3-8 Configuring an Alarm
5. If you have selected the Trap option in the Alarm field, the Community field
will become active; any value you enter here will be included in any trap
messages. Your trap utility may use this community name as a means of
filtering traps, or as a means of directing traps within the management
platform; if it does not, you need not enter a value into this field. A value of
“public” will be assigned by default.
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 an In Octets Kb alarm, SPMA converts
octets into kilobytes for you; for example, to set a rising threshold of 5000
octets, enter a threshold value of 5.
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 3-6.
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 an In Octets Kb alarm, SPMA converts
octets into kilobytes for you; for example, to set a falling threshold of 2000
octets, enter a threshold value of 2.
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 3-6.
10. Click to set your changes. If you have made any errors in
configuring alarm parameters (using an invalid rising or falling thresholds, for
example), an error window with the appropriate message will appear. 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.
