Cisco NAC Web Agent
Figure 10-37 ActiveX Installation Notice
4.
If the user’s web browser settings are configured to verify actions like installing an ActiveX control
on the client machine, the user may need to verify the action. For example, in the case of Microsoft
IE, the user may need to click on a status bar that appears in the browser window and choose the
Install ActiveX Control option from the resulting pop-up to validate the ActiveX process.
If the ActiveX control fails to initialize, the user sees an ActiveX installation notice like the one in
Figure 10-38 and if you have set up the Cisco NAC Appliance system to try to download the Web
Agent install files via Java applet should the ActiveX method fail, the Cisco NAC Appliance system
attempts to download the Web Agent installation files via Java applet.
Otherwise, the user will not be able to use the Cisco NAC Web Agent for login and will either have
to contact the Cisco NAC Appliance network administrator to try and help troubleshoot issues with
the installation process, or accept “Restricted” network access for the time being until they can fix
the Web Agent installation problem.
Note If you specify that the Java applet method is preferred using the Web Client (ActiveX/Applet)
option in the Administration > User Pages > Login Page configuration screen, the order of
these possibilities is reversed—the user sees a Java applet failure notice before the ActiveX
control attempts to install the Web Agent files on the client machine.
