AAA supports the following authorization methods:
•
No authorization (
none
)—The router performs no authorization exchange. After passing
authentication, non-login users can access the network, FTP users can access the root directory of
the router, and other login users have only the right of Level 0 (visiting).
•
Local authorization (
local
)—The router performs authorization according to the user attributes
configured for users.
•
Remote authorization (
scheme
)—The router cooperates with a RADIUS or HWTACACS server to
authorize users. RADIUS authorization is bound with RADIUS authentication. RADIUS authorization
can work only after RADIUS authentication is successful, and the authorization information is
carried in the Access-Accept message. HWTACACS authorization is separate from HWTACACS
authentication, and the authorization information is carried in the authorization response after
successful authentication. Configure local authorization or no authorization as the backup method
to be used when the remote server is not available.
Before configuring authorization methods, complete the following tasks:
1.
For HWTACACS authorization, configure the HWTACACS scheme to be referenced first. For
RADIUS authorization, the RADIUS authorization scheme must be the same as the RADIUS
authentication scheme. Otherwise, it does not take effect.
2.
Determine the access type or service type to be configured. With AAA, configure an authorization
scheme for each access type and service type, limiting the authorization protocols that can be used
for access.
3.
Determine whether to configure an authorization method for all access types or service types.
