Usage Guidelines On the Catalyst 3750-switch, the log file is stored in ASCII text format in an internal buffer on a
standalone switch, and in the case of a switch stack, on the stack master. If a standalone switch or the
stack master fails, the log is lost unless you had previously saved it to flash memory by using the logging
file flash:filename global configuration command.
On the Catalyst 3560-switch, the log file is stored in ASCII text format in an internal buffer on the
switch. You can access logged system messages by using the switch command-line interface (CLI) or by
saving them to a properly configured syslog server. If the switch fails, the log is lost unless you had
previously saved it to flash memory by using the logging file flash:filename global configuration
command.
After saving the log to flash memory by using the logging file flash:filename global configuration
command, you can use the more flash:filename 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.
Examples
This example shows how to save informational log messages to a file in flash memory:
Switch(config)# logging file flash:logfile informational
You can verify your setting by entering the show running-config privileged EXEC command.
