Introduction
The Cisco TelePresence Video Communication Server (VCS) software simplifies session management and control of
telepresence conferences. It provides flexible and extensible conferencing applications, enabling organizations to
benefit from increased employee productivity and enhanced communication with partners and customers.
The VCS delivers exceptional scalability and resiliency, secure communications, and simplified large-scale
provisioning and network administration in conjunction with Cisco TelePresence Management Suite (Cisco TMS).
The VCS interworks transparently with Cisco Unified Communications Manager (Unified CM), bringing rich
telepresence services to organizations with Unified CM. It also offers interoperability with third-party unified
communications, IP telephony networks, and voice-over-IP (VoIP) systems.
This document describes how to configure a VCS Expressway and a VCS Control as the cornerstones of a basic
video infrastructure deployment. It takes you through the following tasks:
1. Using the Service Setup Wizard to select the services you want to use and to apply the corresponding keys
(licenses).
2. Configuring system parameters and routing information.
3. Checking that the system is working as expected.
4. Configuring optional items such as Cisco TMS, system logging, and access restrictions.
Advanced configuration
This document also provides detailed DNS, NAT, and firewall configuration information. In each case we assume that
you have a working knowledge of how to configure these systems. The appendices to the document provide detailed
reference information, as follows:
■ VCS configuration details used in this document are listed in Appendix 1: Configuration Details, page 53.
■ DNS records required for the example deployment used in this document are in Appendix 2: DNS Records,
page 57.
■ Details of required NAT and firewall configurations are in Appendix 3: Firewall and NAT Settings, page 59.
This document describes a small subset of the numerous NAT and firewall deployment options that are made
possible by using the VCS Expressway dual network interface and NAT features.
■ How to deploy your system with a static NAT and Dual Network Interface architecture is explained in Appendix
4: Advanced Network Deployments, page 63.
For descriptions of all system configuration parameters, see the VCS Administrator Guide and the VCS web
application’s online field help and page help .
Example configuration values used in this guide
For ease of reading this guide is based around an example deployment, which uses the following assumed
configuration values throughout:
 VCS Control VCS Expressway
LAN1 IPv4 address 10.0.0.2 192.0.2.2
IPv4 gateway 10.0.0.1 192.0.2.1
LAN1 subnet mask 255.255.255.0 255.255.255.0
Domain name internal-domain.net example.com
Information in other deployment guides
This document does not describe how to deploy a clustered system, or systems running device provisioning, device
authentication, or FindMe applications. For more details about these features, see the following documents:
