Hi Sintu,
Can you be a little clear on the exact problem description?
You want to take a back up of the running config or the bootloader software?
In any case you need to check whether you have a tftp server configured in your network, if not you can download tftpd32 from http://tftpd32.jounin.net/
This will install the tftp server on your PC.
Log into the switch from your PC type in the following comands
6509#copy run tftp:
Address or name of remote host [10.10.10.2]? 10.10.10.2 // Assuming 10.10.10.2 is your PC (tftp server's) IP
Source filename [running-config]? running-config
Destination filename [running-config]? running-config
You will get a confirmation that the file has been successfully uploaded.
The process is similiar if you want to backup the bootloader software to your tftp server.
The syntax is
6509#copy tftp:
In your case it will be
6509#copy bootflash: tftp:
Address or name of remote host [10.10.10.2]? 10.10.10.2 // Assuming 10.10.10.2 is your PC (tftp server's) IP
Source filename [c6msfc2-boot-mz.121-8b.EX5]? c6msfc2-boot-mz.121-8b.EX5
Destination filename [c6msfc2-boot-mz.121-8b.EX5]? c6msfc2-boot-mz.121-8b.EX5
Let me know if this answers your question.
Cheers,
AB
