Working w ith Configuration Files
•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 loca tio n on the local Flash fil e system into which the tar file is e xtrac ted .
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 e xample sho ws ho w to extra ct the conten ts of a tar f ile loc ated on the TFTP serv er at 172. 20.10.30.
This command extracts just the new-configs dire ctor y into t h e root dir ect ory on the lo cal Fla sh file
system. The remaining files in the saved.tar file are ignor ed.
Switch# archive tar /xtract tftp:/172.20.10.30/saved.tar flash:/new-configs

Displaying the Contents of a File

To di splay the contents of an y readable file, in cluding a f ile on a remote f ile system, use the more [/ascii

Working with Configuration Files

This section describes how to create, load, and maintain configuration files. Configuration files contain
comman ds entere d to custo mize the fu nctio n of the Cisco IO S software. To better bene fit from these
instructions, your switch must contain a minimal configuration for interacting with the system software.
You can cr ea te a b as ic co nfiguration file by u sin g th e setup pr ogram or by ente ring th e setup privileged
EXEC command. For more information, see Chapter 4, “Assign ing the Switch IP Ad dress an d Default
Gateway.”
You ca n copy (download) configuration files from a TF TP, FTP, or R CP se rver to the ru nning
configurati on or st art up configu ratio n o f the swi tch. You might want to perf or m this fo r one o f 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
networ k and want it to ha v e a conf igurat ion similar to the original switch. By copying the f ile to the
new switch, you can c hange the re leva nt part s rather tha n recrea ting the w hole file.
•To load t he sam e configur ati on c omm an ds on al l the sw itche s i n your ne twork so tha t a ll the
switches have similar configurations.
