Technology Review
AAA stands for authentication, authorization, and accounting. The AOS AAA subsystem currently supports
authentication. Authentication is the means by which a user is granted access to the device (router). For
instance, a username/password is authenticated before the user can use the CLI. VPN clients can also
verify username/password before getting access through the device.
There are several methods that can be used to authenticate a user:
NONE Instant access
LINE-PASSWORD Use the line password (telnet 0-4 or console 0-1)
ENABLE-PASSWORD Use the enable password
LOCAL-USERS Use the local-user database
GROUP Use a group of remote RADIUS servers
