Usage Guidelines Use this command to log debug messages to a special log file. This file is more secure and easier to
process than sending the debug output to the console.
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, when you use the debug logfile command to create a log file named captureDebug, you
must enter the dir log://sup-local/? command to find the log file you created. This example shows you
how to find the log file created:
switch# debug logfile captureDebug
switch#
log:
log://sup-local/dmesg
log://sup-local/messages
log://sup-local/captureDebug
switch#
Examples
The following example redirects the output of the debug commands to the file named sample:
switch# debug logfile sample
The following example assigns the log file size for the file named sample:
switch# debug logfile sample size 410000
