Alarm Configuration
3-8 Basic Alarm Configuration
6. Click in the Rising Threshold field; enter the high 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 rising threshold of 1250 octets, enter a threshold value of
10.
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, on page 3-28.
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, on page 3-28.
10. Click the Apply button 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 the Apply button again.
Once you click the Apply button, 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.
TIP
Remember, the Actions Þelds will be grayed out for devices conÞgured to operate in
SecureFast switching mode, as there is no active bridging component on those interfaces.
