The most important part of troubleshooting any problem is to divide the tasks of problem resolution into a systematic process of elimination. Cisco has broken this process into eight steps:
Define the problem.
Gather detailed information.
Consider probable cause for the failure.
Devise a plan to solve the problem.
Implement the plan.
Observe the results of the implementation.
Repeat the process if the plan does not resolve the problem.
Document the changes made to solve the problem.
