Severity LevelsSeverityIcon DescriptionAlarm – An Alarm is a "serviceable event". This means that attention bythe user or field service is required. Alarms are posted asynchronouslyto the screen and cannot be turned off. If the alarm denotes that a sys-tem error has occurred the customer and/or field representative willgenerally be directed to provide a "show support" capture of the switch.Critical event – An event that indicates a potential failure. Critical logmessages are events that warrant notice by the user. By default, theselog messages will be posted to the screen. Critical log messages do nothave alarm status as they require no immediate attention from a user orservice representative.Warning event – An event that indicates errors or other conditions thatmay require attention to maintain maximum performance. Warning mes-sages will not be posted to the screen unless the log is configured to doso. Warning messages are not disruptive and, therefore, do not meetthe criteria of Critical. The user need not be informed asynchronouslyNo icon Informative – An unclassified event that provides supporting informa-tion.NOTE: Events (Alarms, Critical, Warning, and Informative) generated bythe application are not saved on the switch. They are permanentlydiscarded when you close a SANsurfer Switch Manager session,but you can save these events to a file on the workstation beforeyou close SANsurfer Switch Manager and read it later with a texteditor or browser. Events generated by the switch are stored on switch, and will beretrieved when the application is restarted. Some alarms areconfigurable. Refer to ”Configuring Port Threshold Alarms” onpage 4-14.
