Basic Alarm Configuration
Trap
Indicates whether or not each alarm has been configured to issue a trap in
response to a rising or falling alarm condition: Yes if it has, No if it hasn’t.
Remember, if you choose to select this option for your alarms, you must be sure
the 7C0x has been configured to send traps to your management workstation, and
that the management workstation you choose has the ability to accept those trap
messages. See the Trap Table chapter in the SPMA Tools Guide for more
information.
Polling Interval
Displays the amount of time, in seconds, over which the selected alarm variable
will be sampled. At the end of the interval, the sample value will be compared to
both the rising and falling thresholds (described below). You can set any interval
from 1 to 999,999,999 seconds; however, intervals shorter than 10 seconds are not
likely to perform well. The default value is 30 seconds.
Rising Threshold
Displays the high threshold value set for the selected alarm variable. By default,
values used to compare to the thresholds are 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.
Rising Action
Indicates whether or not a rising alarm occurrence will initiate any actions in
response to the alarm condition: Enable if bridging will be enabled at the selected
interface in response to a rising alarm, Disable if bridging will be disabled at the
selected interface in response to a rising alarm, and None if no actions have been
configured for the selected alarm.
Falling Threshold
Displays the low threshold value set for the selected alarm variable. By default,
values used to compare to the thresholds are 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.
Falling Action
Indicates whether or not a falling alarm occurrence will initiate any actions in
response to the alarm condition: Enable if bridging will be enabled at the selected
interface in response to a falling alarm, Disable if bridging will be disabled in
response to a falling alarm, and None if no actions have been configured for the
selected alarm.
TIP
Current versions of the Basic Alarm Configuration application do not provide a means for
viewing any alarm logs you choose to create; if you wish to use the Log option, you can
view the associated log via the MIBTree or any similar SNMP-based tool. See Viewing an
Alarm Log
, page 3-10 , for details.
