To store the configuration or changes you have made to your startup configuration in flash memory, enter
this privileged EXEC command:
Switch# copy running-config startup-config
Destination filename [startup-config]?
Building configuration...
This command saves the configuration settings that you made. If you fail to do this, your configuration
will be lost the next time you reload the system. To display information stored in the NVRAM section
of flash memory, use the show startup-config or more startup-config privileged EXEC command.
For more information about alternative locations from which to copy the configuration file, see
Appendix B, “Working with the Cisco IOS File System, Configuration Files, and Software Images.”
