The switch forwards the accounting information it collects to the designated RADIUS server, where
the information is formatted, stored, and managed by the server. For more information on this
aspect of RADIUS accounting, see the documentation provided with your RADIUS server.
Acct-Session-ID options in a management session
The switch can be configured to support either of the following options for the accounting service
types used in a management session:
Unique Acct-Session-ID for each accounting service type used in the same management session
(the default)
Same Acct-Session-ID for all accounting service types used in the same management session
See Accounting service types” (page 185) for more information.
Unique Acct-Session-ID operation
In the Unique mode (the default), the various service types running in a management session operate
as parallel, independent processes. Thus, during a specific management session, a given service
type has the same Acct-Session-ID for all accounting actions for that service type. However, the
Acct-Session-ID for each service type differs from the ID for the other types.
NOTE: In Unique Acct-Session-ID operation, the Command service type is a special case in which
the Acct-Session-ID for each executed CLI command in the session is different from the IDs for other
service types used in the session and also different for each CLI command executed during the
session. That is, the ID for each successive CLI command in the session is sequentially incremented
from the ID value assigned to the immediately preceding CLI command in that session.
Figure 145 (page 188) shows Unique mode accounting operation for a new session in which two
commands are executed, and then the session is closed.
