| 4.2 |  | Network Access Server (NAS) AAA Authentication Process |
| 4.2.3 |  | NAS configuration |

| There are several tasks involved in the configuration of the NAS. These tasks are listed in Figure and in the demonstration activity.

| Lab Activity Lab Exercise: Configure AAA on Cisco Router In this exercise, students will protect the network access server (NAS), or pod router, by securing access using simple passwords without AAA. Students will then configure the NAS to perform AAA authentication functions against the local security database of the server.

| Media Activity Demonstration Activity: Configuring AAA for Cisco Perimeter Routers This activity describes how to configure a Cisco perimeter router to perform AAA using a local database.
