In the WebUI

To configure the Stateful 802.1x Authentication profile via the WebUI:

1.Navigate to the Configuration > Security > Authentication > L2 Authentication window.

2.In the Profiles list, select Stateful 802.1x Authentication Profile.

3.Click the Default Role drop-down list, and select the role assigned to stateful 802.1x authenticated users.

4.Specify the timeout period for authentication requests, from 1-20 seconds. The default value is 10 seconds.

5.Select the Mode checkbox to enable stateful 802.1x authentication.

In the CLI

Use the following commands to configure stateful 802.1x authentication via the command-line interface. The first set of commands defines the RADIUS server used for 802.1x authentication, and the second set assigns that server to a server group. The third set of commands associates that server group with the stateful 802.1x authentication profile, then sets the authentication role and timeout period.

(host)(config)# aaa authentication-server radius <server-name> acctport <port>

authport <port> clone <server> enable

host <ipaddr> key <psk>

nas-identifier <string> nas-ip <ipaddr> retransmit <number> timeout <seconds> use-md5

!

(host)(config)# aaa server-group group <server-group> auth-server <server-name>

!

(host)(config)# aaa authentication stateful-dot1x server-group <server-group>

default-role <role> enable

timeout <seconds>

Configuring Stateful NTLM Authentication

The Stateful NTLM Authentication profile requires that you specify a server group which includes the servers performing NTLM authentication, and the role to be assigned to users who are successfully authenticated. For details on defining a windows server used for NTLM authentication, see "Configuring a Windows Server" on page

When the user logs off or shuts down the client machine, the user remains in the authenticated role until the user ages out, that is, until the user has sent no traffic for the amount of time specified in the User Idle Timeout setting in the Configuration > Security > Authentication > Advanced page.

In the WebUI

To create and configure a new instance of a stateful NTLM authentication profile via the WebUI:

1.Navigate to the Configuration > Security > Authentication > L3 Authenticationpage.
