Usage Guidelines
Use this command to log debug messages to a special log file. This file is more secure and easier to

When you use the debug logfile command to create a log file, the file is automatically created in the log:
directory on the supervisor module unless you specify a different path.
For example, using the debug logfile command to created a log file named captureDebug, you must enter
the dir log://sup-local/? command to find the log file you created. Following example shows you how
to find the log file created.
switch# debug logfile captureDebug

log:
log://sup-local/dmesg
log://sup-local/messages
log://sup-local/captureDebug
switch#
