Working with Configuration Files Appendix B Working with the IOS File System, Configuration Files, and Software Images • For the Trivial File Transfer Protocol (TFTP), the syntax is tftp:[[//location]/directory]/tar-filename.tar The tar-filename.tar is the tar file from which to extract files. For flash:/file-url, specify the location on the local Flash file system into which the tar file is extracted. You can also specify an optional list of files or directories within the tar file for extraction. If none are specified, all files and directories are extracted. This example shows how to extract the contents of a tar file located on the TFTP server at 172.20.10.30. This command extracts just the new-configs directory into the root directory on the local Flash file system. The remaining files in the saved.tar file are ignored. Switch# archive tar /xtract tftp:/172.20.10.30/saved.tar flash:/new-configs Displaying the Contents of a File To display the contents of any readable file, including a file on a remote file system, use the more [/ascii | /binary | /ebcdic] file-url privileged EXEC command: This example shows how to display the contents of a configuration file on a TFTP server: Switch# more tftp://serverA/hampton/savedconfig ! ! Saved configuration on server ! version 11.3 service timestamps log datetime localtime service linenumber service udp-small-servers service pt-vty-logging ! Working with Configuration Files This section describes how to create, load, and maintain configuration files. Configuration files contain commands entered to customize the function of the Cisco IOS software. To better benefit from these instructions, your switch must contain a minimal configuration for interacting with the system software. You can create a basic configuration file by using the setup program or by entering the setup privileged EXEC command. For more information, see Chapter 4, "Assigning the Switch IP Address and Default Gateway." You can copy (download) configuration files from a TFTP, FTP, or RCP server to the running configuration or startup configuration of the switch. You might want to perform this for one of these reasons: • To restore a backed-up configuration file. • To use the configuration file for another switch. For example, you might add another switch to your network and want it to have a configuration similar to the original switch. By copying the file to the new switch, you can change the relevant parts rather than recreating the whole file. • To load the same configuration commands on all the switches in your network so that all the switches have similar configurations.
