Copying Configuration Files to Troubleshoot Configuration
Problems
You can use the file system in Flash memory to copy files and to troubleshoot configuration problems.
This could be useful if you wanted to save configuration files on an external server in case a switch fails.
You can then copy the configuration file to a replacement switch and avoid having to reconfigure the
switch.
Step 1 Enter the privileged EXEC dir flash: commandtodisplaythecontentsofFlashmemoryasinthis
example:
switch: dir flash:
The switch file system is displayed:
Directory of flash:/
3 drwx 10176 Mar 01 2001 00:04:34 html
6 -rwx 2343 Mar 01 2001 03:18:16 config.text
171 -rwx 1667997 Mar 01 2001 00:02:39 c2950-i6q412-mz.121-6.EA2b.bin
7 -rwx 3060 Mar 01 2001 00:14:20 vlan.dat
172 -rwx 100 Mar 01 2001 00:02:54 env_vars
7741440 bytes total (3884509 bytes free)
The file system uses a URL-based file specification. This example uses the TFTP protocol to copy the
file config.text from the host arno to the switch Flash memory:
switch# copy tftp://arno//2950/config.text flash:config.text
You can enter these parameters as part of a filename:
• TFTP
• Flash
• RCP
• XMODEM
Step 2 Enter the copy running-config startup-config privileged EXEC command to save your configuration
changes to Flash memory so that they are not lost if there is a system reload or power outage. This
example shows how to use this command to save your changes:
switch# copy running-config startup-config
Building configuration...
It might take a minute or two to save the configuration to Flash memory. After it has been saved, this
message appears:
[OK]
