- This section uses an AC as an example. The method of obtaining logs on an AP is similar.
- Logs are saved in the date.time.log or date.time.dblg format in time sequence. After obtaining the log files, you can analyze the log files generated before and after a fault occurs to locate the fault.
- To export user logs and diagnostic logs in V200R008C10 and later versions, run the save logfile command.
For APs that support Bluetooth serial ports, you can also use the CloudCampus APP to export logs. The procedure is as follows:
- After logging in to an AP through the Bluetooth serial port, enable the log recording function to save operation logs.
- After logs are collected, exit and find the newly collected logs in the historical records.
- Send the collected information by email.
