What Is Dynamic ARP Inspection (DAI)? Dynamic Address Resolution Protocol Inspection (DAI) is an essential security feature that plays a vital role in network protection. In this informative video, we will outline the key functions of DAI and how it helps prevent attacks that can disrupt network communication. We will discuss the importance of ARP in connecting devices and the vulnerabilities that come with it, particularly the risks posed by false ARP messages.

You'll learn how DAI inspects ARP packets on untrusted interfaces and utilizes a trusted database created through DHCP snooping to verify packet information. We'll explain the significance of DHCP snooping and how it assists DAI in maintaining network integrity. Additionally, we will touch on the role of ARP access lists and how they enable precise control over which packets are accepted or denied.

Furthermore, we will examine the interface trust state and the logging and rate-limiting features of DAI, highlighting their importance in keeping networks secure and stable. Implementing DAI effectively requires careful configuration, and we will provide guidance on how to set up trust states and manage your trusted database.
