7 Loading and saving configuration files Replacing the startup configuration with the running configuration After you make configuration changes to the active system, you can save those changes by writing them to code flash. When you write configuration changes to code flash, you replace the startup configuration with the running configuration. To replace the startup configuration with the running configuration, enter the following command at any Enable or CONFIG command prompt: BigIron RX# write memory Replacing the running configuration with the startup configuration If you want to back out of the changes you have made to the running configuration and return to the startup configuration, enter the following command at the Privileged EXEC level of the CLI: BigIron RX# reload When the system detects differences between the running and startup configurations, it prompts you as follows: Are you sure? (enter 'y' or 'n'): Enter y, and press the Enter key. Logging changes to the startup-config file You can configure a BigIron RX Series to generate a Syslog message when the startup-config file is changed. The trap is enabled by default. The following Syslog message is generated when the startup-config file is changed: startup-config was changed If the startup-config file was modified by a valid user, the following Syslog message is generated: startup-config was changed by To disable or re-enable Syslog messages when the startup-config file is changed, use the following command at the global CONFIG level of the CLI: Syntax: [no] logging enable config-changed Copying a configuration file to or from a TFTP server To copy the startup-config or running-config file to or from a TFTP server, use one of the following methods. NOTE You can name the configuration file when you copy it to a TFTP server. However, when you copy a configuration file from the server to a BigIron RX Series, the file is always copied as "startup-config" or "running-config", depending on which type of file you saved to the server. 190 BigIron RX Installation Guide 53-1001811-01
