Configuration Dump
The dump program writes the current switch configuration to the terminal screen. To start the dump
program, at the prompt, enter:
Router(config)# show running-config
The configuration is displayed with parameters that have been changed from the default values. The
screen display can be captured, edited, and placed in a script file, which can be used to configure
other switches. Paste the configuration commands from the script file at the command line prompt of the
switch. The active configuration can also be saved or loaded via FTP/TFTP.
Saving the active switch configuration
When the copy running-config {tftp|ftp} command is used, the active configuration commands
of the switch will be uploaded to the specified script configuration file on the TFTP/FTP server. To start the
switch configuration upload, at the prompt, enter:
Router(config)# copy running-config {tftp|ftp}
NOTE: The output file is formatted with line-breaks but no carriage returns. The file cannot be
viewed with editors that require carriage returns (such as Microsoft Notepad).
NOTE: If the TFTP server is running SunOS™ or the Solaris™ operating system, the specified file must
exist prior to executing the copy running-config tftp command and must be writable (set with
proper permission, and not locked by any application). The contents of the specified file will be
replaced with the current configuration data.
Restoring the active switch configuration
When the copy {tftp|ftp} running-config command is used, the active configuration will be
replaced with the commands found in the specified configuration file. The file can contain a full switch
configuration or a partial configuration.
To start the switch configuration download, at the prompt, enter:
Router(config)# copy {tftp|ftp} running-config
NOTE: The switch supports three configuration files: active, backup, and factory. See the ―Selecting
a configuration block‖ section in the ―Boot Options‖ chapter for information on how to set which
configuration file to use upon boot up.
