Methods of outputting logs to log files on S series switches
The S series switches (except the S1700) support the storage of logs and alarms in the log files. You can run the dir command in the user view to view the log files, which are named syslogfile or logfile. Perform the following steps to obtain logs and alarms from log files: 1. Run the save logfile command to save information in the log buffer to syslogfile or logfile. Remarks: The device automatically saves logs at regular intervals. The syslogfile file is saved automatically every time the device restarts. The logfile file is automatically saved at regular intervals. 2. After running the save logfile command, you can transfer log files to the terminal (PC) through FTP or TFTP.
