Configuring Nortel Snas 4050-Specific Attributes Using The Srem - Nortel Secure Network Access Switch 4050 User Manual

184 Chapter 4 Configuring the domain
•
Configure the RADIUS server in accordance with the recommendations in
RFC 2866.
Certain Nortel SNAS 4050-specific attributes are sent to the RADIUS server
when you enable accounting (see
attributes using the SREM" on page
RADIUS, these attributes can be used for more detailed monitoring of Nortel
SNAS 4050 activity.
When you add an external RADIUS accounting server to the configuration, the
server is automatically assigned an index number. Nortel SNAS 4050 accounting
will be performed by an available server with the lowest index number. You can
control accounting server usage by reassigning index numbers (see
RADIUS accounting servers using the SREM" on page
Configuring Nortel SNAS 4050-specific attributes using the
SREM
The RADIUS accounting server uses Vendor-Id and Vendor-Type attributes in
combination to identify the source of the accounting information. The attributes
are sent to the RADIUS accounting server together with the accounting
information for the logged in user.
You can assign vendor-specific codes to the Vendor-Id and Vendor-Type
attributes for the Nortel SNAS 4050 domain. In this way, the RADIUS accounting
server can provide separate accounting information for each Nortel SNAS 4050
domain.
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.
The Internet Assigned Numbers Authority (IANA) has designated SMI Network
Management Private Enterprise Codes that can be assigned to the Vendor-Id
attribute (see http://www.iana.org/assignments/enterprise-numbers).
RFC 2866 describes usage of the Vendor-Type attribute.
