14.3 Alarm Information
Note When an entity is put in the Locked,maintenance administrative state, the ONS 15454 SDH suppresses
all standing alarms on that entity. All alarms and events appear on the Conditions tab. You can change
this behavior for the LPBKFACILITY and LPBKTERMINAL alarms. To display these alarms on the
Alarms tab, set the NODE.general.ReportLoopbackConditionsOnPortsInLocked,Maintenance to TRUE
on the NE Defaults tab.
Table 14-2 lists the color codes for alarm and condition severities. The inherited (I) and unset (U)
severities are only listed in the network view Provisioning > Alarm Profiles tab.
Path Width Indicates how many VC-4s are contained in an alarmed path. (For any non-VC-4 object,
such as a VC-3, the column is blank.) This information complements the alarm object
notation, which is explained in Table 14-3.
Sev Severity level: CR (Critical), MJ (Major), MN (Minor), NA (Not Alarmed), NR
(Not Reported).
ST Status: R (raised), C (clear), T (transient).
SA When checked, indicates a service-affecting alarm.
Cond The error message/alarm name. These names are alphabetically defined in the “Alarm
Troubleshooting” chapter of the Cisco ONS 15454 SDH Troubleshooting Guide.
