How to configure Radius using Avalanche

1. Introduction to RADIUS
RADIUS (Remote Authentication Dial In User Service) is an AAA (authentication,
authorization, and accounting) protocol for controlling access to network resources.
RADIUS is commonly used by service providers and corporations for managing access to
the Internet or internal networks.
RADIUS servers provide authentication for different users based on their agreement with
service providers. Avalanche emulates a number of users requesting authentication from a
RADIUS server to test the following scenarios:
1) Authentication server performance
2) Impact of authentication on the infrastructure
Note: The current implementation of RADIUS allows you to create a client-only test.
RADIUS server emulation is not supported.
2. Configuring RADIUS
1) Created an Application test to emulate only clients.
2) Completed entries on other tabs to define load, associations, and so on that are
required for all tests.
3) Ensure that your RADIUS server is up and running, and that you can ping the RADIUS
server from the network on which Avalanche resides.
4) On the RADIUS server, configure all the user names, user groups, passwords, and
shared secrets that you will be using for the test.

5) If desired, you can create a forms database for the user names and passwords for the
supplicants over each NAS. Avalanche emulates supplicants, as well as a virtual NAS.
Each IP address in the client subnet corresponds to a NAS.
The following forms database entries are examples:
u1,p1
u2,p2
6) Use the RADIUS Action list to specify the content of the RADIUS Authentication,
Authorization, Accounting (AAA) session, including supplicants and their individual
parameters. Here with an example,
RADIUS://192.168.1.1 IDENTITY=Form_0001.$1 PASSWORD=Form_0001.$2
SECRET=NAS_password AUTH=MD5
1 get http://192.168.1.1/index.html
RADIUS END

7) Use the RADIUS area on the Client Profiles tab to enable and disable various
attributes for RADIUS Authentication and Accounting. You can add, edit, and delete
the various attributes required for RADIUS in accordance with RFCs 2865 and 2866.
8) Click the Run Test icon to start test.
9) Click the Client Run-Time Stats button. The Client Run-Time Statistics window appears.
10) Click the 802.1X/RADIUS tab to view statistics on RADIUS authentication traffic being
generated. These statistics show the network and/or device under test behavior when
responding to RADIUS authentication traffic.

11) When the status message indicates that the run has finished, you can view the test
results. The Client RADIUS Incremental Statistics and Client RADIUS Summary
Statistics are contained in the client realtime.csv and summary.csv files, respectively.
The Client 802.1x Incremental Statistics and Client 802.1x Summary Statistics are
contained in the client realtime.csv and summary.csv files, respectively.
