Thanks again. :)

The IOS can be verified by checking the file size. With that said, the IOS can be obtained from in case the transfer was unsuccessful. I don't see backing up the IOS as a mandatory step.

As for the running-configuration, it will be transferred as a txt file which can be viewed with any text editor.

You can achieve the same results by telneting into the switch and capturing the output of a show run

Since you have a switch, there is an additional vital file you must be aware of - that is 'vlan.dat'. This file stores your Vlan information and depending on how your VTP is configured, you may need or may not need to backup this file.

If you are running VTP server/client mode with other switches, then you don't need to backup this file as a copy is stored in the other switches.

If you are running VTP Transparent, the information is part of the running-configuration thus no extra-step is needed.

Now, if you are running in VTP Server/Client mode and you have no other switches in this environment sharing the VTP database, then you must also backup this file.

Edison, I appreciate your efforts and thank you very much!

Can i use tftp32 as a TFTP server or do i need to go for any high end TFTP server application?

You can use tftp32 for this task but you can also use ftp for this task as well. I stopped using tftp for file transfer a while ago as ftp provides a reliable delivery of packets.

I personally use filezilla for ftp client and server.

Okay, how do i configure FTP client on Catalyst 6500? then how can i do transfer from Catalyst 6500 to filezilla server?

Thanks in advance.

On the copy option, you can either choose ftp or tftp as the destination. The link I provided explains the 'URL' source | destination options.
