624 CHAPTER 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.
Specifying a severity level sends log messages for events or conditions at
that level or higher to the logging destination. Table 54 lists the severity
levels and their descriptions. (For defaults, see Table 53, “System Log
Destinations and Defaults,” on page 624.)
