decommissioning a port must first clear all connections and the resource partition, then set this object to del(2) to actually remove the port.
