The first step in enabling port security on a Cisco switch is to enter the interface configuration mode for the specific interface on which you want to enable port security. By using the command to access the interface, you can then configure various settings related to port security for that specific interface.

Once you are in the interface configuration mode, you can then proceed to enable port security and set the necessary parameters, such as maximum number of MAC addresses allowed, violation actions, and more. This step is essential as it specifies which particular port you are configuring, allowing for finer control and management of port security features.

Other configurations mentioned would follow after entering the interface, making this step foundational to enabling port security on a Cisco switch.
