Which type of cable is typically used to connect a Cisco router to a console port?

The type of cable typically used to connect a Cisco router to a console port is a rollover cable. This specific cable is designed to connect the router's console port to a terminal or a computer's serial port for configuration and management purposes. Rollover cables are distinctive due to their pinout configuration, where the send and receive pins are reversed, allowing one device to transmit while the other receives.

This design makes rollover cables essential for tasks such as initial router configuration, troubleshooting, and direct access to the router's command line interface. While Ethernet cables and USB cables are used for different types of connections, such as networking or direct device connection, they are not suitable for console access. Serial cables, while sometimes used in similar contexts, do not usually match the specific pinout needed for Cisco console ports.
