Have you tried changing

copy running-config tftp

copy running-config tftp:

copy flash: tftp: <--- you could specify the directory (if it is required).

Otherwise, check windows firewall, antivirus, etc.

Now the easy way to obtain a backup is using putty and enabling the following settings:

- Right click on putty at the top (gray/white color)

- Clic on logging (left side)

- Select printable output

- Select where are you going to save the config on your laptop

- Finally execute a show run on your device and everything displayed on the screen will be saved on the new file on your computer.

Hope it is useful

🙂

just for kicks, on the 2911 can you do a:

sho run | incl tftp

just to see if there is a tftp source-interface statement? Not very common on the 2911s, in my experience but might be worth checking.

are you able to ping your laptop from the router, before you trying copying the config?

What is this machine acting as a TFTP server? I'd recommend using a different machine.

look at the solarwinds side it should be able to show some activity? like "incomming request" or even a logfile

second option: try to create an empty file first

if so the tftp has write access but no create access, existing files may be overwritten but cannot create a new file.

Sure, basically with putty is copy and paste, as you will generate a file with your entire configuration, you can open the file and copy the config, then just right clic on puty and it will paste the configuration to your router.

Then you can compare the old configuration with the new through:

Oh, compare old and new config?

I just use the command "sh archive config diff <FILE 1> <FILE 2>".
