Explain the three stages of the general troubleshooting process.

Explain the three stages of the general troubleshooting process.

Stage 1: Gather symptoms:

• Symptoms may appear in many different forms, including alerts from the network management system, console messages, and user complaints.
• Gather and document symptoms from the network, end systems, and users.
• In addition, determine which network components have been affected and how the network’s functionality has changed compared to the baseline.

Stage 2: Isolate the problem:

• The problem is not truly isolated until a single problem, or a set of related problems, is identified.
• Examine the characteristics of problems at the logical layers of the network so that the most likely cause can be selected.
• Depending on the problem characteristics identified, gather and document more symptoms.

Stage 3: Correct the problem:

• Work to correct the problem by implementing, testing, and documenting a solution.
