In the context of Cisco Catalyst 9800 Series Wireless Controllers, RADIUS profiling requires the correct AAA (Authentication, Authorization, and Accounting) configuration to collect and forward details about clients to a RADIUS server such as Cisco ISE (Identity Services Engine). The correct command in this scenario is “aaa accounting network acct_method start-stop group rad-group” which enables accounting of network services. This command starts gathering accounting information for all network-related service requests and sends start and stop records to the RADIUS server specified in the ‘rad-group’. This allows the controller to forward information about clients’ activities on the wireless network to Cisco ISE for profiling.
