I have 6509-E switch with FWSM , I would like to backup the image from flash of FWSM to tftp sever, but every time I try , it does not communicate with tftp server, even I can ping tftp server address from FWSM.
There are several things that might cause the problem that you describe. One possibility is that something is filtering out the TFTP traffic. Are there any access lists on the 6509 that might impact the TFTP? Or are there access lists (or firewalls) along the data path from the 6509 to the TFTP server that might be impacting traffic?
It is pretty obvious, but are you sure that you are using the correct address of the TFTP server? If you look in the logs of the TFTP server do you see any indication that it is receiving requests from the 6509?
some TFTP servers require that the file exist in the TFTP directory before a remote device can write to it. Might this be an issue on your server?
Seeing the error message is very helpful. It shows that the problem is not a failure to communicate with the TFTP server (so most of my suggestions are off the mark). There is no problem along the path, there are no access lists, and there is no problem with operation of the TFTP server. The problem is that the switch can not access the file and therefore is not attempting to send it to the TFTP server.
I am not sure how you specify the file name to be able to copy the image to TFTP. Perhaps someone else in the forum knows this?
It helps to know that copy tftp of the config file works just fine. It confirms that there is not an issue with TFTP or with the TFTP server.
I am not positive (and if someone in the forum does know for sure I wish they would respond) but I am thinking that the FWSM like some of the other security devices supports TFTP of images to the flash but does not support TFTP of images from the flash.
