Enables the interface.
A Cisco serial cable, often referred to as a console cable, is a type of communication cable used to connect a computer or terminal to the console port of a Cisco networking device, such as a router or switch. It typically features an RJ-45 connector on one end and a DB-9 or USB connector on the other, facilitating direct access for configuration and management. This cable is essential for initial device setup, troubleshooting, and monitoring, providing a command-line interface for administrators.

show interface status
To verify if a serial interface is operating as a Data Terminal Equipment (DTE) or Data Communication Equipment (DCE), you can use the command show controllers in Cisco IOS. This command displays detailed information about the serial interface, including whether it is configured as a DTE or DCE. The output will typically indicate the role of the device, and a DCE interface will often show the clock rate configuration.
