Cisco Cisco NAC Appliance 4.9.5 Release Notes

This section describes known issues when integrating Cisco NAC Appliance:

 

When launching the CAM web console in Release 4.9 using Internet Explorer, you may see a “Choose 
a digital certificate” pop-up dialog with no options available in the selection window. This pop-up is a 
result of the way the CAM verifies CAS-to-CAM certificates for communication. If you click OK or 
Cancel, the dialog disappears and you can continue the web console session normally. If you want to 
ensure this pop-up does not appear in the future. you can apply the following custom security setting in 
Internet Explorer:

Go to Tools > Internet Options, click on the Security tab, and click Custom Level.

Scroll down and enable the Don’t prompt for client certificate selection when no certificate or 
only one certificate exists option.

Click OK.

This issue has not been observed when accessing the CAM with Mozilla Firefox or Google Chrome 
browsers.

The IP address release/renew process for Windows 7 and Windows Vista client machines running Cisco 
NAC Agent version 4.8.0.x that move from the authentication to access VLAN can take as long as 4 
minutes to complete.
