We had a 3750 with POE stored past warranty. Went to use the switch and something was wrong with software code. A number of interfaces were missing. We reloaded the image via the serial port but had to set the serial port to 115K to speed the process. Now we can't set the serial port back to 9600. Can someone tell me the command to do so? We do use CNA as well. Attempts I have made have been unsuccessful.
