As you test connectivity and isolate problems, maintain a running log of what tests you
perform and their outcomes:
Which devices were pinged or traced?
Were there any failed connections or timeouts?
What diagnostic commands (like `show ip route`, `show interfaces`, or `debug`
commands) were executed?
What hypotheses were formed and how were they tested?
This log is invaluable for keeping track of the investigative process and ensures that no
step is overlooked.
4. Document Changes Made and Their Impact
Every time you modify a setting—be it changing an IP, adjusting a routing protocol, or
modifying an ACL—note the exact change and immediately test the network’s response.
Documenting the before-and-after states helps isolate what fixes the problem and also
highlights any unintended side effects.
5. Summarize the Root Cause and Resolution
Once the issue is resolved, write a concise summary explaining the root cause, how it was
identified, and the steps taken to fix it. This summary acts as a quick reference and
learning tool for future troubleshooting challenges.
