Network Modules - Cisco Catalyst WS-C3850-24T-L Product Overview

Network Modules

The port supports Cisco USB Bluetooth devices. The USB Bluetooth device acts as a Bluetooth host and
serves as either a serial port or a management port connection. You can pair it with your Bluetooth smart
phone, laptop, or tablet. If you configure the serial profile on the Bluetooth device, the switch turns the USB
port into a serial port. If you configure the Personal Area Network (PAN) profile on the Bluetooth device, the
switch turns the USB port into a management interface.
