Tip

Understanding the CSAgent Patch

In ACS SE the CSAgent service is implemented as a pre-installed patch. You must stop CSAgent before
you can install any patch or upgrade. Although, as a patch, the CSAgent can be rolled back, the preferred
method for disabling this service is simply to stop it. Once stopped, the CSAgent service does not restart
when the system is restarted; you must explicitly restart the service for it to operate. For more
information, see the User Guide for Cisco Secure Access Control Server.

If you do not include the specific patch application name as a parameter following the rollback
command, the system displays the list of patches that can be rolled back. Use this list to identify
the patch application name, type rollback followed by the patch application name, and then
press Enter.
