General AAA Configuration
The AAA component consists of AAA profiles and AAA methods. A service (e.g. Telnet) has to specify a profile it
wants to apply to all login requests. The profile then specifies the sequence in which methods are applied to obtain
AAA information. Figure 15 illustrates the correlation between the Telnet login and console login services.
Figure 15. How to use AAA methods and AAA profiles
The Telnet service uses an AAA profile called cli-login. This profile specifies that the following methods are used
in the order they appear in the configuration:
1. Query RADIUS server radius_deepblue.
2. Query RADIUS server radius_extern.
