AirDefense reports alarms and device information and traffic statistics every minute. To understand the data that appears in AirDefense, you must understand how AirDefense addresses system time versus the local GUI time, particularly in regard to alarms.
When an alarm occurs, AirDefense detects the alarm in system time, and records this time in its database. You can configure AirDefense system time by using the Command Line Interface (CLI) found in the Configuration menu.
However, when reporting the alarm to the GUI, AirDefense adjusts the report time to your local system time zone. It uses this time to report alarms in the Alarms tab, and it also reports other statistical data in this manner. The last updated time on each GUI screen (indicated by the time stamp) correlates to the local system where the browser is running. You configure the GUI time for your local system.
