Configuration Commands
Introduction
The Configuration commands are available only from an administrator login. They include commands for
configuring every aspect of the switch. Changes can be saved to non-volatile memory (NVRAM).
The following table describes the basic Configuration commands. The following sections provide more
detailed information and commands.

Viewing and saving changes
As you use the configuration commands to set switch parameters, the changes you make take effect
immediately. You do not need to apply configuration changes when you use the ISCLI. Any changes are
lost the next time the switch boots unless the changes are explicitly saved.
Saving the configuration
You must save configuration changes to flash memory, so the switch reloads the setting when you reset
the switch.
IMPORTANT: If you do not save the changes, they are lost the next time the system is reloaded.
To save the new configuration, enter the following command at any prompt:
Router# copy running-config startup-config
When you save configuration changes, the changes are saved to the active configuration block.
For instructions about selecting the configuration to run at the next system reload, see the ―Selecting a
configuration block‖ section in the ―Boot Options‖ chapter.
