Defining a Startup Alarm
A startup alarm allows the CSS to generate an alarm when the first sample triggers
a falling threshold or rising threshold (default).
• A startup falling alarm occurs when the first sample is less than or equal to
the falling threshold. To enable this alarm, enter:
(config-rmonalarm[1])# startup-type falling
• A startup rising alarm occurs when the first sample is greater than or equal to
the rising threshold. To enable this alarm, enter:
(config-rmonalarm[1])# startup-type rising
• To enable an alarm when either a falling or rising threshold is triggered, enter:
(config-rmonalarm[1])# startup-type rising-and-falling
To reset the startup alarm to a rising threshold alarm, enter:
(config-rmonalarm[1])# no startup-type
Defining the Sampling Interval
The sampling interval is the time interval, in seconds, over which the data is
sampled and compared with the rising and falling thresholds. Use the
sample-interval interval command to specify the sampling interval for the
RMON alarm. The interval variable is the number of seconds from 1 to 65535.
The default is 300 seconds.
To enter a sampling interval of 60 seconds, enter:
(config-rmonalarm[1])# sample-interval 60
With delta sampling, set the sampling interval short enough so the sampled
variable, which has a tendency to go up and down very fast, does not wrap during
a single sampling period.
To reset the sample interval to 300, enter:
(config-rmonalarm[1])# no sample-interval
