Enumeration
BPDU guard can operate in all spanning tree modes, but the feature operates with some differences. In SSTP and PVST modes, if a Port Fast-enabled port receives a BPDU,it will be shutdown. In RSTP and MSTP modes, if a port receives a BPDU, it will be blocked for double forward time. In all spanning tree modes, a BPDU guard-enabled port will not send BPDUs.
