Information About AAA

AAA Security Services

The authentication, authorization, and accounting (AAA) features allows you to verify the identity of, grant
access to, and track the actions of users managing Cisco Nexus 5000 Series switches. The Cisco Nexus 5000
Series switches support Remote Access Dial-In User Service (RADIUS) or Terminal Access Controller Access
Control device Plus (TACACS+) protocols.
Based on the user ID and password combination that you provide, the Cisco Nexus 5000 Series switches
perform local authentication or authorization using the local database or remote authentication or authorization
using one or more AAA servers. A preshared secret key provides security for communication between the
switch and AAA servers. You can configure a common secret key for all AAA servers or for only a specific
AAA server.
