Alarm Configuration
3. In the Interval field, enter the amount of time, in days, hours, minutes, and
seconds, over which the selected variable will be sampled. At the end of the
interval, the sample value will be compared to both the rising and falling
thresholds. You can assign any time interval up to 24,855 days. If you set an
incorrect time value (e.g., you enter 75 minutes instead of 1 hour, 15 minutes)
you will receive an error message. Click OK and enter the correct time value.
4. In the Alarm field, click to select one or both of the following options:
a. Select Log if you wish to create a silent log of alarm occurrences.
b. Select Trap if you want your device to issue a trap in response to each
alarm occurrence.
5. Any value you enter in the Community field will be included in any trap
messages issued by your SmartSwitch 2000 in response to the alarm(s) you
are configuring; this value is also used to direct traps related to this alarm to
the appropriate management workstation(s):
a. If you enter a value in this field, traps related to the associated alarms
will only be sent to the network management stations in the device’s trap
table
which have been assigned the same community name
(and for
which traps have been enabled). Any IP addresses in the device’s trap
table which have
not
been assigned the same community string, or which
have been assigned no community string, will not receive traps related to
the alarm(s) you are configuring.
b. If you leave this field blank, traps related to the associated alarms will
be sent to any network management stations which have been added to
the device’s trap table, and for which traps have been enabled —
regardless of whether or not those IP addresses have been assigned a
community name in the Trap Table.
NOTES
In order for the trap selection to work properly, your SmartSwitch 2000 must be
conÞgured to send traps to your network management station. This is accomplished via
Local Management and the Trap Table; consult your device hardware manual for more
information.
If you are monitoring a variable you consider to be critical, we do not recommend that you
select Trap as the only event response; if a trap is lost due to a collision or other
transmission problem, it will not be re-sent.
TIP
For more information about conÞguring the SmartSwitch 2000Õs Trap Table, consult your
Local Management documentation. (Remember, no traps will be sent by your
SmartSwitch 2000 at all unless its Trap Table has been properly conÞgured!)
