Configuring an RMON Alarm Chapter 6 Configuring Remote Monitoring (RMON) 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 6-20 Cisco Content Services Switch Administration Guide OL-5647-02
