Debugging and logging commands 17 NOTE Use of the flash:// prefix is optional. TABLE 25 Task CEE Flash memory file management commands Command List the files in the Flash memory directory. switch#dir Delete a file from the Flash memory directory. switch#delete flash://example_filename Erase all the files in the Flash memory directory. NOTE: This command erases all the files in the Flash directory except the default startup configuration file which is programmed as a manufacturing default. switch#erase flash % Warning: Erasing flash filesystem will remove all files in flash://. Continue to erase?(y/n):y Rename a file in the Flash. switch#rename filename new_filename Display the contents of a file in the Flash memory switch#show file flash://example_filename directory. Debugging and logging commands Table 26 describes the tasks related to debugging and logging commands on the switch. The Converged Enhanced Ethernet Command Reference contains complete information on all available CLI commands. Perform the following tasks from Privileged EXEC mode. TABLE 26 Task Debugging and logging commands Command Display debugging information for CEE components. switch#show debug Display logging information for CEE components. switch#show logging Display the collection of information needed for technical support. switch#show tech-support NOTE: The supportsave command in Fabric OS includes the debugging data provided by the above commands.
