Procedure

1. Navigate to Cisco NAC → Agent Deployment.
2. In the client tree, click the root domain icon () to include all clients or select specific domains or clients.
3. Click Deploy Agent.
4. If you did not accept the terms of the Cisco License Agreement during the installation of the OfficeScan server, the license information appears. Read the license agreement and click Yes to agree to the terms.
5. Select Install/Upgrade Cisco Trust Agent.
6. (Optional) Select Uninstall Cisco Trust Agent when OfficeScan client is uninstalled.

   Note Also use this screen to uninstall or preserve CTA status on clients. Preserving the CTA status means preventing an installation from overwriting CTA if one is already installed. Unless you are upgrading or are certain that you have never installed CTA on any of the clients you selected, you may want to use this option, otherwise the server will reinstall CTA and your settings will be lost.

7. If you selected domain(s) or client(s) in the client tree, click Save. If you clicked the root domain icon, choose from the following options:
   • Apply to All Clients: Applies settings to all existing clients and to any new client added to an existing/future domain. Future domains are domains not yet created at the time you configured the settings.
   • Apply to Future Domains Only: Applies settings only to clients added to future domains. This option will not apply settings to new clients added to an existing domain.

   Note If the OfficeScan client to which you deploy the agent is not online when you click Install Cisco Trust Agent, OfficeScan automatically fulfills the task request when the OfficeScan client becomes online.
