The default console port speed setting is 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. However, both ports always display the switch output.
You can use either port (but not both) for input.
The Cisco Catalyst 3850 Switch (similar to the Cisco Catalyst 3750-X Switch) has two console ports: a USB mini console port in the front and an RJ45 console port in the rear.
