When you add an external RADIUS audit server to the configuration, the server is 
automatically assigned an index number. You can add several RADIUS audit 
servers, for backup purposes. Nortel SNAS 4050 auditing will be performed by an 
available server with the lowest index number. You can control audit server usage 
by reassigning index numbers (see 

).

For information about configuring a RADIUS accounting server to log portal user 
sessions, see 

The RADIUS audit server uses Vendor-Id and Vendor-Type attributes in 
combination to identify the source of the audit information. The attributes are sent 
to the RADIUS audit server together with the event log information. 

Each vendor has a specific dictionary. The Vendor-Id specified for an attribute 
identifies the dictionary the RADIUS server will use to retrieve the attribute value. 
The Vendor-Type indicates the index number of the required entry in the 
dictionary file.

).

RFC 2866 describes usage of the Vendor-Type attribute.

Contact your RADIUS system administrator for information about the 
vendor-specific attributes used by the external RADIUS audit server.

To simplify the task of finding audit entries in the RADIUS server log, do the 
following:

In the RADIUS server dictionary, define a descriptive string (for example, 

NSNAS-SSL-Audit-Trail

).

Map this string to the Vendor-Type value.
