AAA enables the security appliance to determine who the user is (authentication), what the user can do (authorization), and what the user did (accounting). Cisco Nexus Dashboard Data Broker uses Remote Authentication Dial-In User Service (RADIUS) or Terminal Access Controller Access-Control System Plus (TACACS+) to communicate with an AAA server.

AAA server supports remote authentication and authorization. To authenticate each user, Cisco Nexus Dashboard Data Broker uses both the login credentials and an attribute-value (AV) pair. An AV pair assigns the authorized role for the user as part of the user administration. After successful authentication, the Cisco AV pair is returned to Cisco Nexus Dashboard Data Broker for resource access authorization.
