Configuring AAA
By configuring AAA, you can provide network access service for legal users, protect the networking
devices, and avoid unauthorized access and repudiation. In addition, you can configure ISP domains
to perform AAA on accessing users.
The AAA feature allows you to manage users based on their access types:
z LAN users: Users on a LAN who access through, for example, 802.1X authentication or MAC
address authentication.
z Login users: Users who log in using, for example, SSH, Telnet, FTP, or HyperTerminal.
You can configure separate authentication/authorization/accounting policies for all the other types of
users.
For a user who has logged in to the device, AAA can provide the command authorization service to
enhance device security: Allows the authorization server to check each command executed by the
login user and only authorized commands can be successfully executed.
Configuration Prerequisites
For remote authentication, authorization, or accounting, you must create the RADIUS or HWTACACS
scheme first. For RADIUS scheme configuration, refer to
Configuring RADIUS. For HWTACACS
scheme configuration, refer to
Configuring HWTACACS.
Creating an ISP Domain
An Internet service provider (ISP) domain represents a group of users belonging to it. For a username
in the userid@isp-name format, the access device considers the userid part the username for
authentication and the isp-name part the domain name.
In a networking scenario with multiple ISPs, an access device may connect users of different ISPs. As
users of different ISPs may have different user attributes (such as username and password structure,
service type, and rights), you need to configure ISP domains to distinguish the users. In addition, you
need to configure different attribute sets including AAA methods for the ISP domains.
