Overview

Introduction

The Interface Configuration and Cabling module provides you with the instructions and Cisco hardware to develop your hands on skills in understanding, configuring and troubleshooting various interface and cable issues. This module includes the following activities:

  • Duplex and speed configurations on links between network devices
  • Examining methods of observing collisions and other errors
  • Cabling issues and MDI/MDIX configuration

Exercise 1 - Interface Configuration Options

An interface is an entity through which network devices are interconnected. All interfaces exist within the Physical and Data Link layers of the OSI model, although some interfaces do have features in higher layers as well.

In this exercise, you will examine the configuration parameters that affect the connectivity of interfaces within the first two layers of the OSI model.

Exercise 2 - Examining Collisions and Other Types of Errors

Some of the most difficult types of faults on a network to diagnose and correct are those that are of an intermittent nature or those that cause a degradation to network performance rather than a complete loss of connectivity. Many of these types of faults can be traced back to errors on interfaces including collisions and frame errors.

Many of these errors can be diagnosed at the interface level. In this exercise, you will examine and diagnose errors that are found on interface counters on a switch and will decide on appropriate action to rectify these errors.

Exercise 3 - Cabling Issues

Errors on an interface can often be caused by faulty or incorrect cable installations. This is true for both copper and fiber media. A bad copper cable connection, a slightly too long UTP cable or a bend of a fiber optic cable that has a slightly-too-small radius could be some of the reasons why errors occur on an interface.

In this exercise, you will examine the types of ports that exist on Cisco devices, what kinds of media they will accept and some configurations that affect the types of cables that you can use.
