    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

WLC: Debug Transfer Trace

The WLC has a wealth of debug commands. I ran into image problems in my lab this weekend.  If you run into TFTP or IMAGE transfer issues a handy debug is the debug transfer trace / tftp enable.

If you have issues contacting the TFTP server from the WLC or image mounting issues this debug will alert you as to the issue.

Here is an example of the debug transfer trace:
