To do...
Configure an authentication
scheme for the ISP domain
Configure a HWTACACS
authentication scheme for user
level switching
Configure an authorization
scheme for the ISP domain
Configure an accounting
scheme for the ISP domain
RADIUS scheme and local scheme do not support the separation of authentication and
authorization. Therefore, pay attention when you make authentication and authorization
configuration for a domain: When the scheme radius-scheme or scheme local command is
executed and the authentication command is not executed, the authorization information returned
from the RADIUS or local scheme still takes effect even if the authorization none command is
executed.
The Switch 4200G adopts hierarchical protection for command lines so as to inhibit users at lower
levels from using higher level commands to configure the switches. For details about configuring a
HWTACACS authentication scheme for low-to-high user level switching, refer to Switching User
Level in the Command Line Interface Operation.
Configuration guidelines
Suppose a combined AAA scheme is available. The system selects AAA schemes according to the
following principles:
If authentication, authorization, accounting each have a separate scheme, the separate schemes
are used.
If you configure only a separate authentication scheme (that is, there are no separate authorization
and accounting schemes configured), the combined scheme is used for authorization and
accounting. In this case, if the combined scheme uses RADIUS or HWTACACS, the system never
uses the secondary scheme for authorization and accounting.
If you configure no separate scheme, the combined scheme is used for authentication,
authorization, and accounting. In this case, if the system uses the secondary local scheme for
authentication, it also does so for authorization and accounting; if the system uses the first scheme
Use the command...
authentication
{ radius-scheme
radius-scheme-name [ local ] |
hwtacacs-scheme
hwtacacs-scheme-name
[ local ] | local | none }
authentication super

authorization { none |

accounting { none |
