Usage Guidelines

Usage Scenario

To allow the administrator to learn the ARP running status in real time, define potential attacks, and take measures, the device provides the alarm function for potential ARP attacks. This function records exceptions of ARP running in real time. To avoid excessive alarms when ARP attacks occur, reduce the alarm quantity by setting a proper interval for sending alarms.


In the insecure environment, you are advised to extend the interval for sending ARP alarms. This prevents excessive ARP alarms. In the secure environment, you are advised to shorten the interval for sending ARP alarms. This facilitates fault rectification in real time.

After the interval is set, the device discards alarms generates in this interval; therefore, some faults cannot be rectified in real time.


# Set the interval for sending ARP alarms to 20 seconds.
