Using Symantec/Norton AntiVirus
with Cisco CallManager 3.3

1 Introduction

Any Windows 2000 Server is recommended to have virus protection and the Cisco CallManager is no exception. While the installation and configuration of Symantec/Norton antivirus is very easy, there are a few important steps that need to be taken. This document will provide information on the installation and configuration of Symantec/Norton Antivirus on the Cisco CallManager platform (this includes the newest Norton Antivirus Corporate Edition Version 7.61 and Symantec Antivirus Corporate Edition Version 8.0 releases).

2 Scope

This paper provides a detailed description of the Norton Antivirus Product available from Symantec for use on the Cisco Call Manager versions 3.3(x)x. The paper describes the need for the product, a description of the product and product features/functionality.

3 Norton Product Overview

Norton AntiVirus is an application that provides comprehensive virus prevention, detection, and elimination software for your computer. It automatically finds and repairs infected files to keep your data secure.

5 Performance

During the testing we noticed the following:

1. Norton active virus scans does not add any CPU memory overhead.

2. Drive scanning takes up lot of CPU and is not recommended during call processing.

3. Virus updates use little CPU so can be scheduled to run during low traffic.

6 Required Cisco AVVID hardware and software levels

Cisco Hardware levels are not a concern of the Norton, please refer the hardware requirements section of the Norton documentation. Below are the tested CallManager Software levels, please refer to the list below for all supported CCM Versions.

Cisco CallManager Version 3.3(x)x or greater within the CCM 3.3 version.

Cisco CallManager Version 3.2(2c) or higher

Cisco CallManager Version 3.3(2) or higher

8 Configuration

For normal operation on Cisco CallManager 3.X, the default settings for Norton antivirus are fine. There are two important considerations, however.

8.1.1 Scheduled File Scanning Can Have a Negative Impact on the Server

There is a difference between the protection Norton offers by running in the background and scheduled file scanning of the entire directory structure. Scheduled file scanning is very processor intensive. This could potentially impact call processing if it occurred during high volume traffic. As such, it is critical to only schedule a complete file scan during the middle of the night or other non-peak time schedules.

8.1.2 Using Cisco IDS Host Sensor and Norton


Note: In order for Norton and the Cisco Host IDS Sensor to co-exist on the same server, Norton should be configured to not scan the directory C:\Program Files\Cisco IDS where the Cisco Host IDS Sensor or Console is configured.


9 Un-installation

If you need to uninstall Norton AntiVirus

If you need to remove Norton AntiVirus from your computer, you can use the Add/Remove Programs option from the Windows Control Panel or the Uninstall Norton AntiVirus option from the Programs menu.

During uninstall, Windows may indicate that it is installing software. This is a standard Microsoft installation message and can be disregarded.
