By using PortFast feature, the port won’t spend 50 seconds to move from blocking (20sec), listening (15sec), learning (15sec) and finally forwarding but will jump directly to the forwarding state. This feature should be used on ports connected to hosts only because hosts surely don’t send BPDU. An example of configuring PortFast on an interface is shown below:
