BPDU Guard is a security feature used in network switches. It helps prevent malicious attacks to your network by using Spanning Tree Protocol (STP) configurations. BPDU guard will automatically shut down a port if a BPDU (bridge protocol data unit) is received on that port. This prevents unauthorized access to the network, as well as malicious changes being made to the STP configuration of the switch.
