Overview
After a device fault occurs, collect fault information immediately. This helps narrow down the fault scope and allow you to locate the fault accurately. Before fault location, collect the following fault information:
- Fault occurrence time, network topology, operations triggering the fault, fault symptom, measures that you have taken and results, and affected services, see (Mandatory) Collecting the Fault Symptom and Network Topology.
- Name, version, current configurations, interfaces of the faulty device. For the method of obtaining these information, see (Mandatory) Collecting Diagnostic Information and Common display Commands.
- Logs generated when the fault occurs. For the method of obtaining the log information, see (Mandatory) Obtaining Log Information.
