189 Chapter 30 Introducing the Commands
30.9 Using Command History
The switch keeps a list of commands you have entered for the current CLI session. You can
use any commands in the history again by pressing the up (y) or down (z) arrow key to scroll
through the previously used commands and press
[ENTER]. Use the history command to display
the list of commands.
30.10 Saving Your Configuration
After you set the switch settings with the configuration commands, use the write memory
command to save the changes permanently.
Note: The
write memory command is not available in User mode.
You must save your changes after each CLI session. All unsaved configuration
changes are lost once you restart the switch.
30.10.1 Switch Configuration File
When you configure the switch using either the CLI (Command Line Interface) or web
configurator, the settings are saved as a series of commands in a configuration file on the
switch. You can perform the following with a configuration file:
• Back up switch configuration once the switch is set up to work in your network.
• Restore switch configuration.
• Use the same configuration file to set all switches (of the same model) in your network to
the same settings.
