Usage Guidelines The log file is stored in ASCII text format. You can use the more privileged EXEC command to display
its contents.
The command rejects the minimum file size if it is greater than the maximum file size minus 1024; the
minimum file size then becomes the maximum file size minus 1024.
Specifying a level causes messages at that level and numerically lower levels to be displayed.
flash:filename The path and name of the file that contains the log messages.
