Configuration prerequisites

The device supports two methods for Web authentication, which are local authentication and RADIUS authentication.

To use the local authentication method, configure usernames and passwords on the access device. User authentication is performed on the access device directly.

When using the RADIUS authentication method, the device acts as a RADIUS client and cooperates with the RADIUS server to perform authentication for users. Before you configure Web authentication by using the RADIUS server, make sure the following requirements are met:

• The RADIUS server has been installed and configured properly.

• The authentication client, access device, and RADIUS server can reach each other.

• The local portal Web server has been configured and can provide Web authentication pages. For more information about the local portal Web server configuration, see "Configuring portal authentication".

• Usernames and passwords of the users are configured on the RADIUS server. The RADIUS client configuration is performed on the access device. For information about the RADIUS client configuration, see "Configuring AAA."
