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

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

switch# debug logfile captureDebug
switch# dir log://sup-local/?
log: Enter URL "log:[//<module-number>]/<filename>"
log://sup-local/dmesg
log://sup-local/messages
log://sup-local/captureDebug
switch# dir log://sup-local/
