Chapter 9 Configuring Cisco NAC Appliance for Agent Login and Client Posture Assessment
Post-Configuration and Agent Maintenance on the CAM
Post-Configuration and Agent Maintenance on the CAM
Once you have configured Agent login and client posture assessment, and users are able to successfully
access the Cisco NAC Appliance network, you can use the following topics to manage Agent versions
on client machines in your network:
• Manually Uploading the Agent to the CAM, page 9-100
• Downgrading the Agent, page 9-101
• Configure Agent Auto-Upgrade, page 9-102
Note If you are uploading an older (pre-release 4.6(1) Windows Clean Access Agent to the CAM, refer to the
uploading and downgrading instructions in the Cisco NAC Appliance - Clean Access Manager
Installation and Configuration Guide, Release 4.5(1).
Manually Uploading the Agent to the CAM
When performing a software upgrade or new install of the CAM/CAS, it is not necessary to upload Agent
installation files since they are automatically included with the CAM software. In certain cases, you can
manually upload either the Windows Cisco NAC Agent Installation File (nacagentsetup-win.tar.gz) or
Mac OS X Agent Installation File (CCAAgentMacOSX-4.9.x.y-k9.tar.gz) directly to the CAM (for
example, if you need to reinstall the Agent or downgrade the version of the Agent distributed to new
users—see Downgrading the Agent, page 9-101 for details).
To support Windows Clean Access Agent backward compatibility, you can also manually upload the
Windows Clean Access Agent Setup File (CCAAgentSetup-4.x.y.z.tar.gz) directly to the CAM. This
feature allows administrators to revert to a previous Windows Agent Setup file for distribution. You can
manually upload the Agent Setup File using the CAM Device Management > Clean Access > Clean
Access Agent > Distribution web console page.
Note The CAM will automatically publish the Agent Installation/Setup file to the connected CAS(s) when the
file is uploaded manually. There is no version check while publishing, so the Agent Installation/Setup
can be downgraded or replaced. For details on version compatibility for the CAM/CAS and Agent, refer
to Support Information for Cisco NAC Appliance Agents, Release 4.5 and Later.
Caution You must upload the Agent file as a tar.gz file (without untarring it) to the CAM. Make sure you do NOT
extract the .exe file before uploading.
