cmTrapEventLogType is a read-only enumeration classifying what kind of event a given event-log entry records, such as coldStart, boardDown, linkUp, or loginFailed. An administrator reads this to quickly triage the log, for instance filtering for loginFailed events to investigate repeated unauthorized access attempts. For example, seeing several loginsSaturated entries in a row would alert the operator to a possible brute-force attempt against the management interface.
