AAA Configuration
With CVDM-VPNSM, you can implement and configure authentication, authorization, and accounting (AAA) on your VPN module. AAA performs the following services:
•
Authentication identifies users before they are permitted access to the network or network services. Authentication provides the method for identifying users, including username and password, challenge and response, messaging support, and, depending on the security protocol selected, encryption.
•Authorization assembles a set of attribute-value pairs that describe privileges for the identified user. These attribute-value pairs are compared to the information contained in a Remote Authentication Dial-In User Service (RADIUS) server database.
Note For more information on RADIUS, see Editing Global RADIUS Settings.
•Accounting logs the services accessed and the network resources consumed by users. Accounting provides the method for collecting and distributing information such as user identities, start and stop times, executed commands, number of packets, and number of bytes.
This chapter contains the following topics:
•Viewing AAA Settings
•Configuring AAA Servers
•Configuring Authentication Lists
•Configuring Authorization Lists
•Configuring Accounting Lists
Viewing AAA Settings
From the AAA main page, you can view the AAA settings that are currently configured on the module. To access this page, click Setup at the top of the window and then click AAA Configuration (see Figure 6-1).
Figure 6-1 AAA Main Page
Configuring AAA Servers
To access the AAA overview page, click Setup at the top of the window, click AAA Configuration from the left-most pane, and then click AAA from the selector.
From the AAA Configuration overview page, you can:
•Enable AAA on the device by clicking the Enable AAA link at the top of the page.
Note You can only enable AAA if the enable password for a level 15 user has already been set. Until you have done so, you will not be able to make any configuration changes. However, you will be able to view any AAA-related configuration settings that have already been set on the device.
•View global RADIUS server settings.
•View detail information for the AAA servers configured on the device.
•Add a new AAA server. See Adding AAA Servers for more information.
•Edit the parameters for an existing AAA server. See Editing AAA Servers for more information.
•Delete an existing AAA server.
The following table describes the information provided on the AAA Configuration overview page.

Editing Global RADIUS Settings
RADIUS is an open and scalable client/server security system designed to authenticate remote users. RADIUS-based authentication works by comparing a secret username and password to data stored in a central location, called the RADIUS server. The RADIUS server receives authentication requests and either accepts or rejects them on the basis of information stored in the RADIUS server database. If a submitted username and password are correct, the RADIUS server returns an authentication acknowledgment to the client requesting the services.
From this dialog box, you can edit the RADIUS server settings for the VPN module.
Step 1 From the RADIUS Global Settings pane on the AAA Configuration overview page, click Edit. The Edit RADIUS Settings dialog box appears.
