Introduces RADIUS realms for authentication and accounting, providing instructions to enable realms on WLANs, configure realm matching and AAA policies, and verify RADIUS-realm configurations for robust user access management. Details RADIUS accounting for AP events by guiding configuration of accounting method lists for AP profiles, verification of AP accounting data, and setup of AAA and HTTP command accounting using named method lists via CLI. Explains the use and configuration of RADIUS call station identifiers, offering procedures to properly set up these identifiers for enhanced tracking and management of authentication sessions. Describes the deployment of RADIUS Vendor-Specific Attributes, guiding creation of attribute lists and mapping AAA policies to WLAN policy profiles and WLANs for flexible and granular network authentication controls.
