I am trying to upgrade the software of a 3750 switch with ciscoworks. I added the image to the repository, and created a job to push it to a 3750 on the network. The job failed.
Note that Ciscoworks' connection to the device is working properly, through SNMP and telnet.
Looking closely in the switch_telnet.log file, when the switch is trying to copy flash to tftp, there is an %Error writing tftp://... (Timed out)...
Same thing happens later when the switch tried to retrieve the new image from the ciscoworks tftp server: %Error opening tftp://... (timed out)
I double checked that the host based firewall on the ciscoworks server is turned off, and CWCS tftp service is Started. (Ciscoworks is running on Windows 2003).
I have no idea where to look next to get to the source of this problem and fix it. Any ideas and suggestions would be greatly appreciated.
