Usage Guidelines

Usage Scenario

After DAI is enabled, if you want to receive an alarm when a large number of ARP packets are discarded by DAI, you can run the arp anti-attack check user-bind alarm enable command. After the alarm function is enabled, the device sends an alarm when the number of discarded ARP packets exceeds the threshold.

The alarm threshold is set by the arp anti-attack check user-bind alarm threshold command.

Prerequisites

DAI has been enabled on the interface using the arp anti-attack check user-bind enable command.
