Nebula BPDU Guard is essential when you want to protect your network from unexpected changes caused by new devices joining the network. Specifically, it's used to disable the port once unauthorized devices connect to your network and send BPDU packets.  When BPDU Guard is enabled on a port and it detects Bridge Protocol Data Units (BPDUs, which are used in STP) from an unknown device, it automatically disables that port. This action prevents potential network disruptions or topology changes that could be caused by the unauthorized device.
