Clients with High 802.1X Authentication Failures

The Clients had excessive 802.1x authentication failures insight can be accessed from the Global, Site, Access Points, and Clients context. This insight provides information on excessive 802.1X802.1X is an IEEE standard for port-based network access control designed to enhance 802.11 WLAN security. 802.1X provides an authentication framework that allows a user to be authenticated by a central authority. authentication failures observed in the network. It is categorized under connectivity since the users are unable to connect to the WiFi network. This insight displays the following information:

• Insight Summary
• Time Series Graph
