If you specify the radius-scheme radius-scheme-name local , hwtacacs-scheme hwtacacs-scheme-name [
local | none ] option when you configure an authorization method, local authorization or no
authorization is the backup method and is used only when the remote server is not available.
If you specify only the
local or none keyword in an authorization method configuration command, the
switch has no backup authorization method and performs only local authorization or does not perform
any authorization.
Configuring AAA accounting methods for an ISP domain
In AAA, accounting is a separate process at the same level as authentication and authorization. This
process sends accounting start/update/end requests to the specified accounting server. Accounting is
optional.
AAA supports the following accounting methods:
•
No accounting (none) —The system does not perform accounting for the users.
•
Local accounting (local) —Local accounting is implemented on the NAS. It counts and controls the
number of concurrent users who use the same local user account; it does not provide statistics for
charging. The maximum number of concurrent users using the same local user account is set by the
access-limit command in local user view.
•
Remote accounting (scheme) —The NAS works with a RADIUS server or HWTACACS server for
accounting. You can configure local or no accounting as the backup method, which is used when
the remote server is not available.
By default, an ISP domain uses the local accounting method.
Before you configure accounting methods, complete the following tasks:
1.
For RADIUS or HWTACACS accounting, configure the RADIUS or HWTACACS scheme to be
referenced first. The
local and none accounting methods do not require a scheme.
2.
Determine the access type or service type to be configured. With AAA, you can configure an
accounting method for each access type and service type, limiting the accounting protocols that
can be used for access.
3.
Determine whether to configure an accounting method for all access types or service types.
To configure AAA accounting methods for an ISP domain:

to use network resources when
no accounting server is
available or when
communication with all
accounting servers fails.
4. Specify the default accounting
method for all types of users.
accounting default { hwtacacs-scheme
hwtacacs-scheme-name [ local ] |
local | none | radius-scheme radius-
scheme-name [ local ] }
Optional.
It is set to
local by default.
