Alarm
In this chapter, the Administrator can view traffic alarms and event alarms that occur and the
Bandwidth Manager has logged.
Bandwidth Manager has two alarms: Traffic Alarm and Event Alarm.
Traffic alarm:
In control policies, the Administrator set the threshold value for traffic alarm. The System
regularly checks whether the traffic for a policy exceeds its threshold value and adds a record
to the traffic alarm file if it does.
Event alarm:
When Bandwidth Manager detects attacks from hackers, it writes attacking data in the event
alarm file and sends an e-mail alert to the Administrator to take emergency steps
.
Blaster Alarm: When the Ovislink RS2000 had detected the internal PC sending
large DDos attacks and then the Blaster Alarm will start on blocking these packets to
maintain the whole network.
