cmTrapMajorAlarmCount is a read-only integer reporting how many major-severity alarms are currently uncleared on the system. An administrator monitors this to prioritize significant but non-critical issues, checking it after confirming cmTrapCriticalAlarmCount is at zero. For example, a sustained non-zero cmTrapMajorAlarmCount would prompt the operator to review the alarm log even if no critical alarms are present, since major alarms often precede escalating problems.
