Q

4 – Managing Switches Configuring Alarms

6.Enter a value for the rising threshold. A rising threshold alarm is generated when the event count exceeds the rising threshold. The switch will not generate another rising threshold alarm for that event until the count descends below the falling threshold and rises again above the rising threshold. Consider the example in Figure 4-8.

Note: The switch will down a port if a rising threshold alarm is not cleared after three consecutive sample intervals.

7.Enter a sample interval in seconds. The sample interval defines the period of time in which to count events.

8.Check the Enable box to make the alarm eligible for use. Repeat steps 3 through 8 for each alarm you want to configure or enable. You must also check the Enable All Alarm Thresholds box, which is the master control for all alarm configurations.
