The AAA Server Node Test Case

---

If you purchased the AAA Server Emulation feature, you can use the AAA Server Node test case as a virtual AAA server in a test session. The virtual server provides authentication services for an SUT and can allocate MN IP addresses, responding to authentication requests sent by the SUT. It also responds to accounting requests, but does not maintain accounting records.

Using a Virtual AAA Server

Add the AAA Server Node test case to a test session containing a CDMA2000, GPRS, or Mobile IP test case, and configure the SUT to direct AAA request messages to the virtual server's IP address. One virtual server can service more than one SUT as long as the virtual server's message attribute configuration will produce response messages that are valid for the SUTs. For example, to provide AAA services for a CDMA2000 End-to-End Mobile IP test, you can configure different attribute values for responses to the PDSN-FAs and responses to the HA.

NOTE: If the virtual server receives a RADIUS Access Request containing the MN-HA SPI attribute from an HA during a CDMA2000 test, the server will respond with an Access Accept that contains the encrypted MN-HA SPI as defined in the nodal test case.

IMPORTANT: As with all co-resident test cases, when a AAA Server Node test case shares the same test server as another test case the maximum activation rate and capacity of the nodal test case is reduced. The maximum achievable activation rate is reduced by 10-20% depending on the application. The maximum number of simultaneous sessions is reduced by 50% since the test server must allocate resources for the sessions on both the MN and AAA sides. You can avoid these restrictions by running the AAA Server Node test case on another test server as shown in the diagram.

With each test case, you define:

• The virtual server's IP address

• The number of mobile subscribers and the user credentials that will be accepted during authentication, and the authentication methods supported

• The number of accounting sessions that will be supported

• MN address pools when the virtual server is responsible for allocating IP addresses

• RADIUS: The optional RADIUS and vendor-specific extended attributes included in the Access Accept and Accounting Response messages.  Attributes can be provisioned within the test case or obtained from a Test Data File. Response messages will be sent at the maximum rate possible.

• RADIUS: Optional CoA requests and the method used to trigger the requests.

• Diameter: The mandatory and optional Diameter and NAS Application AVPs, and the maximum rate at which sessions can be deactivated.
