Setting this object to clearLog (1) purges the node's Operator log; setting it to noClearLog (2) is a no-op that leaves the log intact. Since this is write-only, an admin uses it purely as an action trigger, typically after archiving the log contents elsewhere via cdx6500reptEvent entries, since once cleared those entries cannot be recovered from the device. For example, an operator might read out all current cdx6500reptEvent alarm text, save it to a ticket, then set this to clearLog(1) to reset the log before the next maintenance window.
