Introduction

This document serves as a deployment guide for Cisco Expressway, detailing the processes for creating and maintaining clusters. It also applies to Cisco TelePresence Video Communication Server (VCS) where noted. The guide covers essential topics such as clustering prerequisites, forming a cluster, changing cluster configurations, connecting to other systems like Cisco TMS, and troubleshooting common issues.

Key Features and Benefits

Expressway clusters are designed to enhance the resilience and capacity of Expressway installations. Peers within a cluster share bandwidth, routing, zone, and configuration data, allowing endpoints to register with any peer. This ensures continuous service even if an endpoint loses connection to its initial peer. The guide also touches upon licensing, network conditions, and DNS configuration crucial for successful clustering.

Getting Started

To begin, ensure that all platform and software versions match across cluster peers. Network conditions must be optimal, with proper IP addressing, routing, and firewall configurations. Basic system configurations, including unique system names and domain configurations, are also vital. For detailed steps and specific configurations, refer to the sections on Clustering Prerequisites and Form a Cluster.
