su (on linux) creates a new shell.

In order to capture the output of that shell, you need to redirect the STDOUT of that shell to a file, then cat that in the original shell.

You appear to be connecting to a network device.
Try to chain the commands into an "sudo" type command, that retains the original shell control.
