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.
