I want to back up a Cisco Switch, I try to back it up to a tftp server and I get the following error message ..... %Error opening tftp://192.215.36.4/SW1 (Undefined error), I know its the correct IP and I've tried two different computers as TFTP servers and get the same message.

The command I'm using on the Switch is:
SW1#copy running-config tftp .....

I get this erro message:
%Error opening tftp://192.215.36.4/SW1 (Undefined error)

Does anyone know a fix?

Thank you,
DSterling

Double check the syntax (ex copy running-config tftp ?)
Try copy running-config tftp (enter)
192.215.36.4 (enter)
filename (enter)
It will place the config file where every your tftp program is located
Make sure your tftp program is running on 192.215.36.4

also make sure the tftp server is set to take or receive all files as well as give or send all files (security settings on most tftp servers)

The correct syntax to send the config to tftp server is not "copy" but rather "write"

switch#write net
IP address of tftp server:
destination file name:

copy does work on some switches, but not all.  write should work on all switches.

Is SW1 the file name or the directory that the file should be put in?  If it is the directory, make sure that it exists on the tftp sever under the root directory of the tftp sever.  If it is the file name, then make sure the tftp sever has write access to it root directory.

Irmore, how do I make sure that the tftp server is set to take or receive the file?

I was using the directions that my Boson CCNP NetSim uses, but I'll try the write when I get a chance.

thank you,

What tftp server are you using? Each one has different settings.
For example, if using Pumpkin, Options - Server tab, * Give all files,  * take all files
If using TFTPDesktop - File | Properties | Security | [x] No security

For a typical linux tftp server, the file must already exist in the tftp directory.  On the server 'touch <filename>' for the name you wish to save the config under, then go back to the switch and use the write net.  This is a security restriction of the default linux tftp configuration.

I didn't realize that I need to install software on a computer to enable it to allow copying of a Cisco Switch config to it as a TFTP server. I was using a XP Pro laptop computer and trying to copy the Switch config to it. What is a program I could use to enable it as a TFTP server?

I use TFTPd32.  We have also recenlty setup a RANCID (http://www.shrubbery.net/rancid/) sever to automatically pull config files and keep track of changes.  Having RANCID or something like it is great when you have more than a couple switches.
