RADIUS Authentication and Accounting

Configuring RADIUS Accounting

■Start-Stop:

•Send a start record accounting notice at the beginning of the account- ing session and a stop record notice at the end of the session. Both notices include the latest data the switch has collected for the requested accounting type (Network, Exec, or System).

•Do not wait for an acknowledgement.

The system option (page 5-22) ignores start-stopbecause the switch sends the accumulated data only when there is a reboot, reload, or accounting on/off event.

■Stop-Only:

•Send a stop record accounting notice at the end of the accounting session. The notice includes the latest data the switch has collected for the requested accounting type (Network, Exec, or System).

•Do not wait for an acknowledgment.

The system option (page 5-22) always delivers stop-onlyoperation because the switch sends the accumulated data only when there is a reboot, reload, or accounting on/off event.

Syntax: [no] aaa accounting < exec network system > < start-stop stop-only > radius

Configures RADIUS accounting type and how data will be sent to the RADIUS server.

For example, to configure RADIUS accounting on the switch with start-stopfor exec functions and stop-onlyfor system functions:

Configures exec and system accounting and controls.
