Alarm Configuration
3-8 Basic Alarm Configuration
7. In the Rising Action field, click to select the action you want your device to
take in response to a rising 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.
For more information on how actions are triggered, see How Rising and
Falling Thresholds Work, page 3-27.
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.
For more information on how actions are triggered, see How Rising and
Falling Thresholds Work, page 3-27.
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 configured alarm parameters will be set for every
selected interface, and the alarms will automatically be enabled; the list box
display will also refresh to reflect these changes.
To configure 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.
TIP
Remember, the Actions fields will be grayed out for devices configured to operate in
SecureFast switching mode, as there is no active bridging component on those interfaces.
