This section explains RADIUS for Cisco NCS 1010. Use it to understand the feature behavior, requirements, and setup context before you configure or verify AAA, RADIUS, and TACACS+ configuration.
Remote Authentication Dial-In User Service (RADIUS) is a distributed client/server system that provides security against unauthorized access in distributed client/server networks. In Cisco's implementation, RADIUS clients operate on Cisco NCS 1010 and send requests for authentication and accounting to a central RADIUS server that contains all user authentication and network service access information.
Details
Cisco's AAA security paradigm supports RADIUS, which can be used alongside other security protocols like TACACS+, Kerberos, and local username lookup.
