This Gauge32 reports the count of correctable memory parity errors recorded on the switch during this SystemStatsHist collection interval. An admin watches this counter because correctable parity errors, while automatically fixed by hardware, can be an early warning sign of failing memory that will eventually cause a more serious fault. For example, a steadily climbing correctable parity error count across successive SystemStatsHist samples would prompt an admin to schedule proactive hardware replacement before an uncorrectable error occurs.
