Introduction

The Device Maintenance Procedures module provides you with the instructions and Cisco hardware to develop your hands on skills in routine maintenance procedures for Cisco devices. This module includes exercises that will cover the following topics:

  • File system management
  • Backing up, restoring and upgrading Cisco IOS files
  • Examining IOS Licensing features and procedures
  • Password recovery and configuration register

Exercise 1 - Managing IOS Files and Procedures

The Internetwork Operating System or IOS is the operating system used by many Cisco devices. The IOS is kept in an IOS file on the flash memory of the device and is uncompressed and loaded into RAM when the device boots up. Like any other operating system, it can be upgraded to allow for new functionality or to repair any bugs that have been found.

In this exercise, you will examine the IOS file, learn how to back it up and update it as well as understand how IOS licensing functions.

Exercise 2 - Password Recovery

It has happened to all of us. Whether you received a previously configured Cisco device and you don’t know its password, or you’ve forgotten the password you configured several years ago, you are unable to connect to a device, and you need to recover its password.

This exercise describes the password recovery procedure that can be followed in such cases.
