If you do a "debug scp all"when attempting to copy across - you will get some useful info. ***Please rate and mark the comment correct if you find it helpful. Just in case you wonder, 0 bytes was copied just because the test file was an empty text file.ģ850 Switch #copy server ip address/test.txt flash:ĭestination filename ? press EnterĠ bytes copied in 13.160 secs (0 bytes/sec) When check mark for scp is enabled, I got no problem copying the test file.

%Error opening ip address/test.txt (Undefined error) It might not be as specific as your "(Protocol error)" but again might be something on the settings. Like in my case, I have to check the ssh/sftp option then a sub-menu that shows to allow scp too.Īs an experiment, when the check mark for scp was removed I got the message below. I don't know what scp software you are using or Mac supports scp natively(not a Mac person) but based on the error message you showed with "(Protocol error)", check your scp server settings. For this test, I used Core FTP Server as my scp software and use Cisco 3850 as my client.
