Alarms tab field descriptions
The following table describes the fields on the Alarms tab.
Name Description
Variable Specifies the Name and Type of alarm in one
of the following formats:
• alarm.x: where x=0 to indicate a chassis
alarm
• alarmname.: where you specify the index.
The index is a card number for module-
related alarms, OR an STG ID for spanning
tree group alarms (the default STG is 1,
other STG IDs are user-configured), OR
the Ether Statistics Control Index for
RMON Stats alarms.
• alarmname with no dot or index: is a
port-related alarm and results in the display
of the port selection tool.
Sample Type Specifies either absolute or delta
Interval Specifies the time period (in seconds) over
which the data is sampled and compared
with the rising and falling thresholds.
Index Uniquely identifies an entry in the alarm
table. Each entry defines a diagnostic
sample at a particular interval for an object
on the device.
Rising Threshold Specifies that when the current sampled
value is greater than or equal to this
threshold, and the value at the last sampling
interval was less than this threshold, the
alarm generates a single event.
RisingEventIndex Specifies the index of the event entry that is
used after a rising threshold is crossed. The
event entry identified by a particular value of
this index is the same as identified by the
same value of the event index object.
(Generally, accept the default that is already
entered.)
Falling Threshold Specifies that when the current sampled
value is less than or equal to this threshold,
and the value at the last sampling interval
