How to configure Spanning Tree Port Fast and BPDU Guard on Cisco Switch

In this video, the presenter demonstrates how to configure Spanning Tree Protocol (STP) and Bridge Protocol Data Unit (BPDU) on a network switch. They explain the five states a switch goes through when establishing a link: disabled, listening, learning, forwarding, and blocking. The focus is on avoiding STP for devices like PCs, printers, and servers, which do not require STP since they do not send BPDU. The presenter shows that when a PC is connected, it can automatically enter the forwarding state without going through the other states. They also introduce a feature called BPDU Guard, which prevents BPDU from being sent from connected devices. If a second switch is connected to a port with BPDU Guard enabled, that port will shut down to block BPDU traffic. The presenter demonstrates disabling the port to allow BPDU again, which takes some time to come back up. The video concludes with a practical demonstration of these concepts.
