Chapter 1: Network Principles
Troubleshooting and Maintenance Toolkit
Troubleshooting and maintenance of a network perform together. Both of them are linked with each other. The tools for troubleshooting and maintenance are similar. In this chapter, we will begin with an introduction to Troubleshooting and Network Maintenance and will move to the steps to a managed troubleshooting process by using tools that will help in understanding, identifying the problem, and fixing the issues.
 Problem Identification: By monitoring network devices with tools on a regular basis, you might be informed about issues before the Client is impacted and report about the issue.
 Collection of information: Collection of information when an issue detected or informed by user or by management as well as during scheduled maintenance. While troubleshooting an issue can be made more efficient and easy by using special tools of maintenance and troubleshooting. Here, the network engineer is gathering more information that will help him understand the issue.
 Examination of collected information: After collection of information, the Network Engineer investigates the collected information. By comparing the normal response of the network against the collected response. Network maintenance tools can be used to collect data on a current basis so that it is available and up to date when needed.
 Verification of hypothesis: Troubleshooting tools help a trouble-shooter fix the issue; we can also roll back to previous configuration if the issue is unresolved.
