Catalyst 3750 Metro Switch Cisco IOS Commands

Usage Guidelines

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.

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.
