Chapter 4

Introduction to the Cisco IOS and SDM

Hands-on Labs

In this section, you will perform commands on a Cisco router that will help you understand

what you learned in this chapter.

You’ll need at least one Cisco router—two would be better, three would be outstanding. The

hands-on labs in this section are included for use with real Cisco routers. If you are using software

from RouterSim.com or Sybex, please use the hands-on labs found in those programs. It doesn’t

matter what series type router you use with these labs (i.e., 2500, 2600, 800, 1800, or 2800).

This chapter includes the following six labs:

Lab 4.1: Logging into a Router

Lab 4.2: Using the Help and Editing Features

Lab 4.3: Saving a Router Configuration

Lab 4.4: Setting Your Passwords

Lab 4.5: Setting the Hostname, Descriptions, IP Address, and Clock Rate

Lab 4.6: Installing SDM on Your Computer
