Book Description
The definitive, up-to-date guide to planning, configuring, and administering Cisco call processing and voice messaging.
This book brings together all the hands-on knowledge you need to successfully configure and administer Cisco’s flagship IP voice systems, including Cisco Unified Communications Manager (CUCM), Unity, and Unity Connection. Fully updated for the new CUCM, Unity, and Unity Connection, version 8, it presents step-by-step procedures for every common and complex task that installers, integrators, and administrators will encounter.
Long-time Cisco voice implementer and instructor David Bateman begins with clear, well-organized explanations of Cisco Voice over IP technology, including its key functions and devices. Next, he guides you through preparation and deployment, including configuring CUCM for maximum performance, removing DNS dependencies, defining enterprise parameters, configuring regions, and enforcing security.
The author presents quick access, step-by-step solutions for dozens of post-deployment tasks, each with thorough instructions and cross-references to prerequisite tasks wherever needed. He demonstrates how to integrate features to create more powerful IP voice systems, thoroughly introduces Cisco’s new management interface, and provides extensive coverage of the latest feature enhancements.

Book Description
For system administrators, network engineers, and security analysts, it is essential to keep a track of network traffic.
Zenoss Core is an enterprise-level systems and network monitoring solution that can be as complex as you need it to be. And while just about anyone can install it, turn it on, and monitor “something”, Zenoss Core has a complicated interface packed with features. The interface has been drastically improved over version 2, but it’s still not the type of software you can use intuitively – in other words, a bit of guidance is in order.
The role of this book is to serve as your Zenoss Core tour guide and save you hours, days, maybe weeks of time.
This book will show you how to work with Zenoss and effectively adapt Zenoss for System and Network monitoring. Starting with the Zenoss basics, it requires no existing knowledge of systems management, and whether or not you can recite MIB trees and OIDs from memory is irrelevant. Advanced users will be able to identify ways in which they can customize the system to do more, while less advanced users will appreciate the ease of use Zenoss provides. The book contains step-by-step examples to demonstrate Zenoss Core’s capabilities. The best approach to using this book is to sit down with Zenoss and apply the examples found in these pages to your system.
The book covers the monitoring basics: adding devices, monitoring for availability and performance, processing events, and reviewing reports. Download Now »

Book Description
The practical guide to deploying IPv6 in campus, WAN/branch, data center, and virtualized environments
IPv6 for Enterprise Networks brings together all the information you need to successfully deploy IPv6 in any campus, WAN/branch, data center, or virtualized environment. Four leading Cisco IPv6 experts present a practical approach to organizing and executing your large-scale IPv6 implementation. They show how IPv6 affects existing network designs, describe common IPv4/IPv6 coexistence mechanisms, guide you in planning, and present validated configuration examples for building labs, pilots, and production networks.
The authors first review some of the drivers behind the acceleration of IPv6 deployment in the enterprise. Next, they introduce powerful new IPv6 services for routing, QoS, multicast, and management, comparing them with familiar IPv4 features and behavior. Finally, they translate IPv6 concepts into usable configurations. Up-to-date and practical, IPv6 for Enterprise Networks is an indispensable resource for every network engineer, architect, manager, and consultant who must evaluate, plan, migrate to, or manage IPv6 networks.
- Identify how IPv6 affects enterprises
- Understand IPv6 services and the IPv6 features that make them possible
- Review the most common tranisition mechanisms including dual-stack (IPv4/IPv6) networks, IPv6 over IPv4 tunnels, and IPv6 over MPLS Download Now »
