This write-only action object clears all of this Section's cumulative counters (LOS, LOF) when set to clear(2), leaving them unchanged when set to noAction(1). An admin cares because these are long-running lifetime-style counters rather than interval-bound ones, so this is the only way to reset them back to zero, typically done after a physical repair to establish a clean baseline going forward. For example, after replacing a suspect fiber patch cord that had accumulated LOS events, an admin would set this to clear(2) to confirm the counter stays at zero afterward, proving the fix held.
