Cisco® CallManager runs on a Windows2000 server. An important administrative task for server management is antivirus software. Enterprise tools such as ePolicy Orchestrator from McAfee have been developed to ensure antivirus software is effective across an entire enterprise. These tools can inventory, audit, and bring into compliance machines across an enterprise. Cisco Systems® has supported McAfee antivirus software running co-resident on Cisco CallManager for some time. Cisco now supports McAfee ePolicy Orchestrator agent running on Cisco CallManager servers.
This document outlines the procedures to configure McAfee ePolicy Orchestrator (ePO) 3.5 and McAfee 8.0i on a Cisco CallManager Media Convergence Server (MCS). This document assumes ePO agent and McAfee are installed on the Cisco CallManager server and that ePolicy Orchestrator is installed on a separate machine.
The high-level steps for setting up the ePO server and workstation policies for the Cisco CallManager servers follow:
1. Disable ScriptScan.
2. Disable Trace File Scanning.
3. Disable Scanning for Windows Protected Files.
4. Disable Heuristics Scanning.
The high-level steps for scheduling a reoccurring scan of a Cisco CallManager server follow:
1. Disable Inheriting of policies.
2. Set the scan to run during off-peak hours.
3. Exclude Trace File Scanning.
4. Exclude scanning of Windows Protected Files.
5. Disable Heuristics Scanning and set the maximum system usage to 10 percent.
If these steps are not followed correctly, system performance and call-processing capabilities could be impacted.
The following steps modify the policy configuration with ePO (Figure 1).
1. Open ePO and log in.
2. Expand Directory, Lost&Found, and the Server Group.
3. Select the Cisco CallManager server.
4. In the right window pane, select the Policies tab and Expand the VirusScan Enterprise 8.0 Policy group.
