What is port flap?

A port flap refers to a situation when a network port on a network switch rapidly switches between the up and down states. This can happen due to a problem with the physical connection, such as a loose cable or a faulty switch port. A port flap can cause network connectivity issues and disrupt network services as the switch is unable to maintain a stable connection with the affected device. Troubleshooting a port flap can involve checking physical connections, verifying network configurations, or replacing faulty hardware components. To prevent port flaps, it is recommended to use high-quality network cables, regularly inspect and maintain network hardware, and configure network switches to minimize network disruptions.
