Saving the running configuration
To make your configuration take effect after a reboot, save the running configuration to a configuration
file by using the save command in any view. This command saves all commands that have been
successfully executed, except for the one-time commands. Typical one-time commands include display
commands used for displaying information and reset commands used for clearing information.
For more information about the save command, see Fundamentals Command Reference.
