Working with Configuration Files
Extracting a tar File
To extract a tar file into a directory on the flash file system, use the privileged EXEC command:
archive tar /xtract source-url flash:/file-url [dir/file...]
For source-url, specify the source URL alias for the local file system. These options are supported:
• For the local flash file system, the syntax is
flash:
• For the FTP, the syntax is ftp:[[//username[:password]@location]/directory]/tar-filename.tar
• For the RCP, the syntax is rcp:[[//username@location]/directory]/tar-filename.tar
• For the 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 [dir/file...], specify the location on the local flash file system into which the tar file is
extracted. Use the dir/file... option to specify an optional list of files or directories within the tar file to
be extracted. 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

Working with Configuration Files
This section describes how to create, load, and maintain configuration files. 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 c an co py ( 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.
