  • For many years I have been a consultant for different companies and have written books on switch and router configurations and troubleshooting. During my years as a consultant I have had to either install, administer, or troubleshoot switching problems and configurations for switches without a good handbook. I have constantly gone through bookstores looking for a book on Cisco switch troubleshooting and configurations that didn’t deal with a Cisco curriculum. Guess what? I couldn’t find one!

  • ATM is a packet-switched technology based on a 53-byte packet called a cell. Each cell is divided into a 5-byte header and a 48-byte payload. The short, fixed length cell reduces delay and jitter, allowing time sensitive information such as voice and video to be transported along with data. There are various transmission media and rates available with bandwidth measured in megabits to gigabits.

  • This chapter presents the basics of configuring the 1900 and 2950 Catalyst switches as well as Cisco routers. As you continue throughout this book, you will build upon these fundamental and important concepts for accessing, configuring, and managing your Cisco devices. I am making the assumption that you have never configured a Cisco device before and therefore will begin with the very basics by explaining the operating system that these devices use, the advantages that Cisco’s operating system provides, and how to use some basic operating system commands to configure your Cisco device....

  • 1. STEPPER MOTOR SYSTEMS OVERVIEW Motion Control, in electronic terms, means to accurately control the movement of an object based on either speed, distance, load, inertia or a combination of all these factors. There are numerous types of motion control systems, including; Stepper Motor, Linear Step Motor, DC Brush, Brushless, Servo, Brushless Servo and more. This document will concentrate on Step Motor technology. In Theory, a Stepper motor is a marvel in simplicity. It has no brushes, or contacts.

  • Bridges and switches are both layer-2 devices, functioning at the data link layer of the OSI Reference Model. Even though they are both layer-2 devices and have many similarities between them, they also have many differences. With advancements in hardware and technology, switches perform faster and have many more features. However, the basic functions of these two devices are the same. This chapter covers the functions of bridges and switches, the Spanning Tree Protocol (STP), and basic switch configuration tasks on Cisco’s Catalyst 1900 and 2950....
