I'm using SolarWinds TFTP server and will "copy run tftp" to the tftp server and sucessfully copy my running config. I can see the file in the tftp-root folder.
If I try to "copy tftp run" both the router and SolarWinds show an error of "file does not exist"
I can sucessfully upload and download the IOS but not the config file. "Send and recieve" is checked for security and no IP's are blocked.
If I upload the config from routerA and download it back in, it will work. If I upload the RouterA config and try to download it to RouterB, it will not. Both run the same exact IOS and have the same resources. IOS will transfer from routerA to routerB OK as well.
These are both 2620 cisco routers.
