I have a cisco 2950 switch .The switch is in use  and i want to backup it's existing IOS.

Whenever I try to backup  using TFTP the switch hangs after sending XX MB of  data and i
have to reboot the switch to make it work again.

I tried it twice and it appears to have hung at the same place.( from the progress bar)

If try to do copy the config it just works fine. Does this mean i have a bad block on my switch flash ? Would formatting the flash will help ? What are my options ?

What TFTP server are you using. There are some problems with certain TFTP servers that cause them to behave badly with larger files. If you aren't already using it, I suggest using Solarwinds TFTP server.

That shouldn't cause a problem for any TFTP server. You might try FTP just to see what happens.

agree with donjohnston.

If you can, I would also try the free tftpd32 for windows.

the alternitive is to connect to the switch through the consol port, and send the file thriough through the consol port.

this way you can completly remove the network from the equation to test what is causing the problem.

I would also sugest using FTP in place of tftp, its much quicker i find and more relible
