In this video, Tony Fortunato shows how TFTP can be problematic when transferring files between network devices.

In the past, transferring files to or from networking equipment wasn’t as common as it is now. I suspect this is largely due to many factors, including vendors updating their software to meet ever-challenging security risks and clients' interest in logs that may reside on the unit.

I tend to use http myself.  You don't have to worry about active/passive mode, and pretty much every Cisco device supports copying a file from an http device.

The second option I use is usually scp, since it runs over ssh.
