Root Cause Analysis
Network infrastructure troubleshooting is a multiple-layer process – from the vague “something’s wrong” to the root cause analysis of a specific problem. The more disciplined the process and the better the understanding of the correlation between network behavior and issue impacting endusers, the faster problems can be resolved or handed off to appropriate teams for remediation
Network Problems
Any network is susceptible to problems that impact performance and output.Fixing problems and restoring the network quickly is crucial to ensure business continuity, but it is far easier said than done. Networks are complicated structures with multiple possible causes for a performance issue.
For example, an issue like slow network speed can result from high bandwidth in the interfaces, an application problem, or protocol latency.
Without proper knowledge about the root cause, taking action will not solve the issue and might prolong the problem as well as skyrocket your network’s mean time to repair (MTTR) metric.

How to troubleshoot network issues?
IT admins need to be prepared to handle network issues and reduce their mean time to repair (MTTR). To achieve a lower MTTR, you should have a clear understanding of network issues.
Network troubleshooting steps.
Step 1
Identify the network issue.
Step 2
Gather information and track the root cause.
Step 3
Troubleshoot the issue.
Step 4
Document the issue, the process and the network troubleshooting solutions.
Network troubleshooting is the process of solving problems that are occurring on your network, using a methodical approach. When users complain, whether they’re internal or external to your organization — or ideally, before they do — you need to figure out what the cause of their problem is. The goal is to troubleshoot and fix whatever issue underlies the problems. Troubleshooting requires taking a methodical approach to resolving the issue as quickly as possible. Unfortunately for you, the user doesn’t care what your service-level objective for fixing the problem is.
