Plan Corrective Action And Resolve The Problem; Verify The Solution To The Problem; Troubleshooting Guidelines - Alcatel 5620 Troubleshooting Manual

1 — Troubleshooting process
The following 5620 SAM features can help you identify the route cause of a
problem:
•
alarms with vendor-specific and X.733 standardized probable causes
•
alarm history associated network conditions

Plan corrective action and resolve the problem

The corrective action required to resolve a problem depends on the problem type.
The problem severity and associated QoS commitments affect the approach to
resolving the problem. You must balance the risk of creating further service
interruptions against restoring service in the shortest possible time. Corrective action
should:
1 Document each step of the corrective action.
2 Test the corrective action.
3 Use the CLI to verify behavior changes in each step.
4 Apply the corrective action to the live network.
5 Test to verify that the corrective action resolved the problem.

Verify the solution to the problem

You must make sure that corrective action associated with the resolution of the
problem did not introduce new symptoms in your network. If new symptoms are
detected, or if the problem has only been mitigated, you need to repeat the
troubleshooting process.

Troubleshooting guidelines

When a problem is identified in the network management domain, track and store
data to use for troubleshooting purposes:
•
Determine the type of problem by reviewing the sequence of events before the
problem occurred:
•
Check the documentation or your procedural information to verify that the steps
you performed followed documented standards and procedures.
•
Check the alarm log for any generated alarms that are related to the problem.
•
Record any system-generated messages, such as error dialog boxes, for future
troubleshooting.
•
If you receive an error message, perform the actions recommended in the error
dialog box, client GUI dialog box, SOAP exception response, or event
notification.

•
Trace the actions that were performed to see where the problem occurred.
•
Identify what changed before the problem occurred.
•
Determine whether the problem happened before under similar conditions.
