RuggedSwitch™ User Guide
Active alarms are removed (cleared) either by solving the original cause of the
alarm or by disabling the alarm itself.
Passive Alarms
Passive alarms are historic in nature. They signify events that represented
abnormal conditions in the past, and do not affect the current operational status.
Examples of passive alarms include authentication failures or error rates that
temporarily exceeded a certain threshold.
Passive alarms are cleared through the diagnostics menu Clear Alarms command.
RMON generated alarms are passive.
Note:
Alarms are volatile in nature. All alarms (active and passive) are cleared at startup.
Format of Alarms
Every alarm includes the following information:
• The time of the alarm occurrence
• The alarm level
• The alarm description
Alarm Time
The alarm time provides the month, hour and minute at which the alarm occurred.
Note:
If the hardware is not equipped with a real time clock the SNTP feature must be
configured in order to obtain the time of day used in alarms. SNTP will typically obtain the
correct real time via the network within seconds after startup. Alarms occurring before SNTP
obtains the time will be displayed relative to midnight of January 1rst.
Alarm Level
The alarm level provides an indication of the severity of the alarm. The possible
levels correspond to those described in the UNIX SysLog facility.
