This sets, in milliseconds, how long a configurable alarm condition on this port must remain clear before it is officially declared cleared. As the clearing counterpart to pportConfigAlarmSoakTime, this prevents a flickering, intermittently-recovering fault on this specific port from repeatedly toggling between alarmed and cleared states, requiring the condition to stay genuinely resolved for the full duration before the alarm is considered over. Setting this to 5000 ms on this port means even after the underlying fault appears to go away, the alarm stays declared for a full 5 seconds to confirm the recovery is stable before clearing.
