Operating Basics
The Alarm Con fi guration dialog allows you to perform the tasks listed below.
After you make any desired changes, click Apply to apply the changes and
then click OK to save the changes and close the dialog window.
Enable/disable tests. Click the box next to the test names to enable or
disable tests. Enabled tests are indicated by a check mark. Disabled tests
are indicated by a gray LED in the Metrics pane.
Set the Active threshold. Click in the Value fi eld and enter the
measurement threshold for each test. When this threshold is exceeded,
an error message will be generated. The Min/Max Value columns
list the threshold ranges for each test. The Nominal column lists the
recommended value for the test.
NOTE.
When there is a change in the Alarm state, for example, when the
measurement value crosses the Active threshold or when it crosses the Clear
threshold, SNMP traps are generated and sent to the Aggregator and to the
secondary trap destination intended for your NMS System (if you used the
Device Setup utility to con
fi gure the secondary trap destination).
Set the Clear threshold. Click in the Value fi eld and enter the measurement
threshold for each test. When this threshold is crossed by a test that is in
an active error condition, an error-cleared message will be generated.
Set the Severity level. Set the error-reporting severity level for each test
by picking from the drop-down list: Critical, Info, or Warning. Color
codes are assigned to the status LEDs based on the severity levels that are
con
fi gured here. (See page 55, Error indicator color codes .)
Con fi gure the Delay pro fi le echo parameters. Enable or disable the Delay
Pro fi le Echo measurement to set parameters such as amplitude level and
distance for echo-related time distortions. If the echo distance is set to
User De
fi ned, you can set the distance limits for modes 1 ,2 and 3. Alarms
occur if the echo amplitude is higher than the Amplitude level you set
and if it is outside of the set region. If the echo distance mode is set to
Automatic, alarms are generated based on the Mode and Guard Interval.
NOTE.
The Delay Pro fi le alarm is a software alarm, unlike the other alarms
which are SNMP alarms. Therefore, alarms generated by the Delay Pro fi le
alarm will not be sent to the secondary trap destination that is intended for
your NMS System.
