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 configuring 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.
Follow these guidelines when you configure AAA accounting methods for an ISP domain:
• If you configure the accounting optional command, the limit on the number of local user
connections is not effective.
• The accounting method specified with the accounting default command is for all types of users and
has a priority lower than that for a specific access type.
• If you specify the radius-scheme radius-scheme-name local or hwtacacs-scheme
hwtacacs-scheme-name local option when you configure an accounting method, local accounting
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 accounting method configuration command, the
switch has no backup accounting method and performs only local accounting or does not perform
any accounting.
• Accounting is not supported for FTP services.
