Usage Guidelines
DAI allows an RU to detect the ARP Request and Reply packets transmitted on the VAPs of the RU, to discard invalid and attack ARP packets, and to send an alarm to the connected Central AP. This function prevents ARP packets of unauthorized users from accessing the external network through the RU, protecting authorized users against interference or spoofing, and protecting the RU.
- Invalid ARP packets: The source IP and MAC addresses of ARP Request and Reply packets do not match.
- Attack ARP packets: When an RU receives a large number of consecutive ARP packets and the number of ARP packets exceeds the ARP attack alarm threshold, an ARP attack occurs.
