If the switch does not receive a response, the switch will retransmit the request at periodic intervals. The switch will initiate authentication by sending an EAP Request-Identity message to the endpoint. ![]() Session Initiationįrom the switch’s perspective, the authentication session begins when the switch detects link-up on a port. The below diagram illustrates the default behavior of a MAB-enabled port. ![]() A MAB-enabled port can be dynamically enabled or disabled based on the MAC address of the device that connects to it. MAB enables port-based access control using the MAC address of the endpoint. Throughout this article, we will look at how to monitor 802.1X EAP and why doing so is important from a network security perspective. The EAP protocol can be configured for credential (EAP-TTLS/PAP and PEAP-MSCHAPv2) and digital certificate (EAP-TLS) authentication and is a highly secure method for protecting the authentication process. ![]() 802.1x is the standard that is used for passing EAP over wired and wireless Local Area Networks (LAN), as it provides an encrypted EAP tunnel that prevents outside users from intercepting information. As we’ve written about previously, the standard authentication protocol used on encrypted networks is Extensible Authentication Protocol (EAP), which provides a secure method to send identifying information for network authentication.
