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.
NetIron# write memory
Replacing the running configuration with the startup configuration
If you have not yet executed a write memory command to overwrite the startup configuration with
the running configuration and you want to back out of the changes you have made to the running
configuration and return to the startup configuration, complete the following steps.
1. Enter the following command at the Privileged EXEC level of the CLI.
NetIron# reload
When the system detects differences between the running and startup configurations, it
prompts you as follows.
Running Config data has been changed. Do you want to continue
the reload without saving the running config? (enter 'y' or 'n'):
2. Enter y and press the Enter key
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. The commands must be entered at the Privileged EXEC level of the CLI.
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 NetIron CES and NetIron CER 2000 Series device, the
file is always copied as “startup-config” or “running-config”, depending on which type of file
you saved to the server.
• copy startup-config tftp <tftp-ip-addr> <filename> – Use this command to upload a copy of
startup-config from the NetIron CES and NetIron CER 2000 Series device to a TFTP server.
• copy running-config tftp <tftp-ip-addr> <filename> – Use this command to upload a copy of
the running configuration from the NetIron CES and NetIron CER 2000 Series device to a TFTP
server.
• copy tftp startup-config <tftp-ip-addr> <filename> – Use this command to download a copy of
the startup-config from a TFTP server to a device.
• copy tftp running-config <tftp-ip-addr> <filename> [overwrite] – Use this command to
download the running configuration from the system’s runtime memory to a TFTP server. The
running configuration is then appended to the current configuration of a NetIron CES and
NetIron CER 2000 Series device.
