Usage Guidelines

Usage scenario

It is difficult to locate problems during user access based on debugging information on existing networks because multiple users may get online or offline simultaneously and debugging information about a specified user cannot be displayed. Service diagnosis provided by the wireless access point allows maintenance personnel to customize attributes and create diagnosis objects to diagnose information about services of specified users. To enable service diagnosis, run the trace enable command.

Service diagnosis information can be displayed in two methods:
  • The trace enable brief command configures the device to output brief service diagnosis information.
  • The trace enable command configures the device to output detailed service diagnosis information.

Follow-up Procedure

After service diagnosis is enabled, run the trace object command to create a diagnosis object. After an ID is generated for the diagnosis object, the system starts diagnosis services.


Service diagnosis affects system performance. Therefore, enable service diagnosis only when fault locating is required. After locating faults, immediately run the undo trace enable command to disable service diagnosis.

The trace enable command is not recorded in the configuration file. Therefore, run the trace enable command again after the device restarts to make service diagnosis take effect.


# Enable the service diagnosis function and configure the device to output brief service diagnosis information.
