Guidelines For Creating And Using Configuration Files - Cisco 3200 Series Hardware Reference Manual

Working with Configuration Files
•
You can copy (upload) configuration files from the WMIC 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 Transmission Control
Protocol/Internet Protocol (TCP/IP) stack, which is connection oriented.

Guidelines for Creating and Using Configuration Files

Creating configuration files can aid in your WMIC configuration. Configuration files can contain some
or all of the commands needed to configure one or more access points. For example, you might want to
download the same configuration file to several access points that have the same hardware configuration.
Use these guidelines when creating a configuration file:

To load the same configuration commands on all the access points in your network so that all the
access points have similar configurations.

If no passwords have been set on the WMIC, you must set them on each bridge by entering the
enable secret secret-password global configuration command. Enter a blank line for this command.
The password is saved in the configuration file as clear text.
If passwords already exist, you cannot enter the enable secret secret-password global configuration
command in the file because the password verification will fail. If you enter a password in the
configuration file, the WMIC mistakenly attempts to execute the passwords as commands as it
executes the file.
The copy {ftp: | rcp: | tftp:} system:running-config privileged EXEC command loads the
configuration files on the WMIC as if you were entering the commands at the command line. The
WMIC does not erase the existing running configuration before adding the commands. If a
command in the copied configuration file replaces a command in the existing configuration file, the
existing command is erased. For example, if the copied configuration file contains a different IP
address in a particular command than the existing configuration, the IP address in the copied
configuration is used. However, some commands in the existing configuration might not be replaced
or negated. In this case, the resulting configuration file is a mixture of the existing configuration file
and the copied configuration file, with the copied configuration file having precedence.
To restore a configuration file to an exact copy of a file stored on a server, copy the configuration
file directly to the startup configuration (by using the copy {ftp: | rcp: | tftp:}
nvram:startup-config privileged EXEC command), and reload the WMIC.
