Manage RADIUS Servers and Groups
Secure Access integrates with Cisco Identity Services Engine (ISE) to support the use of centralized RADIUS servers that provide authentication, authorization, and accounting services (AAA) for remote users who access a network. Authentication identifies the user. Authorization implements policies that determine which resources and services an authenticated user may access. Accounting keeps track of time and data resources that are used for billing and analysis.
If you want to use an external RADIUS server for authentication, authorization, or accounting, you must first create at least one RADIUS server group and add one or more servers to each group. You identify RADIUS server groups by name. Each server in a group is identified by a server name, IP address, and a shared key. When identifying RADIUS servers, the server group order (and server order within the group), determines the server access order.
