624CHAPTER A: TROUBLESHOOTING A WX SWITCH

System events and conditions at different severity levels can be logged to multiple destinations. By default, events at the error level and higher are posted to the console and to the log buffer. Debug output is logged to the trace buffer by default. Table 53 summarizes the destinations and defaults for system log messages.
