Accounting

Accounting is the action of recording a user's activities on the device for the purposes of billing and/or security. It follows the authentication and authorization actions. If the authentication and authorization is not performed via TACACS+, there are no TACACS+ accounting mes- sages sent out.

You can use TACACS+ to record and track software logins, configuration changes, and inter- active commands.

The GbE Switch Module supports the following TACACS+ accounting attributes:

„protocol (console/telnet/ssh/http)

„start_time

„stop_time

„elapsed_time

„disc-cause

NOTE – When using the Browser-Based Interface, the TACACS+ Accounting Stop records are sent only if the Quit button on the browser is clicked.

Command Authorization and Logging

When TACACS+ Command Authorization is enabled (/cfg/sys/tacacs/cauth ena), Alteon OS configuration commands are sent to the TACACS+ server for authorization. When TACACS+ Command Logging is enabled (/cfg/sys/tacacs/clog ena), Alteon OS configuration commands are logged on the TACACS+ server.

The following examples illustrate the format of Alteon OS commands sent to the TACACS+ server:

authorization request, cmd=cfgtree, cmd-arg=/cfg/l3/if accounting request, cmd=/cfg/l3/if, cmd-arg=1 authorization request, cmd=cfgtree, cmd-arg=/cfg/l3/if/ena accounting request, cmd=/cfg/l3/if/ena

authorization request, cmd=cfgtree, cmd-arg=/cfg/l3/if/addr accounting request, cmd=/cfg/l3/if/addr, cmd-arg=10.90.90.91

authorization request, cmd=apply accounting request, cmd=apply
