Working with Configuration Files Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images ! 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. A way to create a basic configuration file is to use the setup program or to enter the setup privileged EXEC command. For more information, see Chapter 3, "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. You can copy (upload) configuration files from the switch to a file server by using TFTP, FTP, or RCP. You might perform this task to back up a current configuration file to a server before changing its contents so that you can later restore the original configuration file from the server. The protocol you use depends on which type of server you are using. The FTP and RCP transport mechanisms provide faster performance and more reliable delivery of data than TFTP. These improvements are possible because FTP and RCP are built on and use the TCP/IP stack, which is connection-oriented. These sections contain this configuration information: • Guidelines for Creating and Using Configuration Files, page B-8 • Configuration File Types and Location, page B-9 • Creating a Configuration File By Using a Text Editor, page B-9 • Copying Configuration Files By Using TFTP, page B-10 • Copying Configuration Files By Using FTP, page B-12 • Copying Configuration Files By Using RCP, page B-15 • Clearing Configuration Information, page B-19 • Replacing and Rolling Back Configurations, page B-19 Guidelines for Creating and Using Configuration Files Creating configuration files can aid in your switch configuration. Configuration files can contain some or all of the commands needed to configure one or more switches. For example, you might want to download the same configuration file to several switches that have the same hardware configuration. Catalyst 2960 Switch Software Configuration Guide B-8 OL-8603-04
