  • Current estimates and measurements predict that Internet traffic will continue to grow for many years to come. Driving this growth is the fact that the Internet has moved from a convenience to a mission-critical platform for conducting and succeeding in business. In addition, the provision of advanced broadband services to end users will continue to cultivate and prolong this growth in the future.

  • This lab is designed to walk you through a basic VLAN configuration using two Catalyst 1900 (or 2820) series switches. This lab shows you step-by-step what commands to type in and how to check that you have configured things correctly. Each switch must be configured with the Enterprise edition software. The Cisco IOS software CLI is not available if the switch has been configured with the Standard edition software.

  • For years now, data networks have become increasingly important. At first, networks were just a large corporate phenomenon. Now, almost any business with more than a few computers or more than one location has a data network. And now, with the growth of the Internet, many people’s home computers are often connected to a network. As data networks grow in size and importance, there must be a corresponding growth of people required to design, build, and maintain them.

  • 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....

  • This lab is a build-to-specifications test. Numerous issues need to be addressed for this lab to work correctly. The lab illustrates some of the different ways to configure a router as a frame relay switch and emphasizes the differences between a partially meshed switch and a fully meshed switch. When you thoroughly understand the differences between each configuration, you will be prepared to configure your own frame relay switch for any given practice scenario.

  • Cable a network similar to the one in the diagram. The configuration output used in this lab is produced from a 2950 series switch. Any other switch used may produce different output. The following steps are to be executed on each switch unless specifically instructed otherwise. Instructions are also provided for the 1900 Series switch, which initially displays a User Interface Menu. Select the “Command Line” option from the menu to perform the steps for this lab. Start a HyperTerminal session. Note: Go to the erase and reload instructions at the end of this lab.

  • Your network switching equipment currently includes a 4006 Core switch and a 2900XL access switch. Your network is segmented into four functional VLANs for better network management. VLANs include “Accounting”, “Marketing” and “Engineering” for the users and “default” used for the native VLAN network management. After deciding on your subnet ranges and VTP information, illustrated below, your next step is to implement Inter-VLAN routing. Inter-VLAN routing will allow individuals and servers on your Virtual LANs to exchange information.

  • Multiprotocol label switching (MPLS) combines the performance and capabilities of Layer 2 (data link layer) switching with the proven scalability of Layer 3 (network layer) routing. MPLS enables service providers to meet the challenges of explosive growth in network utilization while providing the opportunity to differentiate services without sacrificing the existing network infrastructure. The MPLS architecture is flexible and can be employed in any combination of Layer 2 technologies.

  • In every introductory class we teach we get students who are either puzzled about router essentials or switching essentials or both. This switching essentials white paper will give you the basics that will make learning about switching a little less painless when you sit in a course like ICND1, ICND2, CCNA Boot Camp or BCMSN. Switching is an interesting topic. It could be an easy thing in your network, or it could be something that keeps you up nights. Switching can be simple, allowing us to connect our users from various systems (host systems and phones), or it can be a...

  • 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....

  • Fiber is on the increase within wireless switching centers as they evolve to meet rising bandwidth demand, requiring modifications to the traditional wireless switching office. With any increase in fiber, developing and maintaining good fiber cable management quickly becomes an important consideration. As wireless switching centers – we’ll refer to them as mobile switching centers (MSCs) in this paper – are being retrofitted to increase density and capability, a good fiber cable management system ensures quality-of-service is maintained....
