This assignment requires you to: diagnose, correct, and report on commonly occurring

/in /by

This assignment requires you to:

  • diagnose, correct, and report on commonly occurring network misconfigurations.
  • implement best practices for configuring Cisco devices.
  • document your changes.
  • document your diagnostic process.

Download and run the associated Packet Tracer file. In this file you will find a simulation of a set of interconnected networks which have various faults applied to them.

Your task is as follows:

  • Diagnose and correct each fault, verifying that the correct functionality is now present.
    • Note that some of the faults do not necessarily prevent connectivity, but may simply not be best practice.
  • Write a report that shows clearly, for each fault that you discover:
    • What the fault was.
    • What impact the fault had, both locally, and globally within each network, and where appropriate, across all the networks.
    • The process that you used to diagnose the fault (including a chronology of what was attempted that either worked, or didn’t work)
    • How you fixed the fault, being mindful of any potential effects (both positive and negative) that the correction may have more broadly in the network, if any.
  • Analyse devices for compliance with Cisco’s configuration best practices:
    • Determine which devices may not be configured according to best practice
    • Remediate the configuration of those devices, and
    • Document your changes.
