SET RMON ALARM
SET RMON ALARM
Use the SET RMON ALARM command to set up an alarm that triggers an event
based on the parameters you specify.
Each sample is compared against two thresholds, a rising threshold and a falling
threshold. Each sample can be either an absolute value or a delta value (the
difference between the current value and the value of the previous sample). If
the value crosses the threshold, an event associated with that threshold may be
generated. The threshold is not rearmed until the opposite threshold is crossed
(rising or falling). This prevents the generation of multiple events as a sample
crosses just above and below a specific threshold.

instance The specific instance for the selected statistics type.
rising
Introduces the parameters for the rising threshold.
falling
Introduces the parameters for the falling threshold.
threshold The statistic value falling below the threshold triggers the event.
event index Index number of the RMON event triggered by the rising or falling threshold. Use the
SET RMON EVENT command to create events, and the SHOW RMON EVENTS
command to view event index numbers.
time Time between samples in hh:mm format.
rising_start
Specifies that the first event must be triggered by the rising threshold.
falling_start
Specifies that the first event must be triggered by the falling threshold.
any_start
Specifies that the first event can be triggered by the rising threshold or falling
threshold.
delta_type
Specifies that the threshold value is compared to the change in the statistic value
since the last sample.
absolute_type
Specifies that the threshold value is compared to the absolute statistic value.
