Is this true?
If you do not have BPDu Guard configured on a PortFast-enabled port that is receiving configuration BPDUs. the configuration
BPOUs are processed by the switch and eventually the port might be shut down to prevent a loop However, because during this
time the switch is forwarding traffic (because PortFast is enabled), a brdging loop might be formed that could bring dowm the
network before the port is blocked.
