Alarm Configuration

3-6 Basic Alarm Configuration

The remainder of the window fields provide the means for configuring alarms for
each available interface. The information provided in this screen is static once it is
displayed; for updated information, click on the Refresh button. Adding or
modifying an alarm automatically updates the list.
Creating and Editing a Basic Alarm
The editable fields at the bottom of the Basic Alarm Configuration window allow
you to configure alarm parameters for each available interface. These fields will
display the parameters used for the most recently configured alarm (no matter
which interfaces are selected in the list box); this allows you to set the same
parameters on multiple interfaces with a single set. Hold down the Shift key
while clicking to select a contiguous group of interfaces; use the Ctrl key to select
any interfaces. To display the alarm parameters for a specific interface,
double-click on that interface.
There is no specific “Enable” function; simply configuring thresholds and/or
actions for an alarm and applying those changes enables the alarm. For more
information on disabling an alarm, see Disabling a Basic Alarm, on page 3-8.
To configure an alarm:
1. At the top of the window, click to select the variable to be used for your alarm:
Kilobits, Total Errors, or Broadcast/Multicast. The display in the list box will
reflect the current status at each interface of the alarm type you have
selected.
2. In the list box, click to highlight the interface (or use shift-click or ctrl-click to
select multiple interfaces) for which you would like to configure an alarm for
the selected variable. Note that the editable fields will display the parameters
assigned to the most recently set alarm; however, any changes you make in
these fields will be set to

all

selected interfaces.
3. In the Interval field, enter the amount of time, in days, hours, minutes, and
seconds, over which the selected variable will be sampled. At the end of the
interval, the sample value will be compared to both the rising and falling
thresholds. You can assign any time interval up to 24,855 days. If you set an
incorrect time value (e.g., you enter 75 minutes instead of 1 hour, 15 minutes)
you will receive an error message. Click OK and enter the correct time value.
4. In the Alarm field, click to select one or both of the following options:
a. Select Log if you wish to create a silent log of alarm occurrences.
b. Selec t Trap if you want your device to issue a trap in response to each
alarm occurrence.
