Configuring authentication methods for an ISP domain
In AAA, authentication, authorization, and accounting are separate processes. Authentication refers to
the interactive authentication process of username/password/user information during an access or
service request. The authentication process neither sends authorization information to a supplicant nor
triggers any accounting.
AAA supports the following authentication methods:
• No authentication (none)—No authentication is performed. This method trusts all users and is not
for general use.
• Local authentication (local)—Authentication is performed by the NAS, which is configured with the
user information, including the usernames, passwords, and attributes. Local authentication allows
high speed and low cost, but the amount of information that can be stored is limited by the size of
the storage space.
• Remote authentication (scheme)—The NAS cooperates with a RADIUS or HWTACACS server to
authenticate users. Remote authentication provides centralized information management, high
capacity, high reliability, and support for centralized authentication service for multiple NASs. You
can configure local or no authentication as the backup method, which will be used when the remote
server is not available. The no authentication method can only be configured for LAN users as the
backup method of remote authentication.
