Alarm Configuration

Basic Alarm Configuration

Falling Thresholds Work, 

8.

Click in the Falling Threshold field; enter the low threshold value for this 
alarm. Remember, compared values are always relative, or delta values (the 
difference between the value counted at the end of the current interval and 
the value counted at the end of the previous interval); be sure to set your 
thresholds accordingly.

Remember, too, when configuring a Kilobits alarm, SPECTRUM Element 
Manager converts octets into kilobits (units of 125 bytes, or octets) for you; for 
example, to set a falling threshold of 625 octets, enter a threshold value of 5.

9.

In the Falling Action field, click to select the action you want your device to 
take in response to a falling alarm: Enable Port, Disable Port, or None. Note 
that this action enables and disables only 

bridging at the specified port, and 

not the interface itself.

Falling Thresholds Work, 

10. Click 

 to set your changes. If you have made any errors in configuring 

alarm parameters (using an invalid rising or falling threshold, for example, or 
neglecting to supply a polling interval), either an error window with the 
appropriate message will appear, or a beep will sound and the cursor will blink 
in the field which contains the error. Correct the noted problem(s), and click 

 again.

Once you click 

, the conÞgured alarm parameters will be set for every 

selected interface, and the alarms will automatically be enabled; the list box 
display will also refresh to reßect these changes.

To conÞgure additional alarms, or alarms of a different type, select the 
appropriate alarm variable at the top of the window, highlight the appropriate 
interface(s), and repeat the procedures outlined above.

Using the 

 button at the bottom of the window actually performs two 

functions: it both disables the alarm and deletes the alarm entry (and its 
associated event and action entries) from device memory to help conserve device 
resources. In the list box display, the parameters for any ÒdisabledÓ alarm are 
automatically reset to their default values.
