Cisco IOS Troubleshooting Tools

Introduction

The Cisco IOS Troubleshooting Tools module provides you with the instructions and Cisco hardware to develop your hands-on skills in using the troubleshooting tools that the Cisco IOS provides. This module includes exercises that will cover the following topics:

• Using simple ping and extended ping
• Using traceroute

Exercise 1 - Ping and Extended Ping

One of the most basic network troubleshooting tools is the echo request using the ICMP protocol. This is more commonly known as a ping. Ping is often the first tool that is used when troubleshooting network connectivity issues.

In this exercise, you will examine and use traceroute and observe how it functions
